Virunga National Park (covering an area of 790,000 ha) comprises an outstanding diversity of habitats, ranging from swamps and steppes to the snowfields of Rwenzori at an altitude of over 5,000 m, and from lava plains to the savannahs on the slopes of volcanoes. Mountain gorillas are found in the park, some 20,000 hippopotamuses live in the rivers and birds from Siberia spend the winter there.

Virunga National Park is notable for its chain of active volcanoes and the greatest diversity of habitats of any park in Africa: from steppes, savannas and lava plains, swamps, lowland and Afromontane forests, to the unique Afroalpine vegetation and icefields of the Ruwenzori mountains, which culminate in peaks above 5000m.

The site includes the spectacular Ruwenzori and Virunga Massifs, including Africa's two most active volcanoes. The great diversity of habitats harbors an exceptional biodiversity, including endemic as well as rare and globally endangered species, such as the mountain gorilla.
