Uganda and Rwanda are the only countries with endangered mountain gorillas. Uganda has more than half of the world’s mountain gorilla population living in the Virunga Mountain slopes in Mgahinga Gorilla National Park and Bwindi Impenetrable National Park. On the other side of the Virunga Mountain ranges, Rwanda’s Volcanoes National Park hosts 12 gorilla groups or troops each led by a Silverback which is the dominant male. Gorilla Tracking in both countries is safe and well-managed.
