Tongariro is a massive complex of volcanic cones and craters formed by eruptions from at least 12 vents over more than 275,000 years. Erosion during the last Ice Age has worn away what was once a substantial mountain into the world famous hiking destination that it is today. The complex includes Ngauruhoe volcano which is described separately here.
Within the landscape of ash, lava flows and erosion features, Tongariro has mineral springs and fumaroles (steam vents) at Ketetahi Springs, the Red Crater and Te Maari craters. These are part of New Zealand’s highest geothermal system which underlies parts of the volcano.
The Red and Te Maari craters were previously active in the 1800’s. The Te Maari area has become active again in 2012.
Altitude, steep slopes, ‘fresh’ volcanic material and erosion prevent vegetation growing on most parts of the Tongariro complex. Some craters have filled with water to create the spectacular Blue Lake and the Emerald Lakes. Check out our video of the landscape features of Tongariro here.
