Tongariro National Park is a World Heritage Park and one of the oldest National Parks in the world. The park contains 3 active volcanos that are situated in a desert like landscape. The area gets regular snowfalls in the winter and home to most of the ski fields in the North Island. Mt Ruapehu is the largest volcano and last erupted in 1995 and 1996. A conical volcano called Mt Ngauruhoe is located next to Ruapehu and is the location for the Tongariro Crossing. This walk is a tough one day trek that comes highly recommended, and shows off the best that this park has on offer. National Geographic has classed this walk as one of the top 10 one day walks in the world.
