The Nahanni National Park Reserve is a celebrated destination in Canada's Northwest Territories. One of the park's key features is the Naha Dehé (South Nahanni River). Four great canyons line this spectacular whitewater river -- including Virginia Falls. Nahanni National Park Reserve expanded six times its original size last year, and is now approximately 30,000 square kilometers (roughly the same size as Ireland). Explore the spectacular history, geography and landscape of this area, and see why the Falls are such a popular attraction.
