Sightings aren’t as reliable or as clear as gorillas however, since they often remain in dense forest, but their engaging playfulness and human-like characteristics make the long day worthwhile.

While chimps tend to attract most of the spotlight in Nyungwe, sightings of habituated troops of other monkeys – Angolan colobus (troops of which number up to 400), Dent’s monkey (a local race of blue monkey) and grey-cheeked mangabeys (the last two often seen together) – are virtually guaranteed on guided walks. Other monkey possibilities include l’Hoest’s and diademed monkeys, Olive baboons, vervet monkeys, while owl-faced monkeys and possibly golden monkeys.
