Underground the World Heritage Blue Mountains wilderness sets the Jenolan Caves. Dated at 340 million years old, these limestone caves are the oldest on the planet. The underground network extends over 30 kilometres, also making it the largest cave system on earth.
Gordon Mills, a guide of the Jenolan Caves since 12 years ago, tells how the remarkable site came into existence, while explaining the formation of the spectacular crystals.
