The Niger River enters Nigeria from
the northwest, crossing the western part of the country to join the Atlantic
Ocean in the south. Near the coast, the river forms this delta with mangrove
forests, lagoons, and swamps stretching about 100 km (about 60 mi) inland. The
Niger Delta is the largest in Africa, covering an area of about 36,000 sq km
(about 14,000 sq mi).
