Mayumba National Park protects an area of coastal sea of approximately 900 square kilometers, and a narrow 1 x 60 km strip of beach and coastal vegetation. The Mayumba coastline is characterized by long exposed sandy beaches and extensive freshwater, tidal or brackish lagoons. The beaches support a rich shoreline fauna including monitor lizards, genet, mongoose, ghost crabs and shore birds. Buffalo, elephant and other forest animals are frequently found on the beaches and amid the dense dune vegetation that fringes the coast. Mandrill, gorilla, chimpanzee, and other primates inhabit the forest-savannah mosaic behind the dunes.
