Nyong River

Nyong River, stream in southwestern Cameroon, west central Africa. It rises 25 mi (40 km) east of Abong Mbang, in the northern rain forest. Its 400-mi (640-km) course, which roughly parallels that of the lower Sanaga River, follows a westerly direction, emptying into the Gulf of Guinea of the Atlantic Ocean at Petit Batanga, 40 mi south-southwest of Edéa. Rapids break the flow of the river at Mbalmayo and Déhané. Navigation is possible for about 155 mi for small steamboats from April to November between Abong Mbang and Mbalmayo.
