Congo-Nile Divide

The Congo-Nile Divide is a prominent mountain range that runs north-to-south through Rwanda, serving as the hydrographic boundary between Africa's two largest river basins. To the west, water flows into the Congo River system and eventually into the Atlantic Ocean, while to the east, it drains into the Nile Basin, reaching the Mediterranean Sea. This topographic barrier consists of rugged highlands that reach elevations of up to 3,000 meters. It plays a critical role in Rwanda's climate by intercepting moist air from the Congo Basin, resulting in higher rainfall in the western regions. Major ecological zones, including the Nyungwe National Park, are situated along this divide. Geologically, it is part of the Albertine Rift and was formed by tectonic uplifting during the creation of the East African Rift System. The famous 'Congo Nile Trail' gives hikers a unique opportunity to experience the divide's dramatic scenery, including panoramic views of Lake Kivu and the rolling landscapes of central Rwanda.
