Bwindi is also home to chimpanzees, black-and-white colobus monkeys, red-tailed monkeys, and grey-cheeked mangabeys — all of which can be encountered on forest walks without requiring a special permit. The primates are generally less shy than in unprotected forest, and spotting a troop of colobus in the canopy or hearing chimpanzees calling in the distance adds another layer to the forest experience.
Chimpanzee tracking is not formalised at Bwindi in the same way as gorilla tracking, but guides can take visitors to areas where they are regularly seen. For dedicated chimp tracking, Kibale Forest National Park — about 250 kilometres north — is a better dedicated option. But seeing multiple species of primates in the context of a gorilla trip adds real richness to any visit.
