 Revenue from tourism was US$303 million in 2014, up from just US$62 million in 2000.The largest contributor to this revenue was mountain gorilla tracking, in the Volcanoes National Park; Rwanda is one of only two countries in which mountain gorillas can be visited safely; the gorillas attract thousands of visitors per year, who are prepared to pay high prices for permits.Other attractions include Nyungwe Forest, home to chimpanzees, Ruwenzori colobus and other primates, the resorts of Lake Kivu, and Akagera, a small savanna reserve in the east of the country.
