Tongariro National Park is the oldest national park in New Zealand, located in the central North Island. It has been acknowledged by UNESCO as a World Heritage Site of mixed cultural and natural values. Tongariro National Park was the fourth national park established in the world. The active volcanic mountains Ruapehu, Ngauruhoe, and Tongariro are located in the centre of the park. The main activities are hiking and climbing in summer, and skiing and snowboarding in winter. There is also opportunity for hunting, game fishing, mountain biking, horse riding, rafting and scenic flights. Mount Tongariro and its surroundings are one of the several locations where Peter Jackson shot The Lord of the Rings film trilogy, tours to view these places are commonly arranged by the tour's operators and lodges. The most popular track in Tongariro National Park is the Tongariro Alpine Crossing. Most of the track is also part of the Tongariro Northern Circuit, a two- to four-day tour, which is one of New Zealand's nine Great Walks. Side trips to the summits of Mount Tongariro and Mount Ngauruhoe are possible on these tracks. Another route is the three- to six-day Round the Mountain Track around Mount Ruapehu. Besides these, there are numerous shorter tracks appropriate for day tramps. With this track net, three camp sites, two emergency shelters, nine public and four private huts and the facilities in Whakapapa, the park is well developed for tourism. These tracks also serve as winter routes, as well as the track to the summit of Mount Ruapehu. Rock-climbing is also an option.
