Kahuzi-Biega National Park

The park is defined by its dramatic altitudinal range, dropping from the twin volcanic plugs of Kahuzi and Biega at over 3,000 metres down through successive bands of forest: HageniaHypericum woodland at the summit, bamboo belt, then dense virgin rainforest that extends to the lowland Congo basin, creating one of the most ecologically compressed protected areas in Africa.

The most celebrated inhabitants are the eastern lowland gorillas, also called Grauer's gorillas, which are larger and darker than their mountain cousins and live in larger social groups; tracking them through the dense, wet undergrowth of the highland sector requires considerable physical effort and rewards with encounters of great intimacy.

Lush river valleys dissect the park's lower slopes, choked with papyrus and Phragmites reeds that provide corridors for forest elephants to move between the park and surrounding farmland, a movement that generates chronic conflict with local communities even as the elephants help seed new forest areas through their seed dispersal.

The montane forest above 2,200 metres is shrouded in mist for much of the year, the trees hung with lichen and moss that drip continuously and create an atmosphere of saturated green silence broken only by the calls of the Rockefeller's sunbird and the shuffle of a gorilla family moving through the canopy above.

Biodiversity surveys continue to add species previously unknown to science, including a new species of rodent discovered in the high-altitude zone in 2022, underscoring how much remains scientifically undocumented in this remote and logistically demanding landscape.

The nearby shores of Lake Kivu at Bukavu provide a contrasting backdrop, a deep tectonic lake of extraordinary clarity bordered by steep forested hillsides that plunge directly into its deep-blue waters, with very little littoral zone, making the lake visually dramatic but limiting the beach-based tourism that characterises East Africa's Great Lakes.

The Itombwe Mountains to the south of the park, though not part of the protected area, form a critical wildlife corridor connecting the highland forests of Kahuzi-Biega to montane habitats further south, and the wider landscape surrounding the park is increasingly recognised as essential for the long-term viability of Grauer's gorilla populations that move between protected and unprotected forest.

The biodiversity of the lowland sector is characterised by a completely different suite of species adapted to the warmer, wetter conditions below 1,200 metres, including forest buffalo, bongo antelope and the African forest elephant that migrates seasonally between the park and the surrounding community lands in search of salt licks and seasonal fruit crops.

It protects the last viable population of eastern lowland gorillas (Grauer's gorilla), a subspecies found almost exclusively within DRC and considered endangered by the IUCN.

The park spans an extraordinary altitudinal gradient from 600 to 3,308 metres, capturing multiple distinct ecosystems in a single protected area.

The area around Bukavu on Lake Kivu offers some of the most scenic lake-front terrain in Central Africa, with volcanic geology visible in every direction.
