About Hastings Caves and Thermal Springs
A spectacular system of dolomite caves in southern Tasmania featuring extraordinary calcite formations including stalactites, stalagmites, flowstone, and rare coral-like growths called cave coral. The main cave, Newdegate Cave, is among the largest decorated caves in Australia and was formed over 40 million years ago. Adjacent thermal swimming pool fed by a natural spring at a constant 28°C is a popular attraction, especially in cooler months.
