With up to 35 active geysers, “The Hidden Valley”, or Orakei Korako, lays claim to being the largest geyser field in New Zealand.
The most famous geyser in this wonder area is the Diamond Geyser, whose unpredictable eruptions vary in length from minutes to hours, ejecting a continuous stream of hot water up to 9 metres high.
The valley also offers a number of beautifully coloured terraces, including the Emerald Terrace, the Rainbow and Cascade Terraces and the Golden Fleece Terrace. The Emerald Terrace is the largest of its kind in New Zealand, and , the Golden Fleece Terrace, called Te Kapua in Māori (meaning “The Cloud”) is an impressive 5 metres high and 40 metres long and takes its name from its white crystal-like colouring.
The area also includes the 45-metre long Ruatapu Cave, one of only two caves in the world known to exist in a geothermal field.
