Trek Tongariro National Park — Central Plateau, New Zealand

The Tongariro Alpine Crossing

A single spectacular day across an active volcanic landscape — steaming craters, red cinder ridges and the vivid Emerald Lakes — often called New Zealand's finest day walk.

Duration: 1 days
Distance: 19.4 km
Ascent: 765 m
Difficulty: Hard
Best season: Best November–April (summer); winter needs alpine experience

The Tongariro Alpine Crossing traverses the flank of an active volcano in the heart of New Zealand’s oldest national park, a dual World Heritage site sacred to Ngāti Tūwharetoa and Ngāti Hikairo. In 19.4 km it climbs from a tussock valley over the shoulder of Mount Tongariro, past the perfect cone of Mount Ngauruhoe, to the raw colours of the Red Crater and the mineral-bright Emerald Lakes, before a long descent to the north.

Despite being a day walk it is a serious alpine route: it is fully exposed, the weather can turn violent within minutes, and the terrain includes loose scoria and active geothermal ground. It should only be attempted in fair conditions with proper gear.

Getting there. The crossing is a one-way walk, almost always done south to north from the higher Mangatepopo end to Ketetahi. A car left at either end will be on the wrong side, so nearly everyone uses a shuttle from Whakapapa, National Park Village or Turangi. A parking time limit applies at the Mangatepopo trailhead.

Season & conditions. It is best walked from November to April, when the track is snow-free; outside summer it becomes a mountaineering trip needing ice axe, crampons and experience. Check the volcanic alert level and the mountain forecast before you set out.

Good to know:

The highest point is the Red Crater at 1,886 m; the descent to the Emerald Lakes below it is on steep, loose scoria.
There is no reliable water and no shelter from weather on the exposed central section — carry everything you need.
