It has safeguarded Ramsar sites in the Central African Republic, Cameroon, and Congo.

The Sangha River flows 140 miles (225 kilometers) south from Cameroon's border with the Central African Republic and Congo to Ouesso in Congo (Brazzaville). The river then flows 225 miles (362 kilometers) south-southeast and southwest to its mouth on the Congo River, south of Bobaka. Below Ouesso and periodically up to Nola, the Sangha River is navigable by riverboat all year. Its lower, swampy course breaks into multiple mouths and is linked to the Likouala aux Herbes, Likouala, and Ubangi (Oubangui) rivers via divergent tributaries.

At Nola in the western Central African Republic, the Sangha River is produced by the confluence of the Mambéré and Kadé rivers.
