Mgahinga Gorilla National Park - gorilla trekking, mountain climbing, forest walks.
 

Mgahinga Gorilla National Park is Uganda's smallest national park. It protects the Ugandan part of the Virunga Mountains, a range comprising six extinct and three active volcanoes and straddling the borders of Uganda, Rwanda and the Congo. Although Mgahinga is best known for gorilla tracking the park offers a far broader range of activities than any other of the mountain reserves - caving, forest walks, and day hikes to the three volcanic peaks that lie partly within Uganda. Anybody who enjoys challenging day hikes or who has an interest in natural history could happily spend a week based at Mgahinga without ever going gorilla tracking.
Three extinct peaks lie partially within Mgahinga. The southern skyline dominated by the steep volcanic cones of the Virungas is one of the most memorable sights in East Africa. All three mountains can be climbed without specialised mountaineering equipment, although some warm clothes and good walking shoes are a good idea. Mt Muhavura (4,127m) takes about 8 hours to climb and descend again.
 
Mt Sabyinyo (3,645m) also takes about 8 hours and Mt Gahinga (3,475m) takes about a 6 hours climb and descend. The higher reaches of these peaks are covered in afro-alpine vegetation, while the lower slopes are covered in afro-montane forest and they harbour a wide variety of wildlife.
The park protects 76 mammal species, including the golden monkey (a localised and distinctive race of the blue monkey), black-and-white colobus, mountain gorilla, leopard, elephant, giant forest hog, bushpig, buffalo, bushbuck, black-fronted duiker and several varieties of rodents, bats and small predators. Bafflingly, only 87 bird species have been recorded in Mgahinga, possibly a reflection of the park's small size (it only covers an area of 33km2) but also suggesting that no serious study of its avifauna has ever been undertaken. However, the park is still of great interest to bird-watchers, as several of the species recorded are localised forest birds, and 12 are considered to be endemic to the Albert Rift region.
