Nyungwe National Park is the largest intact montane forest in the region. It is very dense and has amazingly thick vegetation that may make you feel as though you have stepped back into the Jurassic period. Nyungwe is home to chimpanzees and 13 other species of primates. The most popular to trek after the chimps are the Colobus monkey. Other activities include the waterfall hike, the canopy walk, visiting the tea factory and of course more birding. Nyungwe is the furthest park from Kigali, about an 7 hour drive but well worth it if you have two nights to be there.
