Mokena Geyser and Te Aroha Domain

The Te Aroha Domain is a lovely Edwardian spa park at the foot of Mt Te Aroha, with restored bathhouses, gardens and tea rooms. Behind the mineral spas is the Mokena Geyser, the world's only known hot soda-water geyser. It erupts about every 40 minutes, usually reaching 3 to 4 m.

Te Aroha Mineral Spas offers private hot soda-water spa pools, which have been used since the 1880s, and the Leisure Pools next door are heated by the springs. The domain is free to walk around. For a view over the Waikato and Hauraki Plains, walk up Mt Te Aroha: the track starts behind the domain (allow about 3 hours to the summit).
