It took more than 340 million years for geological processes to carve these cathedral-esque 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.
Time Out tip: If the subterranean splendour of the caves only whets your appetite for yet more nature, Kanangra-Boyd National Park is just a 10-minute drive away, where you’ll find a spectacular look-out point with views of the Kanangra Walls and Mount Cloudmaker.
