Yarrangobilly Caves and Thermal Pools
The Yarrangobilly Caves are located in a 12-km-long karst region along the Yarrangobilly River valley in the north of Kosciuszko National Park, New South Wales, Australia. Discovered to British colonists by a cattleman, the Yarrangobilly Caves system includes several independent limestone caves formed over different time periods, from several million to a few hundred thousand years old.
The caves are administered by the National Parks and Wildlife Service. Three lit show caves are regularly open to visitors, two for guided tours and the third for a self-guided tour. The caves complex also includes a 20 metres long and up to 2.5 metres deep 27 °C thermal pool, fed by natural warm-water springs, and a number of walking tracks.
