If you stand looking out across the vast crater of Lake Taupo in the center of New Zealand’s North Island, you can see three active volcanoes the largest Mount Ruapehu. In fact, New Zealand sits on the tip of the Pacific Rim of Fire, the arc of active volcanoes circling the Pacific Ocean. This fiery geology has resulted in a stunning landscape highlighted by emerald blue lakes and steamy thermal springs & fields. The Thermal Explorer is one of the country’s major touring routes.
