The Democratic Republic of the Congo (DRC) is the largest country of sub-Saharan Africa, occupying some 2,344,858 square kilometres (905,355 sq mi). Most of the country lies within the vast hollow of the Congo River basin. The vast, low-lying central area is a plateau-shaped basin sloping toward the west, covered by tropical rainforest and criss-crossed by rivers. The forest center is surrounded by mountainous terraces in the west, plateaus merging into savannas in the south and southwest. Dense grasslands extend beyond the Congo River in the north. High mountains of the Ruwenzori Range are found on the eastern borders with Rwanda and Uganda.
The Congo River, formerly also known as the Zaire River, is the second-longest river in Africa, shorter only than the Nile, as well as the third largest river in the world by discharge volume, following the Amazon and the Ganges rivers. It is also the world's deepest recorded river, with measured depths of around 219.5 m (720 ft). The Congo-Lualaba-Chambeshi River system has an overall length of 4,700 km (2,920 mi), which makes it the world's ninth-longest river. The Chambeshi is a tributary of the Lualaba River, and Lualaba is the name of the Congo River upstream of Boyoma Falls, extending for 1,800 km (1,120 mi).
The Lualaba River flows entirely within the eastern part of Democratic Republic of the Congo. It provides the greatest streamflow to the Congo River, while the source of the Congo is recognized as the Chambeshi. The Lualaba is 1,800 kilometres (1,100 mi) long. Its headwaters are in the country's far southeastern corner near Musofi and Lubumbashi in Katanga Province, next to the Zambian Copperbelt.
Salonga National Park is a national park in the Democratic Republic of the Congo located in the Congo River basin. It is Africa's largest tropical rainforest reserve covering about 36,000 km2 or 3,600,000 hectares. It extends into the provinces of Mai Ndombe, Equateur, Kasaï and Sankuru. In 1984, the national park was inscribed on the UNESCO World Heritage List for its protection of a large swath of relatively intact rainforest and its important habitat for many rare species. In 1999, the site has been listed as endangered due to poaching and housing construction. Following the improvement in its state of conservation, the site was removed from the endangered list in 2021.
