Champagne Pool in Waiotapu’s colour?rich geothermal crater
Published on 09/05/2026 at 16:42 | Editorial responsibility: Rafael MĂĽller, Editor-in-Chief AD HOC NEWS
Champagne Pool in the Waiotapu geothermal area south of Rotorua is a terrestrial hot spring where vivid colour bands, rising steam and mineral-rich water share the same crater. Formed in the late first millennium by a hydrothermal eruption in New Zealand’s Taupo Volcanic Zone, it sits within the broader Rotorua region, long associated with geothermal landscapes and M?ori culture.
A volcanic crater filled with effervescent water
Champagne Pool is a large hot spring occupying a volcanic explosion crater within the Waiotapu geothermal system on the North Island of New Zealand. The crater measures around 65 m (213 ft) across and reaches a depth close to 62 m (203 ft), holding tens of thousands of cubic metres of geothermal fluid that circulate between surface and deeper reservoirs.Its crater dimensions The pool lies over an explosion vent where upwelling geothermal water carries dissolved gases and minerals from depth.Explosion vent beneath the pool
The name Champagne Pool refers to the constant efflux of carbon dioxide gas that forms a stream of small bubbles across the hot spring’s surface, reminiscent of sparkling wine in a glass.Efflux of carbon dioxide The surface water stays at a high temperature in the range typical for geothermal springs, while water entering from depth is significantly hotter, reflecting the intense heat generated by magmatic activity beneath the Taupo Volcanic Zone. Champagne Pool’s hot, gas-rich water then spills out across adjacent sinter flats, where it cools and precipitates minerals in thin sheets, creating further patterns of colour.
Mineral colours along the sinter terraces
One of Champagne Pool’s most striking features is the ring of orange sinter that marks the inner edge of the crater. This band owes its colour largely to arsenic sulfide minerals such as orpiment and realgar that precipitate from the geothermal fluid as it flows over the rim.Orange arsenic-rich rim Around and beyond this inner ring, the silica-rich terraces display white, yellow, ochre and darker tones, shaped by changing mineral content and microbial communities that thrive in the hot, chemically distinctive environment.
The water discharged from Champagne Pool spreads over a broad flat coated in siliceous sinter, a fine-grained deposit formed as dissolved silica precipitates from the cooling geothermal water.Siliceous sinter terraces These terraces show bands of green and other colours linked to minerals such as sulphur and iron and to micro-organisms adapted to high temperature and unusual chemistry.Colourful mineral deposits Standing near the pool, the combination of orange rim, coloured terraces and pale steam above the water creates a layered scene in which geology, chemistry and heat all leave their imprint.
Champagne Pool within Waiotapu Thermal Wonderland
Champagne Pool sits inside Waiotapu Thermal Wonderland, a named geothermal visitor area in the Rotorua region of New Zealand’s North Island.Waiotapu Thermal Wonderland Waiotapu forms part of the Taupo Volcanic Zone, a belt of active and recent volcanism stretching between Rotorua and Taup?. Within this landscape, Champagne Pool acts as a focal point where several properties of the system — heat flow, gas release and mineral deposition — are visibly concentrated.
Geological assessments describe Champagne Pool as having formed roughly 900 years ago during a hydrothermal eruption that excavated the crater in the volcanic rocks.Hydrothermal eruption origin In geological terms that makes it a relatively young feature, shaped over centuries as minerals precipitated from its geothermal fluid and built up terraces around the rim.Young geothermal system The pool also contains traces of metals including gold, silver, antimony and mercury in solution, emphasising the link between deep magmatic processes and the chemistry visible at the surface.
Visiting Champagne Pool: what travellers from Western Europe should know
