It has a pothole entrance, a vertical extent of 26m (85feet), and a length of 270m (890feet), with some large dry chambers.
Moondyne Cave was discovered in 1881 by Joseph Bolitho Johns, who had formerly been the bushranger known as Moondyne Joe.[3] It was first opened for public viewing in 1911. Guided tours ended in 1959, but it was reopened in 1992 after undergoing restoration.
