Champagne Pool is a hot spring that was formed 900 years ago by a hydrothermal eruption and is located within the Waiotapu geothermal area in the North Island of New Zealand. Its name comes from the permanent efflux of carbon dioxide gas, which is similar to a glass of bubbling champagne.
The vibrant colors of this crater come from a rich deposition of minerals and silicate. It measures 65 m in diameter and is 62 meters deep. Near the surface the water temperature is 74°C.
The excess water that flows out of the Champagne pool feeds another geothermal pool called Artist’s Palette. From there, the water flows over the silica mud flats to Primrose Sinister Terrace and down Primrose Terrace, creating silica deposits.
