A 331 km² primeval rainforest in southwest Uganda, famous as a refuge for roughly half of the world’s mountain gorillas (several gorilla groups are habituated for visits). This UNESCO World Heritage Site is exceptionally biodiverse – the “Impenetrable Forest” lives up to its name with dense jungles harboring over 1,000 flowering plant species, 120 mammal species (from elephants and duikers to chimpanzees), and 350+ bird species, offering one of Africa’s richest ecosystems in a compact area.
