Visiting one of the waterfalls: The most popular waterfall is the Isumo waterfall located close to the luxury Nyungwe House. To reach this waterfall, you will go through the Isumo Waterfall Trail. This trail is not very long but involves passing through slippery and steep areas of the park after which you descend to a very dense part of the forest before seeing the waterfall. The Isumo waterfall squeezes through a narrow section of rock before plunging down and continuing deep into the forest as a stream. The reward for such a difficult hike are the amazing sounds, cool breezes and views of the dense forest. As you retreat back to your hotel you will have many more opportunities to see insects, birds, frogs and some of the primates of the forest.
