The Tongariro Alpine Crossing is heralded as the best one-day trek in New Zealand and is regarded as among the top ten single-day treks in the world. Many who complete the 20.2 km (12 mile) journey will tell you the climbs can be steep and the weather unpredictable, though worth it in every aspect. The Tongariro Alpine Crossing is located in the Tongariro National Park - New Zealand's oldest national park and a dual UNESCO World Heritage Site. Tongariro National Park is rich in both cultural identity and dramatic, awe-inspiring natural scenery. Unique landforms, including the volcanic peaks of Ngauruhoe, Tongariro and Ruapehu ensure the Tongariro Alpine Crossing is considered a world-renowned trek.
