Devil's Cauldron

Devil's Cauldron is a major geothermal feature within the Hell's Gate Geothermal Reserve — known in Māori as Tikitere — located near Rotorua on New Zealand's North Island. The reserve is open to the public with an entrance fee and features a network of walking paths and viewing platforms positioned around the active thermal features.

The bubbling mud pool is formed when acidic geothermal water, heated by magma deep beneath the Taupō Volcanic Zone, rises and chemically breaks down the surrounding volcanic rock into a clay-rich slurry. The continuous flow of gas and steam from underground causes this viscous mud to churn and bubble at the surface.

Visitors can safely observe Devil's Cauldron from designated boardwalks and railings maintained by the Hell's Gate reserve. The surrounding ground outside marked paths can be dangerously thin, hot, and unstable in geothermal areas, so staying on the official walkways is essential for safety.

Yes, the Tikitere geothermal area has long been significant to local Māori, particularly Ngāti Whakaue, who have used the thermal waters and mud for cooking, healing, and bathing for centuries. The reserve now offers guided cultural tours and spa treatments using geothermal mud that draw on this heritage.
