Choose your walk before choosing a map point. Tongariro is a volcanic national park and a World Heritage area recognised for Māori cultural and natural values, says the Department of Conservation (DOC). The famous Tongariro Alpine Crossing is one route within it, not a universal park entrance. The 2017 photograph shows park landscape, not today's track conditions or necessarily the Emerald Lakes. For the Crossing, plan around its Mangatepōpō start and Ketetahi finish rather than a generic pin at the park centre.
A track booking is not a shuttle booking
The DOC booking page recommends a free track booking for anyone using any part of the Crossing; a track booking is needed when using a shuttle or guided service. Arrange the transport separately. The track guidance recommends a shuttle because summer parking is restricted at Mangatepōpō and the walk finishes elsewhere. Decide how you will return before setting off, and do not park on a state-highway shoulder. Check the parking rules for your own date; one season's arrangements are not a permanent promise.
Prepare for alpine and volcanic conditions
DOC describes the Crossing as difficult, exposed and uneven, and does not recommend it for children under ten. From May to late October, snow, ice and avalanche terrain require specialist skills and equipment. Cold, wind and poor visibility can also occur in summer. This is an active volcanic area: stay on the marked track, keep away from steam vents and do not touch or enter the lakes. Respect mountains sacred to Ngāti Hikairo ki Tongariro. Check DOC's current track notices and the weather forecast just before departure. A general park guide cannot establish that the Crossing is safe on a particular day.
