Jenolan Caves

Formed 400 million years ago, the Jenolan Caves make up one of the most extensive and complex underground limestone cave systems in the world. Limestone caves are formed when beds of limestone rock appear near the earth’s surface and begin to dissolve with rainwater. A slow drip, drip, dripping through the soil gradually forms the tunnels and caverns. Of the 300 or so ‘rooms’ that make up Jenolan Caves, 11 are open to the public (bookings essential, 1300 763 311). The tours reveal fascinating flowstone deposits, helictites, columns and lakes. Other caves are found in adjacent Kanangra–Boyd National Park.
