Hot Water Beach is a beach on the east coast of the Coromandel Peninsula, New Zealand, just south of Mercury Bay. It is approximately 12 kilometres south east of Whitianga, and approximately 175 kilometres from Auckland by car. Its name comes from underground hot springs that filter up through the sand between the high and low water tidal reaches. The beach is a popular destination both for locals and tourists visiting New Zealand. Annual visitor numbers have been estimated at 700,000, making it one of the most popular geothermal attractions in the Waikato region.
