Lake Kivu: Things to Do, Methane Facts, Congo Nile Trail and Travel Guide

Written by the Paramount Gorilla Expeditions guiding team · Last updated 31 October 2026

Lake Kivu is Rwanda's largest lake, a deep, mountain-ringed freshwater lake on the border with the Democratic Republic of Congo, with a shoreline of beaches, pine hills, islands and small lakeside towns that makes the best place in the country to rest after gorilla trekking. It is also one of the most unusual lakes in the world, because its deep water holds huge amounts of dissolved methane and carbon dioxide, which Rwanda now uses to make electricity. This guide explains what Lake Kivu is, the truth about the gas, the three main towns, the activities from boat trips to the Congo Nile Trail, where to stay, how to get there and what to know about the border. People also search for the same lake as Lake Kivu Rwanda, things to do at Lake Kivu, Gisenyi and Rubavu beach, Kibuye and Karongi, Cyangugu and Rusizi, Napoleon Island, Lake Kivu methane gas and Lake Kivu after gorilla trekking.

Quick answer

What is Lake Kivu known for? Lake Kivu is known for its scenery, its beach towns of Rubavu, Karongi and Rusizi, its islands, the 227-kilometre Congo Nile Trail along its shore and the methane in its deep water, which is extracted to generate electricity. It covers about 2,700 square kilometres and lies at about 1,460 metres above sea level on the border with the Democratic Republic of Congo. Visitors usually stay two or three nights, often after gorilla trekking in Volcanoes National Park.

Lake Kivu at a glance

Chapter 01 — What is Lake Kivu?

Lake Kivu sits in the Albertine Rift, the western arm of the East African Rift Valley, and it forms part of the border between Rwanda and the Democratic Republic of Congo. It is about 2,700 square kilometres in area, roughly 1,460 metres above sea level and about 475 metres deep at its deepest point, which makes it one of the deepest lakes in Africa. It is Rwanda's largest lake, and Visit Rwanda counts it among the largest on the continent.

The lake's shape and setting come from the rift. Steep green hills drop to the water, and the shoreline is a series of bays, peninsulas and headlands, with small islands scattered along it. The Virunga volcanoes, which you pass if you are coming from Volcanoes National Park, lie at the northern end, and their lava flows long ago blocked the lake's outlet to the north, so that the water now drains south through the Ruzizi River into Lake Tanganyika. The climate is mild and pleasant, with cool mornings and warm afternoons. Our Rwanda destination page shows how the lake fits between the volcanoes and Nyungwe.

Chapter 02 — The truth about the methane and the "exploding lake"

Lake Kivu is one of only three lakes in the world known to hold large amounts of gas dissolved in their deep water, and it is the one that makes the headlines. The deep water of Kivu holds an estimated 65 cubic kilometres of methane and more than 250 cubic kilometres of carbon dioxide, both produced by volcanic activity and by the decay of organic matter at the bottom. The gas is held in the water by pressure, in the same way that fizz is held in a sealed bottle.

The danger comes from what is called a limnic eruption, in which a sudden disturbance releases the gas. It has happened before in other lakes: Lake Monoun in Cameroon in 1984, which killed 37 people, and Lake Nyos in Cameroon in 1986, where a cloud of carbon dioxide killed about 1,700 people and thousands of animals. About two million people live in the Lake Kivu basin, which is why the lake is studied so closely.

Here is what you need to know as a visitor. First, the gas is dissolved deep in the water, hundreds of metres below the surface, and swimming, boating and walking along the shore are not affected. Second, the risk is a long-term hazard that scientists monitor, not an event that can be predicted for tomorrow, and anyone who says the lake will explode soon is not reading the science. Third, Rwanda has been extracting the methane for power, which also lowers the amount of gas in the deep water. A lake that can be used for electricity and for holidays at the same time is not a lake that visitors need to fear, and the thousands of people who live and work on its shore carry on as normal.

Chapter 03 — Methane power: KivuWatt

The methane in Lake Kivu is a resource as well as a risk. KivuWatt, a plant built and run by KivuWatt Limited, a subsidiary of the energy company ContourGlobal, is at Kibuye, in Karongi District, about 130 kilometres west of Kigali. It has a capacity of about 26 megawatts and was inaugurated in 2016, and its power is bought by the Rwandan national energy utility. The plant draws gas-rich water from the deep lake, separates the methane from it and returns the treated water to the lake.

More extraction is planned, though the schedule for additional phases has changed over the years. For a visitor, the plant is mostly out of sight, and it is a reminder that Rwanda is making use of a rare natural feature. Do not try to enter the site; visits are not part of the standard visitor offer.

Chapter 04 — The three main towns: Rubavu, Karongi and Rusizi

Rwanda's shore has three main towns, and they feel very different from one another.

For most visitors, Rubavu or Karongi is the right base. Rubavu is the easiest to reach from Volcanoes and has the most choice of places to stay, and Karongi is calmer, with the better boat trips. Rusizi is useful as a gateway to Nyungwe National Park, which we cover in our Nyungwe guide. Nyungwe was added to the UNESCO World Heritage List on 19 September 2023.

Chapter 05 — Boat trips and the islands

A boat trip is the best way to see the lake. From Karongi, motorboats run to several islands, and a half-day trip is enough to see the main ones. Napoleon Island, whose local name is Nyamunini, is a small forested island that is known for the colony of fruit bats that roost in its trees, and they fly out at dusk. Amahoro Island and Iwawa are other small islands that boat operators visit. Nkombo, the largest island on the Rwandan side of the lake, has its own local culture and can be visited with a guide.

Boats are generally small and open, so ask your lodge to arrange a reputable operator, check the weather and the life jackets before you go, and avoid any area that the authorities have restricted. Kayaking tours are also offered on the lake, and a morning paddle is a good way to see the shoreline in the calm. Most lodges can arrange a sunset cruise.

Chapter 06 — Swimming, beaches and health

The beaches at Rubavu and Karongi are the best places to swim, and many lodges have their own small beaches and docks. The gas problem described above is confined to the deep water and does not affect swimming at the surface. What deserves thought is the usual question about freshwater in East Africa: bilharzia, a disease carried by snails that live in shallow, still freshwater.

We cannot give medical advice, and we cannot promise any freshwater is free of the snails. Ask your lodge where local people swim, ask a travel clinic about bilharzia before you travel, and use a pool if you prefer. Our malaria and vaccinations guide covers the health checks to make before a trip. Drink only sealed or properly treated water, and use sunscreen, because the altitude and the water make the sun stronger than it feels.

Chapter 07 — Fishermen, isambaza and local food

One of the sights of the lake is the fishermen. At dawn and dusk, wooden boats with long outriggers head out onto the water, and the fishermen sing as they paddle, a tradition you can hear from the shore. Many of the boats work at night, with lamps to attract the small fish that they catch.

The fish at the centre of this is the isambaza, a small sardine whose scientific name is Limnothrissa miodon. It was introduced to the lake in the late 1950s, and it is now a mainstay of the local fishery and of the local menu, where it is usually fried until crisp and eaten with a cold drink. Tilapia is the other common fish. Our East African food guide explains what to try and what to ask about.

Chapter 08 — Coffee on the lake shore

The hills around Lake Kivu are coffee country, and the shore is one of the best places in Rwanda to see how coffee is grown and washed. Villages such as Kinunu, on the trail, have cooperatives where visitors can follow the process from seedlings to processing and buy packaged coffee. Visits are best arranged through a guide, because not every farm is open to visitors, and the harvest runs from about March to June.

A coffee stop fits well into a day on the Congo Nile Trail or a drive along the shore, and it gives you a chance to meet the people who grow it. Our Kigali travel guide covers the specialty coffee scene in the capital.

Chapter 09 — The Congo Nile Trail

The Congo Nile Trail follows the Rwandan shore of Lake Kivu for about 227 kilometres, from Rubavu in the north to Rusizi in the south. It takes its name from the watershed between the Congo and Nile river basins, which runs along the ridge above the lake. The route follows dirt roads, village tracks and some tarmac, with steep climbs and descents, and it passes tea and coffee estates, villages, forests and viewpoints.

Operators divide the trail in different ways. Cyclists usually allow five to eight days, with a bike suited to dirt roads, and hikers usually allow ten days or choose sections of a day or two. Some sections include a boat ride, and parts can be done by 4x4 or motorbike. The longest and steepest days are on the central section, and the surface is rough and can be muddy after rain, so a narrow road bike is not suitable.

The best months are the dry months from June to September, and December to February can also be good. The wetter months are roughly March to May and October to November, and some river crossings become difficult in the rains. Most visitors book a guide, bike hire and a luggage transfer, which makes the trip much easier. Check the border advice below, because it can affect the start and finish. Our cycling safari guide covers cycling in the region.

Chapter 10 — The border with DR Congo and what to know about safety

The Democratic Republic of Congo lies directly across the lake, and the Congolese shore, including Goma and Bukavu, has been affected by armed conflict since early 2025. Several governments advise against travel in parts of Rubavu and Rusizi districts close to the border, and some advise against all but essential travel within about 10 kilometres of it. The advice changes, and it can affect travel insurance as well as your route.

We do not plan crossings into the Democratic Republic of Congo, and we plan Rwandan stays on the Rwandan side of the lake with this in mind: a base at Karongi, or at a part of Rubavu away from the border, is easier to plan than one next to the crossing. Check your own government's advice shortly before you travel, and ask us what we know about the area on your dates. Our guides to whether East Africa is safe to visit and to safari travel insurance explain how we approach risk and cover.

Chapter 11 — Getting to Lake Kivu

From Kigali, Rubavu is about 164 kilometres by road, a drive of about three and a half hours in normal traffic, and Karongi is about 130 kilometres, a drive of about three hours. Rusizi is further south and takes much longer, so most travellers reach it from Nyungwe. From Volcanoes National Park, Rubavu is about an hour's drive, which makes the lake an easy next stop after gorillas.

The roads are good for most of the way, but they twist through hills, so allow more time than the distance suggests, and avoid driving after dark. Our Kigali travel guide covers the starting point, and our Volcanoes National Park guide covers the gorilla trek that many visitors do first.

Chapter 12 — Where to stay at Lake Kivu

We name the type of stay and the town, and your written quote lists the lodge, the rate and the transfer. Because lodges change owners, standards and prices often, we choose them for your dates.

• Luxury: lakeside lodges at Karongi or Rubavu. Rooms with lake views, private jetties and spa treatments. Verdict: the best choice for a recovery stay after gorillas.
• Mid-range: lakeside hotels at Rubavu and Karongi. Comfortable rooms, a restaurant and a beach or dock. Verdict: the best balance for most travellers.
• Budget: guesthouses and hostels in Rubavu and Karongi. Simple rooms in town or on the shore. Verdict: good value for the Congo Nile Trail and for backpackers.
• On the trail: base camps. Simple lodgings in villages along the route, sometimes with camping. Verdict: for walkers and cyclists, booked with the trail.

If you have time for only one base, choose Karongi for calm and boat trips, and choose Rubavu if you want more restaurants, beaches and an easier link to Volcanoes.

Chapter 13 — Best time to visit Lake Kivu

The dry months, from June to September, give the clearest skies and the most reliable weather for boat trips and the Congo Nile Trail. December to February is a second, shorter dry period. The wetter months, roughly March to May and October to November, bring cloud and rain, with April the wettest, and the roads and trails are slower.

The lake is pleasant all year, because the altitude keeps the temperature mild, and the wet months are green and quiet. If you want sunshine for a beach stay after gorillas, choose a dry month. Our Rwanda national parks comparison gives the season for each of the three parks.

Chapter 14 — How Lake Kivu fits into a Rwanda trip

Lake Kivu is best as a pause between the volcanoes and the forest. A typical route runs from Kigali to Volcanoes for gorillas, then down to Rubavu for a rest, along the shore to Karongi for the boat trips, and south to Nyungwe for chimpanzees, before returning to Kigali. It can also be added to a Rwanda and Uganda trip by crossing the border near Kisoro and driving to Rubavu.

Four days. Volcanoes for gorillas, then two nights at the lake.

Seven days. Kigali, Volcanoes, two nights at Rubavu or Karongi, Nyungwe and back to Kigali. See our 7-day complete Rwanda primates tour for a ready-made option, and our 5-day Rwanda gorilla and golden monkey tour.

Ten days with savannah. Add Akagera at the start or end, for the Big Five. See our Akagera National Park guide. Our Rwanda safari packages and Rwanda safari cost guide give the prices.

Chapter 15 — Lake Kivu or Lake Bunyonyi?

Many travellers combining Rwanda and Uganda ask which lake to choose. The answer depends on what you want from the stay.

Our Lake Bunyonyi guide covers the Ugandan lake in detail. You do not have to choose: on a combined trip, spend a night at Bunyonyi after Bwindi, and two at Kivu after Volcanoes. Our guide to combining Uganda and Rwanda gorilla trekking explains the route.

Chapter 16 — Memorials and culture on the lake shore

The shore is not only scenery. Karongi has a small museum of the environment, and the district is home to Bisesero, one of the four genocide memorial sites in Rwanda's UNESCO World Heritage listing, which was inscribed in 2023. Bisesero tells the story of the people who resisted the genocide in the hills above the lake, and it is a place for a quiet, respectful visit with a guide, not for a rushed stop.

Plan this the way you would plan the visit to the Kigali Genocide Memorial, with time to reflect afterwards. We cover the capital's memorial in our Kigali travel guide. Rwanda's conservation story has a more hopeful side, too, in the annual naming of baby gorillas; see Kwita Izina.

Chapter 17 — Tips from our guides

1. Choose a base away from the border if you are unsure, and check your government's advice.
2. Allow two or three nights. One night is too short for the drive.
3. Take a sunset boat trip. The light on the water is the best of the day.
4. Ask your lodge where people swim, and ask a travel clinic about bilharzia.
5. Do not worry about the gas. It is deep, monitored and being used for power.
6. Book a guide for the Congo Nile Trail, and a luggage transfer.
7. Pack for rain, even in the dry months.
8. Carry cash. Card use outside the hotels is limited.
9. Drive in daylight. The hill roads are slow and winding.
10. Try isambaza and the fresh tilapia.
11. Visit Bisesero with a guide and give it time.
12. Ask us to plan it. We confirm the lodge, boats and transfers on your written quote.

Chapter 18 — Myths about Lake Kivu

• "Lake Kivu could explode tomorrow." The gas is a long-term hazard that scientists monitor and that is being extracted; no one can predict a date, and visitors are not at risk at the surface.
• "It is unsafe to swim because of the gas." The gas is hundreds of metres down. Swimming at the surface is not affected by it.
• "You can cross into Goma easily." Conditions on the Congolese side have been affected by conflict, and we do not plan crossings.
• "Lake Kivu is just a beach." It also has islands, coffee, memorials and a 227-kilometre trail.
• "You need a week." Two or three nights is enough for most travellers.
• "The lake is dead because of the gas." It has a fishery and a long-established fishing culture.

Our verdict

Lake Kivu is the best place in Rwanda to slow down. It is a large, scenic lake with beach towns, islands, coffee villages and a long trail, and the gas that makes the headlines is deep, studied and put to use. Choose Karongi for calm or Rubavu for convenience, give it two or three nights after gorillas, keep an eye on the border advice and travel in a dry month. Tell us your dates and your route, and we will plan the stay and confirm the lodge, boats and transfers on your written quote.
