There are roughly 110 hot springs and pools throughout New Zealand, including in and around Rotorua, which is renowned for its geothermal activity. This is home to the geothermal reserves of Te Puia, Waiotapu, and Waimangu, with other-worldly landscapes that include bubbling mud pots, geysers, boiling pools, fumaroles, craters, and hot springs. One of the most unique places for a soak is Hot Water Beach on the North Island just south of Mercury Bay along the east coast of the Coromandel Peninsula. You’ll have to dig your own spot for a soak – before and after low tides, your hole will fill up with naturally warm, mineral-filled water. As the water can be as hot as 150 degrees Fahrenheit, you’ll add cold seawater to regulate the temperature.
