The thermal water originates from rainwater that fell 180 years ago, which seeped down through fractured rock in the Hanmer Mountains, to a depth of about two kilometres below the Hanmer plains.
When the springs were first discovered, the hot water rose to the surface under its own pressure from a depth of 10 metres. Today, the water has dropped to some 28 metres below the surface level and is pumped to the surface from a borehole. The water is at a temperature of 52˚C when it is first pumped up and the heat is extracted out of the water using a series of heat exchanges until it reaches bathing temperature of between 32-42˚C.
The complex is open all year round even during winter. We have been before when there has been snow on the ground, and I can tell you, we didn't take much time moving between the pools then!
It is another 'must do' and it is a great day out.
