Nyungwe is one of Africa's great forests — an ancient montane rainforest covering roughly 1,000 square kilometres that survived the ice ages intact. More than 13 primate species live here, including chimpanzees and L'Hoest's monkeys, and over 275 bird species have been recorded. The road from Cyangugu passes through the park and is spectacular in itself.
The headline activity is chimpanzee tracking: permits must be booked in advance and success is not guaranteed, but following a habituated chimp group through the dense canopy is unforgettable. The Igishigishigi Trail leads to a suspension bridge hanging 50 metres above the forest floor — one of only a handful of canopy walkways in Africa. The Uwinka Reception Centre, about 50 km east of Cyangugu along the main road, is the starting point for most trails.
Colobus monkeys are extremely common and often seen in large troops along the roadside. Dawn is the best time for both primates and birds.
