The highlands comprise a group of plateaus and volcanic mountains, including the Mbeya Mountains, Poroto Mountains, Kipengere Range, Mount Rungwe, Kitulo Plateau, Umalila Mountains, and Matengo Highlands. The Ufipa Plateau extends northwest, between Lake Tanganyika and Lake Rukwa. The eastern and western branches of the East African Rift converge in the highlands, and the Western Rift continues south as the valley of Lake Malawi. To the northeast, the Makambako Gap separates the Southern Highlands from the Eastern Arc Mountains.
