Kigezi is also the home to the chain of volcanic mountains, the Virunga Mountains, located in what is now Kisoro District, and which also form the south-west Uganda border with the Democratic Republic of Congo and Rwanda.
Located in the Ugandan part of the Virunga Mountains is Mgahinga Gorilla National Park which, along with the nearby Bwindi Impenetrable National Park are home to the internationally famous mountain gorilla populations.
The mountains also form part of the watershed between the two major African rivers, the Nile and the Congo, with the highest peak on the Uganda side of the border being Mount Muhabura.
In the intervening valleys, often one finds expansive swampy areas, some of which, particularly those in Kabale District, have been reclaimed for pastureland.
