The Great Migration is the largest overland movement of mammals left on Earth. Every year, vast herds of wildebeest, zebra and gazelle walk a loop of roughly 800 to 1,000 kilometres through Tanzania's Serengeti and Kenya's Maasai Mara. They follow the rain, the fresh grass and the minerals in the soil. Along the way, they give birth, fight, swim crocodile-filled rivers and feed East Africa's greatest concentration of predators.

We have guided travellers through this ecosystem for more than a decade. As a result, we know that most online guides make the Great Migration sound simpler than it is. The herds do not keep a calendar. They split, double back and spread across thousands of square kilometres. That is why this guide goes deeper. You will learn where the animals usually are each month, why they move, and how to put yourself in the right place at the right time.

You will also find honest 2026 costs, current park fees, the best camps for each season and sample itineraries. In addition, we share the field-tested tips our guides use every day. Whether you dream of a Mara River crossing, a newborn calf on the Ndutu plains or a quiet balloon flight over the herds, this page will help you plan it properly.

Chapter 01

What Is the Great Migration?

The Great Migration is the annual, clockwise journey of the Serengeti's wildebeest and their companions around the Serengeti–Mara ecosystem. It has no true start or finish. Instead, it is a continuous loop that the herds repeat every year, driven by seasonal rain and the grass it produces.

Many travellers imagine one dramatic event, such as a single river crossing. In fact, the migration is a year-long cycle with several distinct chapters. There is the birth of half a million calves in the south. Then comes the rut, when males fight for females. After that, the herds face the rivers of the west and the north. Finally, they turn south again with the short rains.

A loop, not a line

The easiest way to picture the wildebeest migration is as a giant clock face laid over the map. At the bottom sit the short-grass plains of the southern Serengeti and the Ngorongoro Conservation Area. Here, the herds spend roughly December to March. On the left of the clock is the Western Corridor, which stretches towards Lake Victoria. The herds usually pass through it around May and June.

At the top of the clock lies the northern Serengeti and Kenya's Maasai Mara. The herds normally arrive there in July and stay until about October. Then the short rains begin in the south, so the animals swing down the eastern side of the park. By December, most are back on the southern plains, ready to give birth again.

Where does the Great Migration take place?

The entire journey happens inside one connected ecosystem of roughly 25,000 to 40,000 square kilometres, depending on how its edges are defined. The core protected areas are well known:

  • Serengeti National Park, Tanzania — about 14,763 km² and home to the herds for most of the year.
  • Ngorongoro Conservation Area, Tanzania — includes the Ndutu area, a key calving ground.
  • Maasai Mara National Reserve, Kenya — about 1,510 km², famous for its river crossings.
  • The Mara conservancies, Kenya — private, community-owned land bordering the reserve.
  • Grumeti, Ikorongo and Loliondo, Tanzania — game reserves and controlled areas on the park's edges.

Importantly, the animals ignore the international border. For them, the Serengeti and the Mara are one landscape. That is why a well-planned Great Migration safari often looks at both countries before deciding where to go.

Is the Great Migration one of the wonders of the world?

Yes, many people consider it one. In 2006, a panel of experts for a US television series named the Serengeti migration one of the "New Seven Wonders of the World". More importantly, UNESCO listed Serengeti National Park as a World Heritage Site in 1981, and it lists the Ngorongoro Conservation Area too. Both listings highlight the migration as a phenomenon of outstanding universal value. You can read the official UNESCO Serengeti listing for the formal description.

Chapter 02

The Great Migration in Numbers: Wildebeest, Zebra and Gazelle

First of all, numbers give the Great Migration its scale. However, they are also the part most websites get wrong. So here is what the science actually says, including a new study that has sparked debate among researchers.

How many wildebeest are in the Great Migration?

For decades, the accepted figure has been about 1.3 million wildebeest. This number comes from aerial surveys that Tanzanian researchers have flown since the 1970s. Many travel companies round it up to 1.5 or even 2 million animals once zebra and gazelle are added.

In September 2025, however, a team led by Oxford University published a very different result in the journal PNAS Nexus. The researchers trained artificial-intelligence models to count wildebeest on high-resolution satellite images. Their counts found roughly 324,000 to 338,000 animals in images from August 2022. They found about 503,000 to 533,000 animals in images from August 2023.

Does this mean half the herd has vanished? Not necessarily. The satellite images covered about 4,000 km² of the northern Serengeti and south-western Kenya, not the whole ecosystem. The models also cannot yet tell wildebeest from zebra or eland at that resolution. Moreover, animals hidden under trees are missed. The authors themselves call for more surveys that compare methods. You can read the Oxford University summary of the study for the details.

Our honest take

The true number is being debated, and we will update this page as new counts appear. What our guides can confirm is simple. When the herds mass on the southern plains or line up on the Mara River, you will see more animals in one view than you thought possible. Whether it is 800,000 or 1.3 million, the Great Migration remains the most overwhelming wildlife spectacle on the planet.

Meet the cast of the migration

White-bearded wildebeest

The Serengeti's wildebeest are the western white-bearded wildebeest (Connochaetes mearnsi). They are the engine of the migration. Wildebeest are fussy grazers that need short, nutritious grass, so they must keep moving.

Plains zebra

Around 200,000 plains zebra travel with the herds. They eat the longer, tougher grass tops. As a result, they often lead the way and "mow" the grass for the wildebeest that follow.

Thomson's & Grant's gazelle

Several hundred thousand gazelle follow the larger grazers. They nibble the fresh, low shoots that appear after the bigger animals have passed.

Eland

The world's largest antelope also joins parts of the journey in smaller numbers. Eland are shy, so spotting a herd is always a bonus.

The predators that follow the herds

Naturally, where there is food, there are hunters. The Serengeti holds one of Africa's largest lion populations, often estimated at around 3,000 animals. Spotted hyenas are even more numerous and often commute long distances to feed on the herds. Cheetahs gather on the open southern plains during calving season, while leopards hunt from the riverine trees. In the rivers, huge Nile crocodiles wait for the crossings. Overhead, several species of vulture clean up what the others leave behind.

Life and death in numbers

The Great Migration is also a story of loss. Researchers estimate that hundreds of thousands of wildebeest die each year from predation, exhaustion, disease, drowning and old age. A study published in PNAS in 2017 found that an average of about 6,250 wildebeest drown in the Mara River every year. Their carcasses add roughly 1,100 tonnes of biomass to the river, which feeds fish, birds and crocodiles. In other words, even death on the migration fuels the ecosystem.

Chapter 03

Why Do the Wildebeest Migrate? The Science Explained

Wildebeest do not migrate for adventure. They migrate because staying still would mean starving. Three forces drive the Great Migration: rainfall, grass quality and minerals. Understanding them helps you predict where the herds will be.

1. Rain drives the grass, and the grass drives the herds

The Serengeti has two rainy periods. First, the "short rains" usually fall in November and December. Then the "long rains" normally fall from March to May. In between, the land dries out. Meanwhile, rainfall is lowest in the south-east and highest in the north-west, near Lake Victoria.

Consequently, the herds follow a clear pattern. When the southern plains turn green after the short rains, the wildebeest head south. When those plains dry out around May, they move west and north towards areas with more reliable rain. Finally, the Maasai Mara and the northern Serengeti offer green grass through the long dry season, so the herds spend July to October there.

2. Short grass is the richest grass

Not all grass is equal. In fact, young, short grass holds more protein and more minerals than tall, dry stems. Wildebeest have relatively small mouths and strong preferences, so they seek out the most nutritious patches. Scientists have shown that the herds track the "green wave" of fresh growth across the landscape, rather than simply following the rain clouds.

3. The volcanic soil secret

Here is the part many guides leave out. The southern Serengeti plains sit on ash from the volcanoes of the Ngorongoro highlands, including Ol Doinyo Lengai. This volcanic soil is unusually rich in phosphorus and calcium. Both minerals are vital for pregnant and nursing mothers, because calves need them to build strong bones and milk supplies depend on them.

That is why the wildebeest return to the southern plains every year to give birth, even though water there is scarce. The grass on these plains is short, sweet and packed with minerals. For a nursing mother, no other place in the ecosystem compares during the wet season.

4. Grazing succession: teamwork without trying

The migrating species do not compete as much as you might think. Zebra eat the coarse upper parts of the grass. Wildebeest then crop the leafy middle layer. Finally, gazelle feed on the tender new shoots close to the ground. Ecologists call this "grazing succession". It allows far more animals to share the same grassland than any single species could support.

5. Safety in numbers

Moving in huge herds also protects individuals. A lion can only catch one animal at a time. So the more animals around you, the lower your personal risk. In addition, many eyes and ears spot danger quickly. Researchers have also found that wildebeest herds make collective decisions. Small groups follow others that seem to know where good grazing lies, which is why you see those famous single-file columns stretching to the horizon.

A comeback story: rinderpest and the growth of the herds

The Great Migration we see today is partly the result of a conservation success. In the early 1960s, the Serengeti held only about 250,000 wildebeest. A cattle disease called rinderpest had killed huge numbers of wild animals across Africa. Once vaccination of cattle stopped the disease spreading, the wildebeest population grew fast. By the late 1970s, aerial counts recorded well over one million animals. The population has stayed roughly at that level ever since, according to the traditional survey method.

Guide's tip: Watch the sky, not the calendar. If you see dark rain clouds building over the southern plains in December, the herds will usually arrive within days. Our guides track rainfall reports and fellow guides' sightings every morning, which is why we plan camps around the likely herd position, not a fixed date.

The Great Migration Month by Month

Now let us walk through the year in detail. For each month, you will find the usual herd position, the highlights, the weather and our preferred base. Use it together with the map above. And remember: the Great Migration follows the rain, so treat every month as a guide rather than a guarantee.

Wildebeest move in long single-file columns between grazing areas, sometimes stretching for kilometres.

Great Migration in January

Southern Serengeti · Ndutu · Kakesio · Lake Masek

In January, the herds have usually settled on the short-grass plains of the southern Serengeti and the Ndutu area. The short rains have turned the land green, and the grazing is excellent. As a result, the animals spread out widely and stay put for weeks at a time.

Calving often begins late in the month, especially if the rains came on time. Predators are already gathering. Lions, cheetahs and hyenas patrol the edges of the herds, so hunting sightings are common. January is also warm and fairly dry, with short afternoon showers. Visitor numbers are moderate, which makes it a rewarding and slightly cheaper alternative to February.

Best base: a seasonal mobile camp or a lodge near Lake Ndutu or Lake Masek.

Great Migration in February

Southern Serengeti · Ndutu · Naabi Hill · Gol Kopjes

February is the heart of calving season and, in our view, one of the two best months of the year. Most calves are born within a few weeks, often cited as around 8,000 births a day at the peak. You can watch a calf stand within minutes of birth and run with its mother soon after.

Naturally, the predators take advantage. Cheetah families hunt on the open plains, lion prides stalk the herds and hyenas work at night. In other words, February offers constant action and dramatic photography. The weather is usually warm with occasional storms, which create stunning skies. Because it is so popular, the best Ndutu camps fill early, so we suggest booking nine to twelve months ahead.

Best base: Ndutu or the southern plains, ideally at a camp inside the calving zone.

Great Migration in March

Southern Serengeti · Ndutu · Moru Kopjes

In March, the calves are stronger and the herds remain in the south. However, the long rains usually begin towards the end of the month. Grass starts to thin on the plains, and the herds begin to gather in larger groups before moving.

Predator action stays high, and the green landscapes are beautiful. Meanwhile, lower visitor numbers and "green season" rates make March excellent value. The main trade-off is rain. Afternoon storms become more frequent, and some tracks turn muddy. Still, a good guide and a sturdy 4x4 manage well. For photographers, the dramatic light before a storm is a real bonus.

Best base: Ndutu or the southern Serengeti, with a night or two in central Serengeti.

Great Migration in April

Southern & central Serengeti · Moru · Seronera

April is the wettest month in the Serengeti. The herds usually leave the southern plains and move north-west through the Moru Kopjes and central Serengeti. They often travel in huge, slow columns that stretch for kilometres.

Some camps close during April, and a few roads become difficult. On the other hand, the parks are nearly empty and prices drop sharply. If you like solitude and do not mind rain, April can be surprisingly rewarding. The resident wildlife of central Serengeti also remains excellent all year, especially lions and leopards around Seronera. Just go with realistic expectations and a flexible plan.

Best base: a permanent lodge in central Serengeti near Seronera.

Great Migration in May

Central Serengeti · Western Corridor

In May, the rains ease and the herds push west towards the Western Corridor. This is also the main month of the rut, the wildebeest mating season. Males become loud and aggressive. They grunt, chase rivals and try to hold small groups of females.

The sound alone is unforgettable. At night, you may hear a constant chorus of snorts and grunts around camp. Meanwhile, the landscape is lush and green, and visitor numbers stay low. Late May can bring the first gatherings along the Grumeti River. Because this is a shoulder month, many camps still offer lower rates, which makes May a clever choice for value-focused travellers.

Best base: central Serengeti early in the month, then the Western Corridor.

Great Migration in June

Western Corridor · Grumeti River · Kirawira · Northern move begins

June is the prime month for the Grumeti River crossings. The river is smaller than the Mara and often forms a chain of pools. Even so, it hosts some of the largest crocodiles in East Africa. When the herds cross, the crocodiles strike.

By mid to late June, part of the herd usually starts moving north through the Ikorongo and Lobo areas. Therefore, June offers flexibility: you can base yourself in the west or the north, depending on the year. The dry season begins, skies clear and temperatures are pleasant. As a bonus, peak-season pricing has not yet started in many camps.

Best base: the Western Corridor or Grumeti Reserve, with a second camp further north.

Great Migration in July

Northern Serengeti · Kogatende · Lamai · Maasai Mara

In July, the herds usually reach the northern Serengeti. The first Mara River crossings often happen during this month, although timing varies from year to year. Some groups also push across into Kenya's Maasai Mara, where the Loita wildebeest from the east arrive at a similar time.

July marks the start of peak season. Game viewing is superb, the weather is dry and cool in the mornings, and the grass starts to turn gold. However, demand soars. Crossing-point camps sell out months in advance, and park fees in Kenya reach their high-season level. Early July can be a sweet spot, because the herds are close and crowds are still building.

Best base: Kogatende or Lamai in Tanzania, or a Mara conservancy in Kenya.

Great Migration in August

Maasai Mara · Northern Serengeti · Mara River

August is the most famous month of the Great Migration. The herds spread across the Maasai Mara and the northern Serengeti, and they cross the Mara River again and again. The animals do not cross once. Instead, they move back and forth as grazing and rain change, which is why crossings can happen many times a week.

This is also the busiest month. On the Kenyan side, dozens of vehicles may gather at popular crossing points. On the Tanzanian side, the northern Serengeti is quieter, although it is busier than it was ten years ago. Our advice is to pick a camp close to the river and allow at least four nights, so you have time to wait for the action.

Best base: a camp near the Mara River on either side of the border.

Great Migration in September

Northern Serengeti · Maasai Mara · Mara conservancies

September often matches August for crossings but with slightly fewer visitors. The herds remain in the north, and the grass has now been grazed short in many areas. As a result, predators have plenty of targets and hunting sightings stay excellent.

Many of our returning guests choose September for exactly this reason. The weather is dry, warm by day and cool at night. Visibility is excellent because the grass is short. Moreover, some camps begin to ease prices at the very end of the month. If you want the classic river crossing with a little more breathing room, September is hard to beat.

Best base: Kogatende, Lamai or a Mara conservancy near the river.

Great Migration in October

Northern Serengeti · Maasai Mara · Lobo

In October, the herds usually start drifting south again. Crossings still happen, often in the opposite direction as animals return from Kenya to Tanzania. The first short rains may appear late in the month, which triggers the movement.

October is a quieter and often more affordable month. Game viewing in the Mara and northern Serengeti stays strong, and predators are in top condition after months of plenty. However, the herds are more scattered, so sightings of huge masses of animals become less predictable. For flexible travellers, it is a fine month to combine migration viewing with other parks.

Best base: northern Serengeti early in the month, then Lobo or central Serengeti.

Great Migration in November

Eastern Serengeti · Lobo · Central Serengeti

November brings the short rains, and the herds respond fast. They stream south along the eastern side of the park, through the Lobo area and towards central Serengeti. Movement is the theme of the month. You may see long columns walking steadily through the woodlands.

November is low season, so prices drop and the parks are calm. The landscape turns green again, and migratory birds arrive from Europe and Asia. Because the herds move quickly, a flexible itinerary with a good guide is especially helpful. We usually suggest two camps, one in central Serengeti and one further south, to cover the likely positions.

Best base: Lobo or central Serengeti, with an option to move south.

Great Migration in December

Central & southern Serengeti · Ndutu

By December, most of the herds are back on the southern plains or close to them. The grass is fresh, the calves are not yet born and the animals begin to settle. Early calving sometimes starts at the very end of the month.

December combines good game viewing with festive-season travel. Consequently, the Christmas and New Year period is busy and priced at peak rates. Early December, however, can be excellent value. It is also a lovely time for a family safari, because it fits school holidays and pairs perfectly with a beach break in Zanzibar.

Best base: Ndutu or the southern Serengeti, with a night in central Serengeti if the rains are late.

Chapter 06

Calving Season: The Great Migration's Most Underrated Chapter

River crossings get the headlines. However, many of our most experienced guides say the calving season is the true highlight of the Great Migration. It is intimate, emotional and full of predator action, and it happens with far fewer vehicles around.

When and where is calving season?

Calving usually runs from late January to March, with a peak in February. It takes place on the short-grass plains of the southern Serengeti and the neighbouring Ndutu area inside the Ngorongoro Conservation Area. Popular areas include Lake Ndutu, Lake Masek, Kakesio, Naabi Hill and the Gol Kopjes.

Why are so many calves born at once?

Wildebeest carry their young for about eight to eight and a half months after the rut in May and June. Then most females give birth within a short window of two to three weeks. Scientists call this "birth synchrony". It is a clever survival strategy. Predators can only eat so much, so when hundreds of thousands of calves arrive together, a far larger share survive. In addition, the rich volcanic grass helps mothers produce the milk their calves need.

What will you see during calving season?

  • Births in the open: it is common to watch a calf being born and taking its first steps.
  • Cheetah hunts: the flat, open plains are perfect cheetah country, so families often hunt in plain view.
  • Lion and hyena action: resident prides and hyena clans follow the herds closely.
  • Huge herds: the animals spread across the plains as far as you can see, especially in February.
  • Green landscapes: dramatic skies, wildflowers and perfect photographic light.

Calving season tips from our guides

First, choose a camp inside the calving zone. Driving in from central Serengeti each day wastes precious hours. Second, go off-road where the rules allow it. Driving off established tracks is permitted in parts of the Ndutu area within the Ngorongoro Conservation Area, but not across most of Serengeti National Park, so your camp's location matters. Third, allow at least four nights. Births and hunts happen at random, and more time means more chances.

Why we love February for first-timers

You get the Great Migration, the Big Cats and baby animals in one trip. Crowds are lighter than in August, and the landscape looks lush. Pair it with the Ngorongoro Crater and a few days in Zanzibar, and you have the perfect first safari.

Chapter 07

The Grumeti River Crossings in the Western Corridor

Before the herds reach the Mara River, many of them face a different obstacle: the Grumeti River. It flows west through the Serengeti's Western Corridor towards Lake Victoria. For travellers, it offers a quieter and less predictable, yet thrilling, crossing experience.

When do the Grumeti crossings happen?

The Grumeti crossings usually take place from late May to early July, with June as the most reliable month. However, the timing depends heavily on the long rains. A late or heavy rainy season can push the crossings into July, while a dry year can bring them forward.

What makes the Grumeti different from the Mara?

Compared with the Mara, the Grumeti is smaller and slower. In the dry season, it often shrinks into a string of deep pools and channels. That sounds less dramatic, yet the river holds some of the largest Nile crocodiles in Africa. These giants may eat only a few big meals a year, so the crossings are a vital feast for them.

Crossings on the Grumeti can also be less concentrated. Instead of one mass leap from a steep bank, you may see smaller groups crossing at several points. On the plus side, far fewer vehicles visit the Western Corridor, so you often have the scene to yourself.

Where to stay for the Grumeti crossings

The best bases lie in the Western Corridor, near Kirawira and the Grumeti River, or in the private Grumeti Game Reserve. The private reserve offers exclusive access, walking safaris and night drives, which are not allowed inside the national park itself. Alternatively, you can combine two nights in the west with three nights in the north. This covers both the Grumeti and the early Mara River crossings in one trip.

Chapter 08

Mara River Crossings: The Great Migration's Most Dramatic Moment

No image defines the Great Migration more than a wildebeest leaping from a steep bank into the Mara River. Crocodiles surge forward, dust fills the air and thousands of animals push across in panic. It is raw, loud and, above all, unforgettable. Here is everything you need to know to see it well.

A Mara River crossing can last a few minutes or more than an hour. Patience is the key to seeing one.

When are the Mara River crossings?

The Mara River crossings usually take place between July and October. August and September are the most reliable months. That said, the first crossings can happen in late June in an early year, and a few can still occur in November. Since the herds cross in both directions, there is no single "crossing day". Instead, there are many crossings over several months.

Where does the Mara River flow?

The Mara River rises in Kenya's Mau Forest. It flows south through the Maasai Mara, crosses into Tanzania and runs through the northern Serengeti before turning west to Lake Victoria. The herds meet it in two main areas: the Maasai Mara National Reserve and the Mara Triangle in Kenya, and the Kogatende and Lamai areas in Tanzania.

How does a river crossing unfold?

Crossings follow a surprisingly regular pattern. First, the herds gather on the bank, sometimes for hours or even days. They mill around, approach the water, then turn back. After all, nobody wants to go first. Then, suddenly, one animal jumps or walks in. Within seconds, the rest follow in a rush.

Once the crossing starts, it can last from a few minutes to more than an hour. Zebra often cross in tighter family groups and may go first. Crocodiles pick off the weak or unlucky. Meanwhile, lions sometimes wait on the far bank. Many animals drown in the crush, especially at steep exits. Then, just as suddenly, the herd stops, and the river falls quiet.

Why do wildebeest cross the river at all?

The herds cross because the grazing on the other side is better, or because rain has fallen somewhere nearby. Wildebeest also react to the movement of other groups, so a crossing in one place often triggers another. Some crossings appear almost random, with the same herd crossing back the following day. Scientists still debate how much is decision and how much is simply the herd following itself.

How to maximise your chances of seeing a crossing

  • Stay close to the river. A camp within 20–30 minutes of the crossing points is ideal, because you spend less time driving.
  • Stay long enough. We recommend at least four nights in the north during crossing season, so you have time to wait.
  • Take a packed lunch. Full-day game drives let you wait patiently while herds gather.
  • Trust your guide. Experienced guides read the herd's behaviour and, in addition, share sightings by radio.
  • Be ready to leave. Sometimes a herd gathers for hours and never crosses. Moving on may find you a better spot.
  • Consider both countries. Crossing points in Tanzania are often quieter than those in Kenya, especially in September.

Crossing etiquette and park rules

At a crossing, the animals must come first. In recent years, both the Maasai Mara authorities and the Mara Conservancy have introduced stricter rules. Vehicles must wait well back from the river until the herds commit to crossing. They must also leave the landing zones clear, so animals are not blocked or panicked.

Our guides follow these rules strictly, and we encourage every guest to support them. A blocked crossing can turn back an entire herd and lead to far more drownings. In other words, a respectful distance is not just good manners. It protects the Great Migration itself.

Guide's tip: Listen before you look. A crossing often starts with a sudden change in sound: the grunting of the herd rises, then drops, then dust appears near the bank. When our guides hear that pattern on a still morning, they start the engine.

Want to be on the riverbank when it happens?

Our specialists track the herds daily and hold space at the best crossing camps. Share your dates, and we will tell you honestly which side of the river gives you the best odds.

The best month overall

If we had to pick one month for a first Great Migration safari, it would be February for Tanzania or August for Kenya. February gives you the calving spectacle and big cats with fewer vehicles. August gives you the highest chance of a Mara River crossing. For the best of both, many of our guests choose late July or September in the northern Serengeti.

Dry season vs green season

The dry season runs from about June to October. Grass is short, animals gather near water and roads are easy. However, it is also the busiest and most expensive period. The green season runs from November to May. It brings lush scenery, newborn animals, migratory birds and lower prices. In return, you should expect some rain, usually as short afternoon storms rather than all-day downpours. Only April and early May are truly wet.

Great Migration 2026 and 2027: what to expect

In a typical late September, the herds are spread across the northern Serengeti and the Maasai Mara, with crossings in both directions. The usual southward drift then begins in October as the short rains arrive. For live updates on the 2026 herds, message our team; our guides share fresh sightings every week.

For 2027, we recommend planning your Great Migration safari now. Peak river-crossing camps for July to September 2027 typically sell out eight to ten months ahead. Popular calving camps for February 2027 fill even earlier. If you travel in these months, securing your camp is far more important than fine-tuning your exact dates.

Guide's tip: Build flexibility into the plan, not just the dates. A split stay — for example, three nights at Kogatende and three in a Mara conservancy — covers both sides of the river. That protects you if the herds are late, early or simply stubborn.

Serengeti vs Masai Mara: Where Should You See the Great Migration?

This is the question we hear most often. The short answer is that Tanzania hosts the Great Migration for about nine months of the year, while Kenya hosts it for about three to four. Yet the Maasai Mara offers some of the most accessible crossings and the best conservancies in Africa. So the right choice depends on when you travel and what you value.

Choose the Serengeti if…

  • You travel between November and June, when the herds are only in Tanzania.
  • You want the calving season and, above all, big-cat action on open plains.
  • You prefer vast, wild spaces and also quieter crossing points.
  • You plan to add the Ngorongoro Crater and a Zanzibar beach escape.

Choose the Maasai Mara if…

  • You travel between July and October and have limited time.
  • You want short flights, because Nairobi is less than an hour away.
  • You like private conservancies, since they offer night drives and walks.
  • You want to combine the migration with Uganda's gorillas or Kenya's other parks.

What are the Mara conservancies?

The conservancies are private wildlife areas on land owned by Maasai families. Tourism camps lease the land and pay the owners directly. In return, the landowners keep the land open for wildlife. Popular examples include Mara North, Olare Motorogi, Naboisho, Ol Kinyei and Lemek.

Crucially, conservancies limit the number of beds and vehicles. That means fewer cars at sightings, and many also allow off-road driving, walking safaris and night drives. The herds do not always cross the Mara River inside the conservancies. However, guests can drive into the main reserve for crossings and return to a peaceful camp afterwards. For many travellers, this is the best of both worlds.

What is the Mara Triangle?

The Mara Triangle is the western part of the Maasai Mara National Reserve, across the river from the main reserve. It is managed by a non-profit organisation, the Mara Conservancy, on behalf of the county government. The Triangle is known for strong ranger patrols, well-maintained roads and firm crossing rules. It charges its own entry fees, so check your itinerary carefully.

The Loita migration: Kenya's lesser-known herds

Few travellers know that Kenya has a second, smaller wildebeest migration. The Loita wildebeest live on the Loita Plains, north-east of the Maasai Mara. During the rains, they graze those plains. Then, as the dry season begins, they move west into the Mara, usually arriving around the same time as the Serengeti herds.

As a result, the Mara can hold two populations at once from July onwards. However, the Loita herds have declined sharply over the past few decades. Fencing, wheat farming and settlement have blocked many of their old routes. That is why the Mara conservancies matter so much. Because they pay landowners to keep land open, they also keep space for wildlife to move.

Can you do both countries on one trip?

Yes, and it is often the best option in July, August and September. However, there is no open tourist border crossing inside the ecosystem. You usually fly between the two, typically via Nairobi and Kilimanjaro or Arusha. This takes about half a day and adds a little cost. In return, you double your chances of crossings and see two very different safari styles. Browse our full collection of safari itineraries for options that combine both countries.

Chapter 11

Where to Stay on a Great Migration Safari

Above all, location is everything on a Great Migration safari. The best camp in the world is useless if the herds are 150 kilometres away. Therefore, we always choose the area first and the camp second. Below are our recommended areas by season, with examples across our three travel styles: Comfort & Value, Premium and Luxury.

Permanent lodges vs mobile migration camps

There are two main types of accommodation. Permanent lodges and camps stay in one place all year. They often have pools, spas and larger rooms. Mobile or seasonal camps move two or three times a year to follow the herds. They are comfortable tented camps with proper beds, en-suite bathrooms and hot bucket showers. Because they move with the Great Migration, they put you right among the animals.

For the best wildlife, we often mix both. For example, you might spend three nights in a mobile camp near the herds and two nights in a permanent lodge in central Serengeti or near the Ngorongoro Crater.

Availability and camp positions change every season, so treat these as examples rather than a fixed list. Browse our full lodge and camp collection, or ask us to shortlist camps for your exact dates and budget.

Guide's tip: Ask how far a camp is from the action, not just how lovely it is. During crossing season, a camp 20 minutes from the river can give you two extra hours of viewing every day compared with one 90 minutes away.

Chapter 12

Ways to Experience the Great Migration

A Great Migration safari is not only about game drives. The best trips mix different perspectives, from the sky, on foot and through the eyes of the Maasai people. Here are the experiences we recommend.

Game drives with a specialist guide

Of course, most of your time goes on game drives in an open-sided or pop-up-roof 4x4. A great guide makes all the difference. He or she knows the herds, reads animal behaviour and understands where predators are likely to hunt. For this reason, we only work with guides who have years of migration experience. Full-day drives with a packed lunch are ideal during calving and crossing seasons, because the action rarely follows a timetable.

Hot air balloon safari over the herds

A sunrise balloon flight is one of the great safari experiences. You float silently above the plains as the herds spread out beneath you. Flights usually last about an hour and end with a champagne bush breakfast. Balloons operate in several parts of the Serengeti, including the central, southern, western and northern areas, depending on the season. They also operate in the Maasai Mara. Expect to pay roughly US$550–750 per person, and book early for peak months.

Walking safaris

Walking is not allowed in most of Serengeti National Park without special permits. However, walks are offered in the Mara conservancies, in private reserves such as Grumeti, and in some Serengeti concessions. Walking with an armed guide and a Maasai tracker changes how you see the bush. You notice tracks, dung, birds and plants that you miss from a vehicle.

Night drives

Night drives reveal a hidden world: hyenas hunting, leopards on the move, aardvarks, bat-eared foxes and servals. They are not allowed inside the national parks or the main Maasai Mara reserve. Nevertheless, most Mara conservancies and private reserves offer them. If nocturnal wildlife interests you, choose your camps accordingly.

Fly-in vs drive-in safaris

On a drive-in safari, your guide and vehicle stay with you for the whole trip. This builds a strong relationship, and you see the landscape change between parks. It usually costs less. On a fly-in safari, you take light aircraft between airstrips such as Seronera, Kogatende, Ndutu and the Mara strips. You save long drives and reach remote areas quickly. Many of our guests choose a mix: drive the Northern Circuit through Tarangire and Ngorongoro, then fly to the northern Serengeti.

Cultural visits with the Maasai

The Maasai have lived alongside the herds for centuries. In fact, the word "Serengeti" comes from the Maa word siringet, often translated as "endless plains" or "the place where the land runs on forever". A respectful visit to a Maasai community helps you understand how people and wildlife share this land. We favour visits that are community-run and pay families fairly, rather than staged tourist villages.

A day on a Great Migration safari

What does a typical day look like? Here is a real-world example from one of our crossing-season trips in the northern Serengeti.

05:45 — Wake-up call. Coffee and biscuits arrive at your tent as the sky turns orange. It is cool, so you pull on a fleece. Then, a few minutes later, you hear wildebeest grunting somewhere beyond the camp.

06:15 — First light on the plains. You set off with your guide. Within minutes, you pass a lioness watching a herd, and a pair of jackals trotting home. The light is soft and golden, so photographers get their best shots now.

08:30 — Bush breakfast. Your guide stops under a lone acacia tree. You eat fresh fruit, eggs and bread while thousands of wildebeest move in the distance. Meanwhile, the guide checks the radio for news of herds gathering at the river.

10:00 – 14:00 — The waiting game. Now the herd builds up on the bank. You wait, engine off, at a respectful distance. Sometimes nothing happens. Other times, suddenly, the first animal jumps. For the next 40 minutes, you forget to breathe.

14:30 — Picnic lunch and a slow drive back. After the crossing, you find a shady spot for lunch. Then you drive back slowly, stopping for giraffe, elephants and a leopard draped over a sausage tree.

18:00 — Sundowners. Back at camp, you watch the sun set with a cold drink. Later, dinner is served under the stars, and the day's stories begin. Finally, you fall asleep to the sound of hyenas whooping in the dark.

Private vehicle and exclusive guiding

On every Paramount safari, you have a private vehicle and guide. That means you decide how long to stay at a sighting. It is the single biggest upgrade for photographers and for anyone who wants to wait for a crossing without compromise.

Chapter 13

Great Migration Photography Guide

The Great Migration is one of the most photographed events on Earth. Yet many travellers come home with blurry herds and grey skies. Here is how to do better, based on our guides' years of working with professional and amateur photographers.

The right camera gear

  • A telephoto zoom: a 100–400 mm or 150–600 mm lens covers most situations.
  • A wide-angle lens or phone: essential, because only a wide view shows the scale of the herds.
  • A second body or bridge camera: avoids changing lenses in the dust.
  • A beanbag: far more useful than a tripod, because it rests on the vehicle window.
  • Plenty of memory cards and batteries: crossings can fill a card in minutes, so bring spares.
  • Dust protection: a rain cover or pillowcase and a blower brush.

Camera settings for river crossings

Crossings are fast and chaotic. Use a shutter speed of at least 1/1600 second to freeze splashing water and leaping animals. Continuous autofocus and burst mode are essential. Try a slightly narrower aperture, such as f/8, for more depth when many animals fill the frame. Meanwhile, set auto-ISO with a sensible upper limit, so your camera can adjust as clouds pass.

Creative ideas beyond the obvious

First, capture the scale. Shoot wide to show a column of wildebeest stretching to the horizon. Second, try slow shutter speeds, around 1/15 to 1/30 second, while panning with a running herd. This creates beautiful motion blur. Third, look for dust. Backlit dust at sunrise or sunset turns a herd into a golden, dreamlike scene. Finally, remember the details: a calf's first steps, a crocodile's eye or vultures on a branch.

Ethics behind the lens

No photo is worth disturbing the animals. Never ask your guide to move closer to a crossing point once the herd is gathering. Likewise, avoid flash and keep noise low. The best wildlife photographers are patient, and patience is exactly what the Great Migration rewards.

How Much Does a Great Migration Safari Cost in 2026–2027?

Costs vary widely. Therefore, it helps to know what drives them. The biggest factors are the season, the camps, how you travel between parks and how many nights you stay. Below you will find realistic price ranges, current park fees and our tips for getting the best value.

Typical price per person per night

Travel styleGreen season (Nov – May*)Peak season (Jun – Oct, Christmas)What you get

LuxuryUS$900 – 1,700US$1,300 – 2,500+Top camps, exclusive concessions, flying between regions

*February and the Christmas–New Year period are often priced as peak in the southern Serengeti. Prices are per person sharing, and are indicative. Your exact quote depends on dates, camps and group size.

2026 park and conservation fees

Park fees are a large part of the cost, and they have risen in recent years. The table below shows the main fees for non-resident adults, as published at the time of writing. Fees can change at short notice, so we always confirm them in your final quote.

FeeNon-resident adultNotes

Sources: Tanzania National Parks (TANAPA), Ngorongoro Conservation Area Authority, Mara Conservancy and Narok County. Always check the latest fees before you travel.

Other costs to budget for

  • International flights to Nairobi (NBO), Kilimanjaro (JRO) or Arusha.
  • Light-aircraft flights between parks, often US$250–500 per person per leg.
  • Visas and travel authorisations for Kenya and Tanzania.
  • Hot air balloon flight: roughly US$550–750 per person.
  • Travel insurance with medical evacuation cover, which is essential because camps are remote.
  • Tips for guides and camp staff: as a rule of thumb, around US$20–30 per day from your group for your guide and US$10–15 per guest per day for camp staff.

How to save money on a Great Migration safari

First, travel in the shoulder months. Late May, June, late October and early December offer excellent migration viewing at lower prices. Second, mix camp levels. Spend your "big" budget in the prime migration area, and choose a comfortable lodge elsewhere. Third, consider a drive-in safari for part of the trip. Finally, book early. The best-value camps in the right locations sell out first, and late bookers often end up paying more for a worse position.

What is included in a Paramount Great Migration safari?

Our quotes are fully transparent. They typically include all accommodation, meals on safari, a private vehicle and specialist guide, park and conservation fees, airport transfers and internal flights where listed. We show optional extras, such as balloon flights, separately so you can choose.

Combine the Great Migration with Gorillas and Beaches

This is where Paramount Gorilla Expeditions stands apart. Our home is Uganda, and our team works across Kenya, Tanzania, Zanzibar and the Seychelles. As a result, we can link the Great Migration with Africa's other great experiences in one smooth journey.

Great Migration + mountain gorilla trekking

Seeing the herds and then sitting an hour with a family of mountain gorillas is the ultimate East African combination. Uganda's Bwindi Impenetrable Forest is a short flight from Nairobi via Entebbe. Gorilla trekking runs all year, so it pairs well with any migration month. It works especially well with a Maasai Mara stay from July to October. Learn more about mountain gorilla trekking with our Uganda-based team.

Great Migration + Zanzibar

Zanzibar is the classic "bush and beach" partner for a Serengeti safari. Flights from the Serengeti airstrips or Arusha take about two to three hours, sometimes with a stop. Zanzibar's dry seasons also line up nicely with calving season and crossing season. Explore our Zanzibar travel guide.

Great Migration + Seychelles

For a more exclusive island escape, the Seychelles are a short flight from Nairobi. They are perfect for honeymooners who want white sand, granite boulders and quiet luxury after the dust of the plains. Read our guide to the perfect post-safari Seychelles escape.

A Great Migration honeymoon

The Great Migration makes an unforgettable honeymoon. Imagine private sundowners while the herds graze below you, then dinner by lantern light in your own tent. After that, you swap the plains for a quiet beach. For couples, we especially like February in Ndutu or September in the northern Serengeti, because both months combine great wildlife with dry weather on the coast. Moreover, many camps offer special touches for newlyweds, such as private dining and bush baths. Our Tanzania & Zanzibar Beach Week brings all of this together.

Great Migration + more of Kenya or Tanzania

In Kenya, add Amboseli for elephants beneath Kilimanjaro, or Samburu for rare northern species. In Tanzania, add the Ngorongoro Crater, Tarangire or Lake Manyara. Visit our Kenya safari guide and Tanzania safari guide for ideas.

Chapter 17

Planning Your Great Migration Safari: Practical Guide

In short, good planning turns a good safari into a great one. This chapter covers the practical details: how to get there, visas, health, packing and when to book.

How to get to the Great Migration

For Kenya, fly into Jomo Kenyatta International Airport (NBO) in Nairobi. From Nairobi's Wilson Airport, scheduled light aircraft reach the Maasai Mara airstrips in about 45 to 60 minutes. Alternatively, you can drive in five to six hours with a stop at the Great Rift Valley viewpoint.

For Tanzania, fly into Kilimanjaro International Airport (JRO). From there, or from Arusha Airport, light aircraft fly to Serengeti airstrips such as Seronera, Ndutu, Kogatende and Lamai. Flights take about one to two and a half hours, depending on the route and stops. Many travellers drive instead, visiting Tarangire and the Ngorongoro Crater on the way.

Visas and entry requirements

  • Tanzania: most visitors need a visa. Apply online through the official Tanzania e-visa portal. A single-entry visa usually costs US$50, while US citizens pay US$100 for a multiple-entry visa.
  • Kenya: most visitors need an Electronic Travel Authorisation (eTA) before departure, including children. Apply on the official Kenya eTA website. Processing takes up to three working days, so apply early.
  • Passport: it should be valid for at least six months after your departure date, with blank pages for stamps.
  • East Africa Tourist Visa: this covers Kenya, Uganda and Rwanda; however, it does not cover Tanzania.

Entry rules change often. Always check the official government websites before you travel, and we will remind you in your pre-departure pack.

Health and vaccinations

First, visit a travel clinic six to eight weeks before your trip. The Serengeti and the Maasai Mara are malaria areas, so doctors usually recommend anti-malaria tablets. In addition, Tanzania may ask for a yellow fever certificate if you arrive from, or transit for more than 12 hours through, a country with a risk of yellow fever. Kenya is on that list. So if you combine the two countries, it is wise to carry a valid certificate. Routine vaccines should also be up to date.

What to pack for a Great Migration safari

Clothing

  • Neutral colours: khaki, olive, beige and brown
  • Avoid dark blue and black, which attract tsetse flies in some areas
  • Warm fleece or jacket, because early mornings are chilly
  • Wide-brimmed hat and sunglasses
  • Comfortable closed shoes and sandals for camp

Essentials

  • Binoculars — one pair per person if possible
  • High-factor sunscreen and insect repellent
  • Power bank and universal adaptor
  • Personal medication and a small first-aid kit
  • A soft duffel bag for light-aircraft flights

Light aircraft usually limit luggage to around 15 kg per person, including hand luggage, in a soft bag. Also note that Kenya and Tanzania have banned plastic carrier bags. Pack your items in fabric or zip-lock alternatives instead.

Is a Great Migration safari safe?

Yes, for travellers who follow their guide's advice. The Serengeti and the Maasai Mara are well-established safari destinations. Your guide handles the driving and wildlife encounters. In camp, staff escort guests after dark, because wild animals move freely through unfenced camps. The main risks are sunburn, dehydration and bumpy roads, all of which are easy to manage.

Is the Great Migration good for families?

Absolutely. Children love the sheer number of animals. However, some camps set minimum ages, often 6, 8 or 12 years, and long game drives can be tiring for young kids. We recommend family-friendly camps with pools, shorter drives and a private vehicle, so you set the pace. Explore our family safari experiences for more ideas.

How to choose the right Great Migration safari operator

Your operator shapes every part of the trip, so it pays to ask the right questions. First, ask where they will place you in your travel month, and why. A good specialist explains the herd's likely position and offers a backup plan. Second, check who your guide will be. Experience with the migration matters far more than a smart vehicle.

Next, ask whether you get a private vehicle. Shared vehicles cost less; however, they limit how long you can wait at a crossing. In addition, check that park fees, flights and transfers are clearly included in the quote. Finally, look for a licensed company with verified reviews and people on the ground in each country you visit. In short, choose local knowledge, clear pricing and honest advice.

When should you book?

Responsible Travel and the Future of the Great Migration

The Great Migration has survived for thousands of years. Yet it now faces real pressure. As travellers, we can be part of the problem or part of the solution. At Paramount, we choose the solution, and we invite you to join us.

The threats facing the migration

  • Habitat loss and fencing: farming and settlement around the ecosystem's edges shrink the land available to the herds, especially in Kenya's Loita Plains.
  • Pressure on the Mara River: deforestation in the Mau Forest and water extraction upstream reduce dry-season flows, so the river runs lower when the herds need it most.
  • Infrastructure: a plan for a paved highway across the northern Serengeti was blocked by the East African Court of Justice in 2014, but development pressure continues.
  • Climate variability: changes in rainfall affect grass growth and, therefore, the timing of movements.
  • Overcrowding: too many vehicles at crossing points stress animals and, as a result, can even stop crossings.

How your safari can help

First, stay in camps that support conservation and local communities. The Mara conservancy model, for example, pays Maasai landowners to keep their land open for wildlife. Second, choose a responsible operator whose guides respect crossing rules. Third, pay your park fees gladly. They fund rangers, research and anti-poaching work. Finally, spread your visit across the year. Travelling in the shoulder months reduces pressure during peak season, and it often gives you a better experience too.

Great Migration Myths vs Facts

Unfortunately, plenty of misleading information circulates online. Here are the most common myths we hear, and the facts behind them.

MythFact
"The Great Migration happens in Kenya."The herds spend most of the year in Tanzania. They are usually in Kenya only from about July to October.
"The migration is one event in July."It is a year-round loop. Every month offers something special.
"The herds cross the Mara River once."They cross many times, in both directions, over several months.
"A river crossing is guaranteed in August."Crossings are likely but never guaranteed. Time and patience improve your odds.
"The wet season is a waste of time."The green season brings calving, lush scenery, fewer crowds and lower prices.
"Two million wildebeest take part."Aerial surveys estimate about 1.3 million wildebeest, and a 2025 satellite study suggests it may be fewer. The larger figures include zebra and gazelle.
"You need a huge budget."Comfort-level safaris and smart timing make the Great Migration more affordable than many people expect.

Key Takeaways: Planning the Perfect Great Migration Safari

Let us bring it all together. The Great Migration is not a single moment but a year-long journey, and every season offers something different. Use these key points to plan your trip with confidence.

  • Pick your priority first. Calving and cats point to February in Ndutu. River crossings point to August or September in the north.
  • Choose the area, then the camp. Being close to the herds matters more than a fancy room.
  • Stay longer in fewer places. Four nights in the right area beats two nights in three places.
  • Consider both countries from July to October to double your crossing chances.
  • Book early for peak months, because the best-positioned camps sell out first.
  • Travel responsibly. Respect crossing rules and support conservancies that benefit local communities.

Above all, travel with people who know the herds. The Great Migration rewards patience, local knowledge and flexibility. With the right plan, it will be the wildlife experience of your life.

Chapter 21

Great Migration FAQs

Here are quick answers to the questions travellers ask us most often about the Great Migration.

What is the Great Migration?

The Great Migration is the annual, circular journey of the Serengeti's wildebeest, together with zebra, gazelle and eland, through Tanzania's Serengeti and Kenya's Maasai Mara. The herds follow the rain and fresh grass in a loop of roughly 800 to 1,000 kilometres. It is the largest overland mammal migration left on Earth, and it continues all year.

When is the best time to see the Great Migration?

It depends on what you want to see. February is best for the calving season and big-cat action in the southern Serengeti. August and September are best for Mara River crossings in the northern Serengeti and the Maasai Mara. June is ideal for Grumeti River crossings in the Western Corridor. There is no bad month, only a different experience.

Where is the Great Migration each month?

In a typical year, the herds are in the southern Serengeti and Ndutu from December to March. They move through central Serengeti in April and May, and into the Western Corridor in May and June. From July to October, they are in the northern Serengeti and the Maasai Mara. In November, they return south along the eastern side of the park.

Is the Great Migration in Kenya or Tanzania?

Both. However, the herds spend most of the year, roughly nine months, in Tanzania's Serengeti ecosystem. They are usually in Kenya's Maasai Mara from about July to October. The animals cross the border freely, because the Serengeti and the Mara form one connected ecosystem.

How many animals take part in the Great Migration?

Long-running aerial surveys estimate about 1.3 million wildebeest, plus roughly 200,000 zebra and several hundred thousand gazelle. In 2025, however, an Oxford-led satellite study counted far fewer wildebeest in parts of the ecosystem. Scientists are still debating the true figure, so treat any single number with caution.

When do the Mara River crossings happen?

Mara River crossings usually happen between July and October, with August and September being the most reliable months. The herds cross many times and in both directions. The exact timing depends on rainfall and grazing, so the first crossings can come as early as late June in some years.

Is a Mara River crossing guaranteed?

No. Crossings are wild events, and nobody can guarantee one. However, you can greatly improve your chances. Stay at least four nights near the river in August or September, take full-day game drives, and travel with an experienced guide who reads herd behaviour and shares sightings by radio.

When is the Great Migration calving season?

Calving season usually runs from late January to March, peaking in February. It takes place on the short-grass plains of the southern Serengeti and the Ndutu area. At the peak, around 8,000 calves may be born each day, which attracts lions, cheetahs and hyenas.

How much does a Great Migration safari cost?

Roughly, expect about US$350 to US$750 per person per night for a comfort-level safari, US$550 to US$1,300 for a premium safari, and US$900 to more than US$2,500 at top luxury camps. Prices include accommodation, meals, a private guide and park fees. Costs are highest from July to October and over Christmas.

How many days do I need for a Great Migration safari?

We recommend at least four nights in the main migration area, plus time to travel. A seven- to ten-day safari lets you see the herds and add places such as the Ngorongoro Crater or Tarangire. If you want both sides of the Mara River, plan ten to twelve days.

Can I combine the Great Migration with gorilla trekking?

Yes. It is one of our most popular combinations. You can fly from Nairobi to Entebbe and continue to Uganda's Bwindi Impenetrable Forest for mountain gorilla trekking. This pairs especially well with a Maasai Mara safari from July to October. Gorilla trekking runs all year.

Is the Serengeti or the Masai Mara better for the Great Migration?

The Serengeti is better for most of the year, including calving season and the Grumeti crossings. The Maasai Mara is excellent from July to October, with short flights from Nairobi and superb private conservancies. In peak crossing months, combining both gives you the best chance of seeing the action.

Is the Great Migration worth seeing in the rainy season?

Yes. The green season from November to May brings calving, newborn animals, lush landscapes, migratory birds, fewer vehicles and lower prices. Rain usually falls as short afternoon storms. Only April and early May are very wet, and even then the resident wildlife of central Serengeti is excellent.

How far do the wildebeest travel during the Great Migration?

The annual loop covers roughly 800 to 1,000 kilometres. However, individual animals walk much further, because they wander back and forth in search of grass and water. Some studies of collared wildebeest suggest they can cover well over 1,000 kilometres a year.

Can I see the Great Migration on a budget?

Yes. Travel in the shoulder or green season, choose comfortable rather than luxury camps, and consider a drive-in safari for part of the trip. Late May, June, November and early December offer good migration viewing at lower rates. Booking early also secures the best-value camps in the right areas.

How far in advance should I book a Great Migration safari?

For July to September and for February, book nine to twelve months ahead. The best camps near the crossing points and in the calving zone sell out early. For green-season travel, three to six months is usually enough. Early booking matters more than perfect dates.
