River Gambia National Park, established in 1978, is located in the Niamina East district of Central River Division, along the Gambia River's left bank. The park spans 585 hectares, including the Baboon Islands archipelago, home to a tropical riparian forest. Known for its chimpanzee-reintroduction project initiated in 1979, the park is a sanctuary for several groups of chimpanzees, as well as other species like Guinea baboons and red colobus. It also supports rare mammals such as hippopotamuses, aardvarks, and the West African manatee. Its riparian forest supports rich biodiversity, though human interaction is minimized to protect both animals and visitors.
