The park lies west of the Bakavu town in South Kivu Province, covering an area of 6,000 km (2,300 sq mi). A small part of the park is in Mitumba Mountain range of the Albertine Rift in the Great Rift Valley, and the larger part is in lowland terrain. A corridor of 7.4 km (4.6 mi) width joins the mountainous and lowland terrain. The eastern part of the park is the smaller mountainous region measuring 600 km (230 sq mi); the larger part measures 5,400 km (2,100 sq mi) and consists mainly of lowland stretching from Bukavu to Kisangani, drained by the Luka and Lugulu rivers which flow into the Lualaba River. Two dormant volcanoes are set within the park's limits and lend their names to it: Kahuzi (3,308 m (10,853 ft)) and Biéga (2,790 m (9,150 ft)).
