The Tongariro Crossing is a full-day hike into a mountain environment. It travels over steep and often difficult terrain and is often subject to severe weather conditions. Although described as a walking track a change of weather for the worse can make the crossing difficult and even dangerous if you are not well prepared. It is important to have the appropriate clothing, equipment and fitness level.
Often described as New Zealand's greatest day walk, the Tongariro Crossing is a challenging journey across a remarkable volcanic landscape. Beginning at Mangatepopo Valley near Wakapapa, the track climbs alongside a stream and around the edges of old lava flows. The age of different lava flows is indicated by the extent to which plants have re-established themselves on the harsh black lava rocks. Near the head of the valley, the Soda Springs are an oasis for the moisture loving yellow buttercups and white foxgloves.
The steep climb from the valley to Mangatepopo Saddle between Mount Ngauruhoe and Mount Tongariro is rewarded by panoramic views, which on a clear day reach as far as Mount Taranaki. The Tongariro Crossing track continues across South Crater to a ridge leading up Red Crater. The smell of sulfur is a reminder that this crater is still active. Red Crater marks the highest point on the Tongariro Crossing. From here a two-hour detour can be made to the summit of Mount Tongariro.
The track then descends to three water-filled explosion craters called the Emerald Lakes. Their brilliant greenish color is caused by minerals that have leached from the surrounding thermal area. The crossing continues over Central Crater to Blue Lake - an old volcanic vent. After rounding the flanks of North Crater, the descent continues through tussock slopes to the forest bush line. The cool, green forest is refreshing on the long descent to the end of the journey. The Tongariro Crossing takes seven to eight hours in the direction described. The opposite direction is more uphill and takes an hour longer.
