Mahale National Park
Mahale Mountains is home to some of Africa’s last remaining wild chimpanzees: a population of roughly 800 (only 60 individuals forming what is known as "M group"), habituated to human visitors by a Japanese research project founded in the 1960s. Tracking the chimps of Mahale is a magical experience. The guide's eyes pick out last night's nests - shadowy clumps high in a gallery of trees crowding the sky. Scraps of half-eaten fruit and fresh dung become valuable clues, leading deeper into the forest. Butterflies flit in the dappled sunlight.
