GORILLAS IN BWINDI
The mountain gorilla is the world's most endangered ape and only found in small portions of protected forests in southwestern Uganda, northwestern Rwanda and eastern Democratic Republic of Congo (DRC).
The forests are also home to many wonderful birds, primates, large mammals, reptiles, insects and plants. The mountain gorillas are divided into two populations.
2003 figures estimate the total population to be about 706 individuals. One population of about 320 is found in Bwindi Impenetrable National Park in southwestern Uganda, covering 330 km², and the other 386 in the Virunga Volcano Range (covering 3 National Parks in 3 countries: Mgahinga Gorilla National Park in Uganda, Volcanoes National Park in Rwanda and Virunga National Park in the Congo (DRC).
Gorilla tracking (gorilla trekking) is an intense experience that can take up to 6 hours. The guide leads you through the gorilla's world, explaining aspects of their ecology and behavior along the way. It's possible to hire a porter (a person who will carry your bag) for about 5 to 10 dollar.
Note that the gorillas are wild creatures with no fixed routine so success is not guaranteed, but your chances are very good, > 95%. The guides and trackers have helped to habituate the gorilla groups and know them intimately.
