South and west Tanzania
There are many National Parks and Game reserves which remain largely unvisited. The Ruaha NP and Selous Game reserve are easily accessible from Dar Es Salaam as are Mikumi and Udzungwa. Some of these allow walking safaris which offer a new dimension your experience.
The parks of Gombe Stream and Mahale offer the opportunity to see Chimpanzee in the wild and visit Lake Tanganyika.
