Gombe Stream National Park is situated beside Lake Tanganyika in Western Tanzania. It is about 16 kilometer north of Kigoma and is the smallest park in Tanzania, with an area of only 52 square kilometers.
The Park is within the Rift Valley. It is formed by a strip of land 16 kilometers long, lying between the eastern shore of the lake and the peaks of mountain range that form the Rift Escarpment.

Gombe Stream National Park is one of the few areas in Africa that offers havean to the chimpanzees. Apart from the Mahale Mountains south of Kigoma, there is nowhere else in the country where chimpanzees can be observed in the wild. Other primates found in the park are baboons, red colobus monkey and blue monkeys. Bushbucks, buffaloes, and leopards are also other mammals present in the park, and there is famous waterfall called Kakombe
Kigoma is a historical town, while visiting Gombe; one might spare some time to visit other places of interest such as Ujiji, the place where David Livingstone and Henry M Stanley met in 1871.
