Bwindi Impenetrable National Park - gorilla trekking, chimpanzees & bird watching.
 
Bwindi Impenetrable National Park, located in southwestern Uganda on the edge of the western Rift Valley lies on the Zaire border adjacent to the Parc National des Virungas. It is one of the largest (331 sq. km) natural forests in East Africa and contains both montane and lowland forest. It supports a large number of plants and animals endemic to the region, but most notably half of the world's population of Mountain Gorillas. The more than 300 Mountain Gorillas, divided into a dozen groups, make up the world's largest surviving population.
 
 

The rugged terrain makes hiking in search of the gorillas streneous work. Tracking begins with a fairly strenous walk through the forest up steep and slippery slopes, to where the gorillas were found on the previous day. Then the trackers look for any signs - pressed-down grass, broken twigs, dung - that might tell them the direction the group has taken. Visitors follow through the dense undergrowth until they reach where the gorillas spent the night. Then the search continues, at times crawling through the thickets, until the gorillas are found. Mountain Gorillas can cover long distances each day and tours can last anywhere between three to eight hours.

 

Even if you don't go see the gorillas, there is plenty to do in the Impenetrable Forest. You can join guided walks and choose between a two-hour stroll to some beautiful waterfalls and various hikes, lasting up to seven-hour and leading to a number of peaks. The area around Buhoma is an excellent place for watching primates and birds and you may catch a glimpse of the noisy but evasive Chimpanzees or the beautiful Hornbills and Turacos. The forest is home to over 90 species of mammals, 300 species of birds, 200 species of butterflies, 160 species of trees and over 100 species of ferns, making it one of the richest ecosystems in Africa.
