Nahanni National Park Reserve of Canada protects a portion of the Mackenzie Mountains Natural Region offering the adventurous visitor a wilderness experience. A key feature of the park is the Naha Dehé (South Nahanni River). Four great canyons line this spectacular whitewater river. At Nailicho (Virginia Falls) the river plunges in a thunderous plume. The park's sulphur hotsprings, alpine tundra, mountain ranges, and forests of spruce and aspen are home to many species of birds, fish and mammals. A visitor centre in Fort Simpson features displays on the history, culture and geography of the area. The park was inscribed on UNESCO's World Heritage List in 1978.
