At 380 million years, Jenolan Caves are thought to be the oldest visited caves in the world. Around two hours drive west of Sydney, ten caves are open to the public. This photo shows the mesmerising beauty of the Orient Cave visited recently with my close and treasured friend Kath. The cave features three exceptionally featured rooms evocatively called the Indian, Egyptian and Persian Cambers. The formation is appropriately called The Curiosity Shop and includes helictites that are the strange formations that grow in all directions defying gravity (and scientific explanation).
