Lake Bunyonyi Uganda: Depth, Islands, Where to Stay and How to Visit

By Anita Kesande, Safari Expert at Paramount Gorilla Expeditions · Last updated 31 October 2026

Lake Bunyonyi in south-western Uganda is the place most travellers stop to breathe out after gorilla trekking: a deep, terraced, island-dotted lake about 7 km from Kabale town, high in Kigezi at roughly 1,960 metres. People also search for it as Bunyonyi Lake, Lake Bunyonyi Uganda or "the place of many little birds", which is what the name is usually translated to mean. This guide answers the questions travellers actually ask about it: how deep it really is, how many islands there are, what Punishment Island was, whether you can swim, where to stay and how to fit a night or two around Bwindi, Mgahinga and the Rwanda border.

Quick answer

Lake Bunyonyi is a freshwater lake in Kabale District, south-western Uganda, formed when lava from the nearby Virunga volcanoes dammed a river valley. It covers about 46 km² and lies roughly 7 km west of Kabale. Published lake studies give a maximum depth of about 40 metres, not the 900 metres often repeated in tourist material. About 29 islands are usually counted.

It suits travellers who want a slow, scenic, low-effort stop between gorilla treks or before crossing into Rwanda. One night is the minimum, two nights is the sweet spot, and three is for birders and walkers. Fit it in after trekking, not before, so tired legs get the lake and the hammock.

Lake Bunyonyi at a glance

Chapter 01 — Where is Lake Bunyonyi and what is it?

Where is Lake Bunyonyi? Lake Bunyonyi is in the far south-west of Uganda, in Kabale District, a short drive from the town of Kabale and not far from the borders with Rwanda and the Democratic Republic of the Congo. It sits among steep, intensively farmed hills in the Kigezi highlands, close to Bwindi Impenetrable National Park and Mgahinga Gorilla National Park.

The lake is long and narrow, with many arms and bays, which is why it looks like several lakes from the shore. Farmed terraces climb the hills on every side, and the islands sit in the middle like small green hats. The water is cool, the air is cooler than most of Uganda and mornings often start in mist. Kabale town, the usual gateway, is at about 2,000 metres.

The name Bunyonyi is usually translated as "place of many little birds". A folk account says the Bakiga named it because the lake was so wide that small birds could not cross it. Treat that as oral tradition rather than a language source, but it explains why the name stuck and why birdwatchers love the place.

Chapter 02 — How Lake Bunyonyi formed

Lake Bunyonyi is a dammed-valley lake. Volcanic activity in the Virunga range sent lava across a river valley near the village of Muko, which blocked the river and let the water back up into the many arms you see today. That is why the shoreline is so crooked and why the lake has only a small outlet near Muko rather than rivers running out of it.

Published accounts date the event to somewhere between about 10,000 and 18,000 years ago, and the sources do not agree on a single figure. The practical point for a visitor is this: the lake is geologically young, volcanic in origin and part of the same highland landscape as the Virunga volcanoes you can see on a clear morning from the Kisoro side.

Chapter 03 — How deep is Lake Bunyonyi? The 40-metre answer

How deep is Lake Bunyonyi? Scientific studies of the lake give a maximum depth of about 40 metres (roughly 130 feet). The popular claim that it is about 900 metres deep, or "the second deepest lake in Africa", comes from tourist guides and local retelling, not from published depth surveys. A lake that deep would also be far deeper than Lake Edward, which is given as 112 metres.

This is the single most repeated error about Bunyonyi, and it is worth knowing why it is wrong:

• The measured figure is about 40 m. Published limnological work on Bunyonyi, including studies from 1962, 1972, 2009 and 2016, gives a maximum depth of around 40 metres.
• The 900 figure is not measured. It appears in tourist literature and local conversation. Some sources give it in feet rather than metres, which is a different number again, and one popular version gives a lower bound of 44 metres.
• The comparison fails. Lake Edward, a large rift valley lake shared with the Democratic Republic of the Congo, is given as 112 metres at its deepest. A 900-metre Bunyonyi would be a world-class deep lake, and it is not on any list of the world's deepest lakes.

None of this makes the lake less impressive. A 40-metre-deep lake with 29 islands, no big outflow and volcanic origins is a remarkable thing to float on. When your guide says 900 metres, smile and enjoy the story, then keep the real number for your own notes.

Chapter 04 — How many islands are there in Lake Bunyonyi?

How many islands are in Lake Bunyonyi? About 29 islands are usually counted: five separate sources, including a Uganda Tourism Board portal page, give 29. Some operators write "20-plus islands", so you will see different numbers. The islands vary from tiny rock and papyrus outcrops to larger inhabited ones with schools, farms and lodges.

The islands that travellers hear about most are these.

Akampene, also called Punishment Island

What is Punishment Island? Akampene, usually called Punishment Island in English, is a tiny island in Lake Bunyonyi where, according to oral accounts, unmarried girls who became pregnant were left to starve or drown. It is also said that a man without cattle could take such a girl as a wife by paddling out to collect her. The practice is described as having ended in the first half of the twentieth century.

Several details are worth stating carefully. The accounts come from oral history, journalism and operator guides rather than from an archival record, so there are no reliable figures for how many girls were left there. Sources differ on when the practice ended. The island itself is now very small: a few trees and a patch of grass, and local elders say it was once much larger. Visitors usually see it from a canoe or boat without landing.

Treat the place with respect. It marks a harsh part of Bakiga history, and guides tell the story best when visitors listen first and photograph second.

Bwama Island and the leprosy colony

Bwama Island is the best-documented island on the lake. A British missionary doctor, Dr Leonard Sharp, arrived in Kigezi in 1921 and, according to a 2026 conference abstract in the British Journal of Dermatology, a leprosy colony opened on Bwama in 1931 with 25 patients. It grew to about 300 by 1933. The colony closed in the 1980s. Today Bwama is home to a school, a dispensary and a small hospital.

This is one of the lake's real stories and one of the reasons the island is worth a visit with a local guide. It is a very different story from Punishment Island, and Bwama is a place of work, school and recovery rather than shame.

Itambira, Njuyeera, Bushara and the rest

Itambira lies next to Bwama and is reached by the same short boat or canoe trip. Njuyeera is another island linked to the missionary period. Bushara and Kyahugye appear in published lists of the lake's islands. Some of the larger islands now have lodges, camps or small farms, and several have schools. A day of island hopping usually combines two or three of them.

Chapter 05 — The Bakiga: people and culture around the lake

The Bakiga are the dominant people around Lake Bunyonyi, and the hills here are some of the most intensively terraced in Uganda. The Uganda Wildlife Authority describes the Bakiga as known for their rich traditions and storytelling, and that is the best way to meet them: by listening, walking through villages with a local guide and visiting a community project rather than ticking off a "cultural show".

A few facts help make sense of what you see:

• The terraces are the culture. Farming on steep slopes in cool, wet hills shaped how people lived, and the terraced hillsides are the most visible result.
• Kabale means small stone. The name of the main town comes from the Rukiga word for a small stone.
• Blacksmithing and iron history. A Uganda Tourism Board portal page notes iron smelting in villages around the lake, including Bukora, home of the Bahesi clan.
• The Batwa. The Batwa are the forest people of the region. Many were removed from forests such as Echuya after protected areas were declared. Community experiences led by Batwa can be part of a Kigezi trip when they are run by the community itself.

If you want a cultural visit, ask us to arrange one that is run by the community and pays the community directly, rather than a staged show. We build these into the route when we plan the trip.

Chapter 06 — Things to do at Lake Bunyonyi

The best things to do at Lake Bunyonyi are slow ones, and that is the point.

• Canoe or dugout trip. The classic activity: a paddled dugout across calm water, with a guide who names the birds and the islands. Early morning is the quietest time.
• Motorboat island tour. Faster, so you can see Akampene, Bwama and Itambira in one outing and get back for lunch.
• Island hopping with a stop for lunch. Several islands have a lodge or camp where you can stop for a meal or a swim.
• Bird walks and boat birding. See Chapter 07.
• Hill walks and village walks. Footpaths run up and over the terraced ridges, with long views over the water. A half day is enough for most travellers, and a guide will turn it into a cultural visit.
• Sunrise and sunset on the water. The mist at dawn and the light at dusk are the reason many people extend by a night.
• A swim from your lodge's dock. See Chapter 08.
• A visit to the Bakiga Cultural Museum or a blacksmith's workshop. These are listed as stopovers around the lake.
• An easy day with no plan. Bunyonyi is one of the few places in a Uganda itinerary where doing nothing is the recommended activity.

Chapter 07 — Birding at Lake Bunyonyi

Birdwatching is the reason the lake is named as it is, and it is good without being strenuous. A Uganda Tourism Board portal page (2023) and several other sources put the number of recorded species at over 200, though no single checklist is cited, so treat the number as a guide.

What you can expect to see, from a canoe or along the shore:

• Grey crowned crane (Balearica regulorum), Uganda's national bird, stately on the shoreline and in farmland.
• Papyrus specialists in the reed beds: papyrus gonolek (Laniarius mufumbiri), papyrus canary (Crithagra koliensis) and papyrus yellow warbler (Calamonastides gracilirostris).
• Kingfishers and waterbirds: malachite kingfisher (Corythornis cristatus), pied kingfisher (Ceryle rudis), hadada ibis (Bostrychia hagedash) and herons and egrets along the edges.
• Raptors such as the African harrier-hawk (Polyboroides typus).

For forest birds and Albertine Rift endemics, combine the lake with Echuya Forest Reserve on the Kabale to Kisoro road, which is recorded as having 153 bird species of which 18 are endemic. For the bigger East African birding picture, including routes that link Uganda with Kenya and Tanzania, see our East Africa birding safari guide.

Chapter 08 — Is it safe to swim in Lake Bunyonyi?

Is Lake Bunyonyi safe to swim in? Lodges on the lake describe the water as free of bilharzia, crocodiles and hippos, and swimming from a lodge dock is the normal way to do it. Swim where the water is deep and clear rather than in reeds, never swim alone, and keep strong swimmers close with children. Take medical questions about water-borne illness to a travel clinic before you travel.

A few practical notes:

• The lake is cold and deep near the islands. At around 1,960 metres the water is cool, and a long swim tires people faster than expected.
• Use the dock, not the reeds. Lodge docks are the usual swimming points. Reed edges are where aquatic insects, snails and dead vegetation collect, on any East African lake.
• Water quality can change after heavy rain. In August 2025 heavy rain turned parts of the water brown, and the Ministry of Water and Environment attributed it to siltation and runoff, not volcanic activity. If the water looks cloudy or smells strongly after rain, skip the swim for a day.
• Do not drink the lake water. Use bottled or filtered water.

Chapter 09 — How to get to Lake Bunyonyi

The usual route is by road. From Kampala to Kabale is about 410 to 415 km of tarmac via Masaka and Mbarara, which the Uganda Wildlife Authority gives as roughly six hours of driving, and most travellers should plan for a full day with a lunch stop. From Kabale to the lake is a short, graded road of about 7 km.

By air. Many travellers fly from Entebbe to Kisoro or to the airstrips near Bwindi, then drive on to the lake, which saves most of the long Kampala road. We arrange this when time is short.

From Rwanda. Kigali to the lake via Katuna or Cyanika is a half-day journey including the border. For the border crossing itself, read our Uganda-Rwanda border crossing guide. The Cyanika crossing was closed to Ugandans by Rwanda in 2019, and border status changes, so we plan the crossing from current conditions when we build your route.

Chapter 10 — Where to stay at Lake Bunyonyi

There are three kinds of places to stay, and the choice shapes the whole visit.

• Island camps and lodges. You arrive by boat, everything is quiet, and the lake is at your door. These suit anyone who wants the lake as the main event.
• Mainland shoreline lodges. Easier to reach, often with terraced gardens and a dock, and a good fit for travellers on a tight schedule.
• Hotels in Kabale town. Convenient for an early start, but you lose the lake atmosphere. We use these only when timing demands it.

Which lodge is right depends on your route, your group and your budget, so we choose it when we build your itinerary and name it on your written quotation. Luxury lodges for gorilla trekking, which are usually the reason people are in Kigezi at all, are listed in our recommended lodges and camps, including Mount Gahinga Lodge near Mgahinga and Bwindi Lodge.

Chapter 11 — Lake Bunyonyi after gorilla trekking

Is Lake Bunyonyi worth visiting after gorilla trekking? Yes, and it is the standard rest stop. Gorilla treks are physically demanding, and the lake gives you a quiet day with no schedule between Bwindi or Mgahinga and the next leg. It is also on the main road between Kabale, Kisoro and the Rwanda border.

The logic works in three directions:

• Bwindi, Rushaga or Nkuringo, then the lake. The roads from the southern sectors reach the Kabale road through Kisoro, so the lake becomes a natural overnight on the way out.
• Mgahinga, then the lake. Mgahinga is near Kisoro, so the lake is a short transfer on the way back towards Kabale or the border.
• The lake, then Rwanda. Many travellers sleep at the lake, then cross at Katuna or Cyanika the next morning to trek gorillas in Rwanda's Volcanoes National Park.

For which Bwindi sector to choose, and how each is reached, see our Bwindi sector guide rather than this page, and for the second park see the Mgahinga Gorilla National Park guide. For a trip that uses both Uganda and Rwanda, read how to combine Uganda and Rwanda gorilla trekking.

Chapter 12 — Best time to visit Lake Bunyonyi

Lake Bunyonyi is a year-round destination, and the right month depends on what matters more to you: dry paths or fewer visitors.

• Drier months: roughly June to August and December to February. Paths are firmer, boat trips are more comfortable and the views are clearer.
• Rainier months: roughly March to May and September to November. The hills are greenest, there is more mist and the roads between Kabale, Kisoro and the gorilla sectors can be slippery.
• Temperature: cooler than most of Uganda because of the altitude. Pack a warm layer for mornings and evenings, and rain gear for any month.

Because the lake is usually combined with gorilla trekking, the better question is when to trek. Our best time to visit Uganda guide covers the seasons for the whole country.

Chapter 13 — What does a visit to Lake Bunyonyi cost?

We do not publish a single price for the lake because it depends on choices that vary more here than almost anywhere in Uganda. These are the items that set the cost, and who sets each one:

Everything is itemised on your written quotation, so you can see exactly what the lake adds to the trip. For what a whole Uganda safari costs, see our Uganda safari cost guide.

Chapter 14 — How Lake Bunyonyi fits into a Uganda itinerary

One night. Arrive from Bwindi or Mgahinga in the afternoon, take a short canoe trip before dark and leave after breakfast. This is the minimum that makes the transfer worthwhile.

Two nights. The sweet spot. A full day on the water and the hills with a proper rest, and a chance to see Akampene and Bwama without hurrying.

Three nights. For birders, walkers and anyone recovering from several long drives. Add Echuya Forest or a longer community visit.

Lake Bunyonyi is part of our 10 Days Best Of Uganda Safari, which covers Murchison Falls, Kibale, Queen Elizabeth, Bwindi, Lake Bunyonyi and Lake Mburo. For trips that cross into Rwanda from the lake, see the Uganda and Rwanda Double Gorilla Safari, and for all packages see our Uganda safari packages guide. For a bigger plan that takes in Murchison Falls and Queen Elizabeth, see the Uganda complete local guide.

Chapter 15 — Mistakes to avoid and local tips

1. Scheduling the lake before trekking. Put it after the gorillas, so you rest when your legs need it.
2. Repeating the 900-metre story. The measured depth is about 40 metres.
3. Squeezing it into a lunch stop. A two-hour visit shows you the view and none of the lake.
4. Planning to swim in the reeds. Use the dock.
5. Landing on Akampene for photos. Look from the water, listen to the story and be respectful.
6. Forgetting a warm layer. Mornings and evenings at this altitude are cool.
7. Skipping the guide. A local guide turns a boat ride into the history of the Bakiga and the islands.
8. Leaving the border to chance. Border conditions change, so plan crossings from current information on the day.
9. Trusting a single blog for distances. Road times in Kigezi vary with rain and roadworks, so build in slack.

Our verdict

Lake Bunyonyi is the best-value rest day in Uganda and the stop most travellers wish they had made longer. It rewards slowness. Come for the canoe at dawn, the island stories and the hills at sunset, and give it two nights. Do not come for the 900-metre depth: the real number is about 40 metres, and the lake is better for being honest.
