Western Tanzania is dominated by three enormous lakes: Victoria, Nyasa, and Tanganyika – the world’s second-deepest lake in the world. Lake Victoria is the Nile’s principal source and offers several attractions among them Ukerewe and Rubondo Islands. The Gombe Stream and Mahale Mountains National Park are both located on the east bank of Lake Tanganyika and can only be reached by boat. This also applies to Rubondo National Park, a mysterious, uninhabited island in the middle of Lake Victoria. An archaic Katavi National Park is also located here.
Katavi National Park is located in the western part of Tanzania with approximately 4,471 square kilometers (1,726 sq mi) in the area which makes it the third-largest National Park in Tanzania. This pristine park is quite hard to access by road, so the easiest way in and out is by charter flights. Katuma River found in the park plays an important role during the dry season when animals gather along the river in search of water. Between June and October, Katavi National Park offers fascinating wildlife viewing.
