Course
editThe Nyong originates 40 km (25 mi) east of the town of Abong-Mbang, where the northern rain forest feeds it.[2] The river's length is almost parallel to the lower reaches of the Sanaga River. Its mouth is in Petit Batanga, 60 km (40 mi) south-southwest of Edéa.[3] In two places, Mbalmayo and Déhané, the river has huge rapids. The first 400 km (250 mi) of the river, between Abong-Mbang and Mbalmayo, are navigable for small boats from April to November.
