Tongariro Alpine Crossing is a 11.9 mile heavily trafficked point-to-point trail located near the city of Whakapapa that features a lake and is rated as difficult. The trail is primarily used for hiking, nature trips, and birding and is accessible year-round.
No permit is needed for the one-day Tongariro Alpine Crossing hike. However, transportation arrangements must be made for both ends of the hike. You must also be mindful of shuttle pick-up times if you decide to summit Mt. Tongariro or Mt. Ngauruhoe (both cannot be done within the same day). There are sections of the hike that are considered active volcano areas.
