Bwindi Impenetrable National Park

Bwindi Impenetrable National Park is a 331 km² protected rainforest in southwestern Uganda, at the edge of the Albertine Rift. It is one of the most biologically diverse areas on Earth and is best known for hosting approximately half of the world's remaining mountain gorillas (about 459 individuals as of the latest census). The park also shelters 120 mammal species, 348 bird species (including 23 Albertine Rift endemics), and over 220 butterfly species. Gorilla trekking permits allow small groups of tourists to visit habituated gorilla families. Bwindi was inscribed as a UNESCO World Heritage Site in 1994. The park's name derives from its dense, nearly impenetrable vegetation, which includes bamboo, montane, and lowland forest.
