The primates are among the most popular features of Uganda. The largest yet most peaceful are the gorillas, who share 95% of their genes with humans. The mountains of Bwindi and Mgahinga National Parks are home to five habituated and endangered gorilla troops. Limited numbers of tourists can visit the gorillas (only 30 passes are issued per day), so as to cut down on any disruption to the gorillas in their natural environment. The chimpanzees (who are genetically even closer to humans) have been habituated for tourists, and can be visited in one of four areas which  include; the Kibale and Budongo Forests, the Kyambura Gorge, and Ngamba Island. Several different species of golden monkeys can also be seen in the parks of Uganda, and visitors are likely to witness several over the course of a short hike through one of the forests.
