Gombe Stream National Park is located in the western Kigoma Region, Tanzania, 20 km north of Kigoma. Established in 1968, Gombe is the smallest national park in Tanzania, with only 52 sq km of forest running along the hills of the eastern shore of Lake Tanganyika. It is located only 100km north of Mahale Mountains National Park and is accessible only by boat. The terrain is distinguished by steep valleys, and the forest vegetation ranges from grassland to alpine bamboo to tropical rainforest. Gombe Stream is best known as the place where Jane Goodall did her pioneering studies on chimpanzees, beginning in the 1960s and continuing until this day. It’s one of the two places in Tanzania for a chimpanzee safari. In the Gombe Stream National Park the chimps don’t roam as far in the wet summer season so may be easier to find on walks and hikes through the forest. It might be better to visit between February and June, or during November and December when there is a higher likelihood of being able to observe the chimps while they are less active. There are no guarantees, but most guests allow 2 days for a chimpanzee safari.
