Geography of the Republic of the Congo
Coordinates: The Republic of the Congo is located in the western part of Central Africa. Situated on the Equator, it is bordered by the Angola exclave of Cabinda to the south (201 km), the Democratic Republic of the Congo to the south and east (2,410 km), the Central African Republic (467 km) and Cameroon (523 km) to the north and Gabon to the west (1,903 km). Congo has a 169 km long Atlantic coast with several important ports. The Republic of the Congo covers an area of 342,000 km², of which 341,500 km² is land while 500 km² is water. Congo claims 200 nautical miles (370 km) of territorial sea.
The capital of the Republic of the Congo is Brazzaville, located on the Congo river immediately across from Kinshasa, capital of the Democratic Republic of the Congo. With a metropolitan population of approximately 1.5 million, Brazzaville is by far the largest city in the Republic, having almost twice the population of Pointe-Noire (663,400 as of the 2005 census), the country's second largest city. About 70% of the population lives in Brazzaville, Pointe-Noire, or along the railroad between them. See Also Geology in ROC

The terrain is a variation of coastal plains, mountaineous regions, plateaus and fertile valleys. About 70 percent of the country's area is covered by rain forest. The highest point, at 1,020 m, is Mont Nabeba in the Mayumbe mountains. The major rivers are the Congo River at the border with the Democratic Republic of the Congo, and the Kouilou-Niari River.
