Mountain Lagoon

This small rural settlement is reached from Bells Line of Road. Take the Mountain Lagoon Road turnoff just east of Bilpin and follow it for 11.5 km (2WD). Mountain Lagoon can also be reached from Comleroy Road by 4WD only.

Mountain Lagoon is a very unusual landscape feature - a lake on a mountain top. It is not a volcanic crater, but a depression caused when movements of the Earth pushed up the Blue Mountains and created the eastern escarpment. The pressure on the layers of sandstone was so great that they fractured just behind the escarpment, forming the Kurrajong Fault. The escarpment continued to move up east of the fault, but to the west the plateau lagged behind. Today, the top of the escarpment through Kurrajong Heights is higher than the plateau just to the west.
