Jenolan Caves

It took more than 340 million years for geological processes to carve these vast caverns from the soft limestone of the Blue Mountains, making the Jenolan Caves the oldest open cave system in the world. Fortunately, it’ll take you a lot less time to make the 175-kilometre drive from Sydney to see them for yourself. Currently underway, major upgrades to the caves’ visitor facilities, walkways and lookouts are due to be completed by 2021. In the meantime, there are still breathtaking tours open to the public, revealing the dramatic rock formations, towering stalactites and crystal pools that make the Jenolan Caves one of the state’s most visited attractions.
