If your appetite for game viewing hasn't been satiated in the Northern Circuit parks, then the lesser-visited parks in the Southern and Western circuits can be accessed by flights from Dar es Salaam. The lodges and camps in these are far more remote and intimate, so this is the ideal destination for those looking for a wilderness experience away from hordes of safari-goers.

Days 15-23: Safari in the South
The Selous Game Reserve and the Ruaha and Kitavi national parks in Tanzania's south are some of the wildest areas of East Africa and are fairly inaccessible except by small plane. They operate on a high-cost, low-impact system, and those who can afford it will enjoy the tremendous solitude of the bush. The three parks are connected by flights, so spend at least 2 to 3 nights in each; they can be visited in any order. The landscapes are reminiscent of what the whole of East Africa looked like when it belonged only to the wildlife. About the same size of Denmark, the vast Selous is the largest game reserve in Africa, and it's reputedly home to more than a million animals. Both Ruaha and Katavi offer untouched swathes of game-filled wilderness and receive only a handful of visitors each year. While the parks' few tented camps are isolated enough as it is, there's the additional option of going fly-camping, guided walking safaris where visitors sleep out in the open with only a mosquito net between them and the African sky. The final flight will return you to Dar es Salaam.
Days 23-28: Western Circuit
For those with more time, flights (or a long and arduous train ride) connect Dar es Salaam to Kigoma on the shores of Lake Tanganyika in Western Tanzania. The main reason to come to this isolated spot is to see chimpanzees in the Gombe Stream National Park and the Mahale Mountains National Park. Both are on the lakeshore and feature very basic rest camps, as well as luxury lodges. Visitors can go on guided forest walks to see the chimpanzees. The final flight will return you to Dar es Salaam.
