Jenolan Caves

Overview

This limestone labyrinth, set within the remote south of the Blue Mountains National Park, is the world's most ancient open caves system, dating back 340 million years. There are numerous illuminated pathways to explore throughout the 40 kilometres of subterranean palaces, so you'll need to book specific show cave tours.

Visit Lucas Cave to be challenged by more than 1000 steps that deliver you into the belly of the mountain to the system's largest chamber that hums with acoustic vibrations. Marvel at thick drapings of crystal formations and Jenolan's tallest stalagmite, 'Pillar of Hercules', in the Orient Cave, or see every angle of delicate crystal shawls and helictites that seem to defy gravity and grow greedily in every direction within the dreamy Temple of Baal Cave.
