The southern circuit includes parks and reserves that can be visited using Dar es Salaam as a starting point. The Selous Game Reserve currently Nyerere National Park to the south of Mikumi is great for river experiences on the Rufiji River and also for walking safaris. Udzungwa Mountains National Park is all about forests, waterfalls and weird endemics, while Ruaha National Park just west of Iringa is the gem of the southern circuit.
