Kigoma

Kigoma is a town and lake port in western Tanzania, on the eastern shore of Lake Tanganyika and close to the border with Burundi. It serves as the capital for the surrounding Kigoma Region. The historic trading town of Ujiji is 6 km south-east of Kigoma.
 
Kigoma is the perfect base for extraordinary safaris to both Gombe Stream National Park and Mahale Mountains National Park, famed for their wild chimpanzee populations and stunning settings - you can get more information on both parks at the Tanzania Parks official website. You could also consider a visit south to Katavi National Park, a giant park (in fact it is Tanzania's third largest) full of the big five animals, as well as healthy wild dog and cheetah populations, but with only a few hundred tourists visiting a year.
