Nyungwe Forest is a massive montane forest, in southern Rwanda, the largest in Central Africa, and has thirteen species of primate including chimpanzee, Rwenzori colobus and l'Hoest's monkey. The colobus live in large groups, including a four hundred-strong semi-habituated group thought to be the largest troop of arboreal primates in Africa.

Nyubgwe forest's primates include the chimpanzee, which are slowly being habituated. The terrain and undergrowth make chimpanzee tracking difficult but there is a fifty per cent chance of seeing chimpanzees here.

Nyungwe Forest is one of Rwanda's hotspots for birding. There are over 300 species, including the Handsome Francolin, the remarkable, 'painted' Rwenzori Turaco, Mountain Black Boubou, Rwenzori Batis, Yellow-eyed Black Flycatcher, Archer's Robin-chat, Rwenzori Hill Babbler, Red-faced Woodland Warbler, the rare Grauer's Rush Warbler, Neumann's Warbler, Mountain Masked Apalis, the near-endemic Kungwe Apalis and a cluster of colourful Sunbirds including Ruwenzori Double-collared, Purple-throated, Blue-headed and the stunning Regal Sunbird. It is the only site where the sought-after Red-collared Mountain Babbler can be sought in safety.
