Bwindi Impenetrable National Park lies in southwestern Uganda on the edge of the Rift Valley. Its mist-covered hillsides are blanketed by one of Uganda's oldest and most biologically diverse rainforests, which dates back over 25,000 years and contains almost 400 species of plants. More famously, this “impenetrable forest” also protects an estimated 320 mountain gorillas - roughly half of the world’s population, including several habituated groups, which can be tracked.
This biologically diverse region also provides shelter to a further 120 mammals, including several primate species such as baboons and chimpanzees, as well as elephants and antelopes. There are around 350 species of birds hosted in this forest, including 23 Albertine Rift endemics.
This forest is a UNESCO World Heritage site. It is deep within it that you can come face to face with its most famous resident - the mountain gorilla, an endangered primate.
