Mahale Mountains National Park lies on the shores of Lake Tanganyika in Kigoma Region, Tanzania. Named after the Mahale Mountains range that is within its borders, the park has several unusual characteristics. First, it is one of only two protected areas for chimpanzees in the country. (The other is nearby Gombe Stream National Park made famous by the researcher Jane Goodall.) The chimpanzee population in Mahale Mountains National Park is the largest known and due to its size and remoteness, the chimpanzees flourish. It also the only place where chimpanzees and lions co-exist. Another unusual feature of the park is that it is one of the very few in Africa that must be experienced by foot. There are no roads or other infrastructure within the park boundaries, and the only way in and out of the park is via boat on the lake. The Mahale mountains were traditionally inhabited by the Batongwe and Holoholo people, with populations in 1987 of 22,000 and 12,500 respectively. When the Mahale Mountains Wildlife Research Center was established in 1979 these people were expelled from the mountains to make way for the park, which opened in 1985. The people had been highly attuned to the natural environment, living with virtually no impact on the ecology
Katavi National Park is a Tanzanian national park created in 1974 and is located in Katavi Region, Tanzania. It is a very remote park that is less frequently visited than other Tanzanian national parks. The park is approximately 4,471 square kilometers (1,726 sq mi) in area, which makes it the third largest national park in Tanzania. The park encompasses the Katuma River and the seasonal Lake Katavi and Lake Chada floodplains. Wildlife features include large animal herds, particularly of Cape Buffaloes, zebras, wildebeest, giraffes, and elephants, plus along the Katuma river, crocodiles and hippopotami which upon annual dry seasons results in mudholes that can be packed with hundreds of hippos. Carnivorous animals that roam this park are cheetahs, wild dogs, hyenas, leopards, and lions. Some sources claim a very high biodiversity in the park, although there are also reports of wildlife decline due to illegal hunting and poaching, presumably 'bushmeat' sustenance. Katavi has fewer human visitors and jeeps conducting game drives than other Tanzania parks.
Gombe Stream National Park is located in western Kigoma Region, Tanzania, 10 miles (20 km) north of Kigoma, the capital of Kigoma Region. Established in 1968, Gombe is one of the smallest national parks in Tanzania, with only 13.5 square miles (35 sqkms) of protected land along the hills of the eastern shore of Lake Tanganyika. The terrain is distinguished by steep valleys, and the forest vegetation ranges from grassland to woodland to tropical rainforest. Accessible only by boat, the park is most famous as the location where Jane Goodall pioneered her behavioral research conducted on the chimpanzee populations. The Kasekela chimpanzee community, featured in several books and documentaries, lives in Gombe National Park. Gombe’s high levels of diversity make it an increasingly popular tourist destination. Besides chimpanzees, primates inhabiting Gombe include beachcomber olive baboons, red colobus, red-tailed monkeys, blue monkeys, and vervet monkeys. Red-tailed monkeys and blue monkeys have also been known to hybridize in the area. The park is also home to over 200 bird species and bushpigs. There are also many species of snakes, and occasional hippopotami and leopards. Visitors to the park can trek into the forest to view the chimpanzees, as well as swim and snorkel in Lake Tanganyika with almost 100 kinds of colorful cichlid fish.
