Lying between the Kogon River to the north and the Pongo River to the south, the Nunez empties into the Atlantic Ocean at the port town of Kamsar, along the coast of Guinea-Conakry. The river is swollen each year during the rainy season, producing floodplains and inland swamps. These floodplains are inhabited by the Nalu and Baga people. About 40 miles inland is the city of Boké; the largest on the river and the chief commercial center of Guinea. Here the river is 100m wide and 1m deep.
