The terrain of Congo is dominated by a vast central plateau which gradually slopes towards the Atlantic Ocean. Dense rainforests cover much of the country, making it one of the most biodiverse regions in the world. The Congo River, one of the world's great rivers, cuts through the country from east to west. The river basin and its tributaries create a system of interconnected lakes and wetlands.
The elevation varies greatly in Congo — from the highest peaks reaching over 1000m to the lowest point at sea level. The relief of the country is a product of the region's geological history and the powerful forces that shaped its landscape over hundreds of millions of years.
Congo's mountains mostly lie in the eastern part of the country. They were formed by volcanic activity and tectonic forces. The Mitumba Mountains and the Ruwenzori range, both part of the East African Rift's western branch, ascend to an elevation of over 5,000 meters.
The country's coastal plains are mostly below sea level and are prone to flooding during the rainy season. Rivers flow gently through these plains, creating a unique ecosystem of swamps and wetlands that are home to many plant and animal species.
Mount Stanley is the highest point in Congo, reaching an elevation of 5,109 meters. It is part of the Ruwenzori mountain range and is shared with Uganda. Mount Stanley is a challenging climb, and only experienced mountaineers attempt to summit it.
The lowest point in Congo is at sea level, where the Congo River flows into the Atlantic Ocean. The river is one of the largest in the world and is a vital lifeline for the people of Congo.
Congo's topography is similar to other countries in the region such as Cameroon, Gabon, and the Central African Republic. All these countries have a varied terrain, with mountains, forests, rivers, and coastal plains. The region is home to some of the world's most biodiverse ecosystems.
