The Tongariro Northern Circuit, one of the New Zealand Great Walks, is a three- to four-day tramp in Tongariro National Park, New Zealand. The hike includes the Tongariro Alpine Crossing, a day's march that incorporates the Northern Circuit's most stunning scenery. The complete trail forms a 50 kilometres long loop trail that circumnavigates Mount Ngauruhoe. Approximately 7,000 trampers complete the walk each year. This compares to the approximately 25,000 who walk only the Tongariro Crossing section.
