The Bwindi Impenetrable National Park (BINP) is in south-western Uganda. The park is part of the Bwindi Impenetrable Forest and is situated along the Democratic Republic of the Congo (DRC) border next to the Virunga National Park and on the edge of the Albertine Rift. Composed of 331 square kilometers (128 sq mi) of both montane and lowland forest, it is accessible only on foot. BINP is a United Nations Educational, Scientific and Cultural Organization-designated World Heritage Site.
Species diversity is a feature of the park. It provides habitat for 120 species of mammals, 348 species of birds, 220 species of butterflies, 27 species of frogs, chameleons, geckos, and many endangered species. Floristically, the park is among the most diverse forests in East Africa, with more than 1,000 flowering plant species, including 163 species of trees and 104 species of ferns. In particular, the area shares in the high levels of endemisms of the Albertine Rift.
The park is a sanctuary for colobus monkeys, chimpanzees, and many birds such as hornbills and turacos. It is most notable for the 340 Bwindi gorillas, half of the world's population of the critically endangered mountain gorillas.
