Nyungwe National Park lies in southwest Rwanda, partly abutting the Burundi border. It's a vast area of mountain rainforest, home to many species of chimpanzees, plus owl-faced and colobus monkeys. The Canopy Walkway, part of the Igishigishigi Trail, is a high suspension bridge with views over the valley and surrounding forests. A trail runs to the Kamiranzovu Marsh, with its birdlife, orchids and waterfall.
