Mahale Mountains National Park covers about 1,650 sq km on the remote eastern shore of Lake Tanganyika in western Tanzania, reachable only by boat or light aircraft. Established in 1985, the park protects the largest population of eastern chimpanzees in Tanzania alongside a dramatic backdrop of forested mountains rising directly from the lake, making it one of the most distinctive and least-visited wildlife destinations in East Africa.
The park at a glance
- About 1,650 sq km on Lake Tanganyika’s eastern shore, established in 1985
- Home to Tanzania’s largest population of eastern chimpanzees, estimated at around 800 to 1,000 individuals
- No roads reach the park; access is entirely by boat or chartered light aircraft
- Mountains rise directly from the lakeshore to over 2,400 metres, creating a rare combination of forest, mountain and lake scenery
Chimpanzee trekking
Mahale’s chimpanzees have been the subject of long-running research since the 1960s, and one habituated community allows visitors to track them on foot through steep, forested terrain with experienced guides. Sightings are not guaranteed given the dense forest and mountainous ground, but successful encounters offer an intimate, close-range view of chimpanzee behaviour that few other African destinations can match.
A lake without roads
Because no roads connect Mahale to the rest of Tanzania, the park has remained largely untouched by mass tourism, with a small number of camps set directly on the beach along the lakeshore. Lake Tanganyika’s clear water also supports swimming, snorkelling and fishing for visitors combining chimpanzee trekking with time on the water, a pairing rarely available alongside primate tracking elsewhere in Africa.
Things to do
- Chimpanzee trekking with experienced guides through Mahale’s forested slopes
- Swimming and snorkelling in Lake Tanganyika directly from camp beaches
- Fishing outings on the lake
- Birdwatching across the park’s forest and shoreline habitats
Practical information
- Reached only by boat from Kigoma or by chartered light aircraft, since there are no roads into the park
- Best visited in the dry season from late May to October, when trails are easier walking and chimpanzee tracking conditions are best
- Limited camp capacity and remote access make advance booking through an experienced operator essential
Mahale Mountains offers one of Africa’s most remote and rewarding chimpanzee-trekking experiences, set against a lakeside backdrop found nowhere else on the continent. Offmap Safaris can combine it with Kigoma and Gombe Stream for a full western Tanzania circuit.
