Kahuzi-Biega National Park

Kahuzi–Biega National Park is one of Africa’s most remarkable primate sanctuaries and the most important stronghold of the endangered Eastern Lowland Gorillas, also known as Grauer’s Gorillas. Located in the eastern region of the Democratic Republic of Congo near the city of Bukavu, this UNESCO World Heritage Site covers approximately 6,000 square kilometers, making it one of the largest protected rainforests in the Albertine Rift. Its unique combination of lowland tropical forest and high-altitude volcanic mountains creates exceptional biodiversity and a pristine wilderness experience.

Named after Mount Kahuzi (3,308 m) and Mount Biega (2,790 m), the park’s twin dormant volcanoes dominate its landscape, offering sweeping views of ancient rainforests, valleys, and rugged peaks. Kahuzi–Biega is known for its tranquility, untouched nature, and intimate gorilla encounters that are often considered among the most rewarding in Africa.

Eastern Lowland Gorillas in Kahuzi–Biega National Park

Kahuzi–Biega is home to the world’s largest remaining population of Eastern Lowland Gorillas (Gorilla beringei graueri) — the biggest of all gorilla subspecies. Unlike mountain gorillas, these gorillas live in both lowland and montane forests and can form larger families.

Several habituated gorilla groups are open for trekking, including well-known families such as Chimanuka and Mpungwe. Trekking experiences begin from the Tshivanga Visitor Center with a morning briefing, followed by guided hikes through dense forests. Gorilla trekking in Kahuzi–Biega typically involves less steep climbing than mountain gorilla treks, making it accessible to a wider range of visitors.

Eastern Lowland Gorillas live in cohesive social groups led by a dominant silverback, who oversees the group’s movement, feeding routines, and protection. They feed on fruits, leaves, shoots, bark, and herbaceous plants, and often build new nests each night on the ground or in trees.
