Mahale Mountains

The Tongwe and Holoholo peoples lived along this shore of Lake Tanganyika for generations and were resettled outside the boundary when the park was established in 1985. Their knowledge of the forest underpins much of the guiding here, and many of the trackers working with the chimpanzee groups come from those communities.

Fishing villages line the lake to the north and south of the park, and dugout canoes still work the shallows at dawn using techniques largely unchanged for centuries. Lake Tanganyika supports one of the most productive inland fisheries in Africa.

Kigoma, the regional centre and the usual staging point for reaching Mahale, carries the better-known history of this coast. Nearby Ujiji was a major terminus on the nineteenth-century caravan routes from the Indian Ocean, dealing in ivory and enslaved people, and is where Stanley is said to have greeted Livingstone in 1871.

The Japanese research presence at Mahale, running since the 1960s, is itself part of the park's story and one of the longest continuous primate studies anywhere in the world.

Mahale exists for one animal. Roughly a thousand chimpanzees live in these forests, and the M-group has been studied by Japanese researchers since the 1960s, making them habituated enough to approach on foot.

Tracking is done on steep forest trails and is genuinely strenuous, but encounters are close and often prolonged. Red colobus, red-tailed and blue monkey, and yellow baboon share the forest. Elephant, buffalo and leopard occur in the higher and more remote reaches but are very seldom seen. There are no roads anywhere in the park.

Around 350 species have been recorded across forest, miombo and lakeshore, including several with a limited range in western Tanzania.

Crested guineafowl, Ross's turaco, palm-nut vulture and fish eagle are all regular, and the lakeshore adds waders and kingfishers. Birding is a pleasant secondary activity rather than the reason to come.

By Air

Most visitors fly. Scheduled and charter light aircraft reach the Mahale airstrip from Arusha and Dar es Salaam, usually via Kigoma or Katavi, followed by a boat transfer of one to two hours along the lakeshore to the camps.

By Boat

From Kigoma, a chartered boat takes four to six hours, and the MV Liemba lake ferry serves the area on an irregular schedule. There is no road access to the park at all, and no roads inside it.

Rain falls heavily from November through April, peaking around March, and the western slopes of the range catch a great deal of it. Annual rainfall is high, which is why the forest is so dense and the chimpanzees have such abundant fruiting trees.

The dry season from May to October is warm, clear and settled. Forest trails firm up considerably, the lake is at its calmest and clearest for snorkelling, and the chimpanzees tend to range lower down the mountain.

Humidity is the practical consideration rather than heat. Carry at least two litres of water on any trek and expect to be thoroughly wet through by the end.

Light long sleeves help against vegetation and insects on the forest trails.

May to October is the dry season and the established window for tracking. Trails are firmer and far easier going, and the chimpanzees tend to range lower down the mountain, which can turn a four-hour climb into a one-hour walk.

July to September is the peak within that window, with settled weather, clear lake conditions and the most reliable tracking. It is also the busiest period, though busy at Mahale still means a handful of guests.

November to April brings heavy rain. Trails become slippery and demanding, the chimpanzees often move higher in search of fruiting trees, and several camps close entirely.

The lake is at its clearest for snorkelling through the dry months, a genuine bonus of the same season.

If you are travelling this far, the mid-year window makes the effort and expense far more likely to pay off, since a shorter trek leaves time for the lake as well as the forest in a single day.

Chimpanzee tracking carries strict rules that exist to protect both you and the animals. Keep the required distance, wear a mask when instructed, and do not visit if you have any infectious illness, since chimpanzees are highly susceptible to human respiratory disease.

The terrain is steep and humid and tracking can last several hours, so a reasonable level of fitness is needed. Mahale is one of the most remote parks in Tanzania, with no road access and no medical facilities nearby. Insurance covering air evacuation is essential.

Malaria prophylaxis is essential in this low-altitude, humid environment. Use repellent and nets consistently.

A yellow fever certificate is commonly required, and typhoid, hepatitis A and B and tetanus vaccinations are recommended. Anyone with a cold, flu or stomach illness should not track chimpanzees on that day, without exception. Lake Tanganyika is considered bilharzia-free near the camps, but confirm locally before swimming.
