Champagne Pool in Rotorua’s mineral?rich geothermal crater
Published on 09/09/2026 at 17:03 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Champagne Pool in the Waiotapu geothermal area south of Rotorua is a broad hot spring where vivid colour bands, rising steam and mineral?rich water occupy a single volcanic crater. Formed in the late first millennium AD by a hydrothermal eruption within New Zealand’s Taupo Volcanic Zone, it has become one of the most recognisable geothermal features on the North Island.
A volcanic explosion crater filled with geothermal water
Champagne Pool lies within the Waiotapu geothermal system on New Zealand’s North Island, in a visitor zone widely known as Waiotapu Thermal Wonderland.Champagne Pool lies within the Waiotapu geothermal system The hot spring occupies a volcanic explosion crater created by a hydrothermal eruption roughly 900 years ago, a comparatively recent event in geological terms.a hydrothermal eruption roughly 900 years ago The crater is about 65 m (213 ft) across and reaches a depth of around 62 m (203 ft), giving the pool a substantial volume of geothermal fluid held within the basin.about 65 m across and 62 m deep
The water in Champagne Pool is heated by upwelling geothermal fluids beneath Waiotapu. At the surface, temperatures sit close to boiling for freshwater, with measurements near 73–74 °C, while inflowing thermal water at depth has been recorded at significantly higher temperatures.surface temperatures sit around 73 °C Bubbles of gas rise continuously through this hot water, giving the pool its name: the visible efflux of carbon dioxide resembles a glass of sparkling wine.
Mineral colours, steaming water and a sinter terrace
Visually, Champagne Pool is defined by the contrast between jade?green water and an orange mineral rim that encircles much of the crater. The distinctive orange band is created by the deposition of arsenic sulphide minerals, chiefly orpiment and realgar, which precipitate from the geothermal water at the edges.orpiment and realgar create the orange rim These minerals sit alongside traces of gold, silver, mercury and antimony, all carried in solution and left behind as the water cools.
Beyond the crater itself, water discharged from Champagne Pool spreads across a flat, mineral?rich terrace known as a sinter apron. The surface is coated in silica and other deposits, creating a pale, hard crust marked by streaks of colour linked to changing mineral concentrations and heat?tolerant micro?organisms.water discharged from Champagne Pool flows across a sinter flat Steam rises steadily from the pool, drifting across this terrace and reinforcing the sense that the landscape is shaped as much by chemistry as by topography.
Champagne Pool in the Rotorua geothermal landscape
Champagne Pool forms part of the wider Rotorua geothermal region, where hot springs, fumaroles and steaming ground reflect the underlying activity of the Taupo Volcanic Zone.part of the wider Rotorua geothermal region Waiotapu Thermal Wonderland presents this activity along marked routes, with Champagne Pool acting as a focal point among terraces, mud pools and other hydrothermal features. The combination of scale, colour and continuous gas efflux gives this single crater a particularly striking presence within the landscape.
As a terrestrial hot spring rather than a lake, Champagne Pool sits directly over an explosion vent in the volcanic field.Champagne Pool lies over an explosion vent The surrounding countryside includes forest, pasture and other geothermal areas between Rotorua and Taup?, with Mount Tarawera and a string of volcanic lakes further north providing additional context for the pool’s origin. The setting underlines how closely Champagne Pool is tied to regional geology rather than to any individual human intervention.
Visiting Champagne Pool: what travellers from Western Europe should know
- Champagne Pool lies within Waiotapu Thermal Wonderland in the Rotorua district of New Zealand’s North Island, reached overland on the main route between Rotorua and Taup?.
- Paths in the Waiotapu geothermal area are constructed on firm ground and boardwalks, but surfaces can be uneven and exposed, with low barriers beside geothermal features.
- Champagne Pool sits in a geothermal park surrounded by other features, so a visit involves walking on marked tracks through an area of steaming ground.
- The official language is English and the currency is the New Zealand dollar.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.

Where is Champagne Pool located?
Champagne Pool is a hot spring in the Waiotapu geothermal area on New Zealand’s North Island, south of Rotorua in the Taupo Volcanic Zone.
What can visitors expect when viewing Champagne Pool?
Visitors see a broad crater of steaming, green water with an orange mineral rim, surrounded by silica?rich terraces and other geothermal features along marked paths.
What makes Champagne Pool distinctive among geothermal springs?
The combination of near?boiling water, continuous carbon dioxide bubbling and mineral colours including orange arsenic sulphide deposits gives Champagne Pool a striking and immediately recognisable character.
