Champagne Pool is a prominent geothermal feature within the Waiotapu geothermal area in the North Island of New Zealand. The name ‘Champagne Pool’ is attributed to the large amount of carbon dioxide (CO2) found in the pool, similar to a glass of bubbling champagne. The hot spring was formed 900 years ago by a hydrothermal eruption. Its crater is around 65 m in diameter and it has a maximum depth of 62 m.
