Formally created by an act of parliament in 1894 Tongariro National Park is New Zealand's oldest national
park and a World Heritage site as well. Found in central
North Island just south of Lake Taupo are the three
andesitic volcanoes at the heart of the park --
Tongariro, Ngaruahoe and Ruapehu. Together they form
the southern limits of the Taupo Volcanic Zone.
