Mahale Mountains National Park

Deep in the Kigoma region, Mahale Mountains National Park offers a unique and unforgettable wildlife experience. Home to approximately 700-1000 chimpanzees, representing the world’s largest protected population of the eastern subspecies, it is one of the best places to observe these fascinating primates in their natural habitat. The Mimikire clan, known as the M-group, is of particular interest, having been monitored by researchers since 1965. This group of about 60 chimpanzees roams freely throughout the park and is surprisingly relaxed around humans, allowing close observation. To ensure the chimps’ health and safety, visitors must wear face masks and maintain a respectful distance, with a one-hour limit for close observation.  

Mahale National Park began as a Japanese wildlife research center and was officially designated a national park on June 14, 1985, under Government Notice No. 262. The park encompasses a diverse landscape, including a mountainous inland area and the eastern shore of Lake Tanganyika, covering 1,613 square kilometers. The highest peak, Nkungwe, rises to 2,470 meters above sea level.

Beyond chimpanzees, the park reveals a rich biodiversity. Mahale is exceptional for its wide variety of habitats, including rainforest, woodland, bamboo forest, montane forest, and mountain grasslands. This mosaic supports a unique mix of flora and fauna. The park is home to eight (possibly nine) primate species in addition to chimpanzees: yellow baboons, blue monkeys, red colobus, pied colobus, and vervet monkeys, as well as two or three species of galago. The park also boasts at least 337 bird species, many of which are rare and endemic to the Albertine Rift, such as Pel’s fishing owl.  

The park’s diverse ecosystem extends into Lake Tanganyika, which forms part of Mahale’s eastern border. This lake, the world’s second-longest and second-deepest freshwater lake (673 km long and 60-80 km wide), is renowned for its exceptional freshwater fish diversity. It harbors at least 400 fish species, about 250 of which are cichlids, with 98% being endemic.  

TANAPA regulations require that visitors be at least 12 years old to participate in chimpanzee trekking.
