The Tongariro National Park is a World Heritage site which has the distinction of dual status, as it has been acknowledged for both its natural and cultural significance. The crossing passes over the volcanic terrain of the multi-cratered active volcano Mt Tongariro, passing the eastern base of Mt Ngauruhoe. The 19.4 km walk is renowned for its barren yet beautiful “moon like” volcanic landscape, unusual geological features, visible volcanic activity and views of the surrounding countryside below.
