Gombe Stream National Park

Gombe Stream National Park is the smallest national park in Tanzania — a narrow, 35 km² ribbon of steep forested hills hugging the eastern shore of Lake Tanganyika, about 15 km north of Kigoma town. What it lacks in size it more than makes up for in story.

This is where, in July 1960, a young Jane Goodall began studying the wild chimpanzees of what was then the Gombe Stream Game Reserve. Her discoveries — that chimps make and use tools, hunt, and live in complex societies — transformed our understanding of our closest living relatives and rewrote a chapter of science.

Today Gombe remains the site of the longest-running study of wild chimpanzees in the world. Its famous Kasakela community is habituated to human visitors, and trekking through these forests to spend time with them is one of the most moving wildlife experiences anywhere in Africa.

Between the forest ridges and the clear, warm water below, the park packs remarkable diversity into a tiny area, typical of the chimpanzee destinations of Tanzania’s Western Circuit.

Gombe lies on the western rift escarpment, a series of steep valleys and forested ridges dropping from about 1,500 m down to the shore of Lake Tanganyika at 775 m. The park is a narrow band of habitat, roughly 12 km long and only a few kilometres wide, hemmed between the lake and the escarpment.

Streams such as the Kakombe tumble down the valleys to the lake, their courses clothed in riverine forest, while the upper slopes carry drier woodland. That range of habitats — from lake shore to ridgeline — explains why such a small park supports so much life.

Because the lake itself is one of the deepest and oldest in the world, its waters add an entirely separate ecosystem: clear, warm and packed with endemic fish that thrive just steps from the chimp trails.

The chimpanzees of Gombe are among the best-known wild animals on the planet. The Kasakela community has been followed for more than six decades, and its individuals — their personalities, rivalries and alliances — have been documented in books and films that reached audiences worldwide.

The chimps are habituated to people, so treks usually find them within a few hours. You may watch them feeding in the canopy, grooming one another or tumbling in play on the forest floor — behaviour startlingly familiar and profoundly humbling in equal measure.

Visits are strictly regulated to protect the animals. Groups are small, time with the chimps is limited, and anyone who is unwell must stay behind, because human illnesses can be dangerous to them.

Gombe’s fame rests on the work of Jane Goodall, who arrived in 1960 with no formal scientific training and enormous patience. Her first breakthrough — watching a chimp named David Greybeard fashion and use a tool to fish for termites — overturned the long-held belief that only humans made tools.

The research station she founded in 1965 continues to operate, and Gombe is now a national park, gazetted in 1968. The continuous observation of the same chimpanzee community is one of the longest-running field studies of any wild animal anywhere.

That scientific heritage is inseparable from a visit here. Trekking in Gombe is not only about seeing chimpanzees; it is about standing where a revolution in our understanding of animal minds began.

Gombe is small and visitor numbers are capped, so permits for chimpanzee trekking should be arranged well in advance. Entry, trekking permits and conservation fees apply, and we handle all of them within your safari package.

A few practical points for planning a visit:

• Access is by boat only — there is no road into the park.
• Chimpanzee trekking is limited to small groups and set time periods.
• Trails are steep and can be slippery; a reasonable level of fitness helps.
• Facilities are basic, so bring what you need and travel self-sufficiently.
• The dry season from June to October offers the best trekking conditions.

Gombe is a low-risk destination for most travellers, but its remoteness means preparation counts. The main health consideration is malaria, so consult a travel doctor about antimalarials before your trip and bring insect repellent for the evenings.

Because chimpanzees are susceptible to human diseases, responsible behaviour is part of the experience. Keep the required distance, follow your guide’s instructions, and do not trek if you are showing signs of illness.

• Take antimalarials and carry personal medication and a first-aid kit.
• Wear sturdy shoes for steep, sometimes muddy forest trails.
• Never trek when you have a cough, cold or fever.
• Keep a respectful distance from the chimps and avoid sudden noise.
• Leave no litter and follow all park rules.
