Experience the natural wonders of Te Aroha Waihou Springs in Waikato, New Zealand. This unique thermal site boasts a bicarbonatated water source and features the scientifically rare Mokena Geyser, which is the only naturally bubbling soda spring hot spring in the world.
Insider tip — Te Aroha Waihou Springs are fed by one of the world's few known hot soda-water geysers, the Mokena Geyser, on the western flank of the Kaimai Range. The naturally carbonated and mildly sulfurous water has attracted visitors since the Victorian era and the heritage bathhouse domain remains one of New Zealand's most peaceful spa precincts. Pair a soak with a walk through the adjacent domain gardens for the full 19th-century experience.
