The last two hours involves walking down a long descent on the northern side of a volcano passing along the Ketatahi Hot Springs.
Carry your own drinking water down the hike as most of the natural water is often scalding hot, filled with minerals and dissolved metals making it undrinkable.
It takes at least two hours to walk down the long descent. Mangatepopo is a higher elevation than Ketatahi. So, it adds 200 meters of climbing.
Tongariro Alphine Crossing is filled with adventure, active crater, steam vents, flowing lava, beautiful lakes, and an unforgettable view. This is one of the greatest single-day hike you can undertake in New Zealand.
