Mahale Mountains National Park
“You track chimpanzees through mountain forest in the morning and swim in Lake Tanganyika in the afternoon. Nowhere else offers that.”
A remote mountain forest on Lake Tanganyika holding around a thousand chimpanzees, reached only by boat and paired with some of the clearest freshwater in the world.
About Mahale Mountains.
Mahale is one of East Africa's most distinctive chimpanzee destinations and remains very lightly visited. Around 1,600 square kilometres of mountain forest rise steeply from the eastern shore of Lake Tanganyika to peaks above 2,400 metres, and roughly a thousand chimpanzees live in it. The habituated Mimikire — or M — group has been studied by Japanese researchers since 1965, and tracking them is remarkably intimate: encounters often take place on the forest floor with a group of forty or more animals moving around you.
What makes Mahale unique is the combination. In the morning you climb through forest with a guide; in the afternoon you swim, kayak or snorkel in water clear enough to see the bottom at fifteen metres, from a white sand beach with forest coming down to meet it. Lake Tanganyika is the second-deepest lake in the world and holds hundreds of endemic cichlids.
Access is the price of admission: a charter flight to the airstrip near Kalema, then an hour or so by boat, with no road at all. Lodges are few and small, and the season runs roughly May to October when trails are driest, though many operators run into December. Because there are no roads inside the park, everything happens on foot or on the water.
