Taupo is a town on the northern shore of Lake Taupo, New Zealand's largest lake, in the central North Island. It is built around the lake's outlet into the Waikato River, the country's longest river.
It is a popular tourist destination due to its lake, boating, trout fishing, geothermal attractions, waterfalls, outdoor activities and proximity to the North Island's highest mountains.The Lake Taupo area is on a volcanic plateau. The lake, famed for its trout fishing and boating, fills the caldera of one of the largest supervolcanoes in the world, in a still active geological region.
About 26,000 years ago, the lake area was a volcano that erupted in an enormous explosion that ejected about 1,200 km³ of material, spreading it over the central North Island and forming the Volcanic Plateau. The resulting depression became Lake Taupo after it filled with water draining off the surrounding hills.
