3. Brazzaville lies directly across the Congo River from Kinshasa, the capital of the Democratic Republic of the Congo. They are the closest pair of national capitals in the world.

7. Diosso Gorge, near the Atlantic coast, is sometimes nicknamed the “Grand Canyon of the Congo” because of its dramatic red and orange cliffs.

8. Odzala-Kokoua National Park is an expansive 13,500 square kilometer (5,200 square mile) protected area consisting of about 85% forest. It was established in 1935, making it one of the oldest national parks in Africa.

Geography of the Republic of Congo

The Republic of the Congo is one of the African countries and lies in Central Africa, with a short coastline on the Atlantic Ocean.

Its landscape is dominated by tropical rainforests and traversed by major river systems, with limited mountainous terrain.

Atlantic Coast & Coastal Plains

A narrow coastal plain stretches along the Atlantic Ocean in southwestern Congo. Pointe-Noire, the country’s principal port city, lies on the coast, while lagoons, mangroves and sandy beaches occur along parts of the shoreline.

Kouilou-Niari River

Mayombe Highlands & Niari Valley

Just inland from the coast, the forested Mayombe hills rise above the coastal plain. Farther east lies the lower Niari Valley, which contains a mixture of savanna, woodland and farmland.

Odzala-Kokoua National Park

Congo Basin

The Republic of Congo forms part of the vast Congo Basin, with around two-thirds of the country covered by forest. Extensive tropical rainforest covers much of the north, with low-lying wetlands and swamp forests occurring particularly in the northeast.

Pool Malebo

Congo River & Major Waterways

The Congo River forms much of the country’s eastern border with the Democratic Republic of the Congo. Brazzaville lies beside Pool Malebo, a broad lake-like section of the river opposite Kinshasa. Major northern rivers include the Sangha and Likouala, while the Ubangi forms part of the eastern border before joining the Congo River.


Republic of Congo flag

The Republic of the Congo introduced its green, yellow and red flag in 1959, shortly before gaining independence from France in 1960.

It was replaced in 1970 when the country became a Marxist one-party state, but the original flag was restored in 1991 during the return to multiparty democracy.
