New Zealand: Rotorua – Te Puia Whakarewarewa Thermal Reserve

Te Puia is a sprawling reserve of geothermal activity in Rotorua, its main attraction being the nearly constantly erupting Pohutu Geyser – the largest geyser in the southern hemisphere. The geyser spouts around 20 times per day, shooting the scathingly-hot water up to 30 meter / 100 feet into the air. There are several other geysers in the area, as well as plenty of alkaline hot springs, bubbling mud pots, and other geothermal oddities.
