Tongariro Alpine Crossing

The one-day volcano walk by which others get measured. The track climbs to Red Crater, its highest point at 1,886 meters, then drops down loose volcanic scree to the startlingly colored Emerald Lakes, with steam vents along the way. It is a long day, nine hours by the conservation department's winter guidance, and in summer there is no visitor parking at the Mangatepopo end, so plan on a shuttle. Fires in late 2025 burned country near the start, now under a restorative rāhui, so stay on the track. The volcanoes here are live, and the department is plain that eruptions can happen at any time. Keep well away from the fumaroles, and when the crossing is flagged as not recommended for the day's weather, take that as the answer.
