Pindar Cave
Pindar Cave is a geological formation which appears as a massive concave of overhanging sandstone rock. It is located west of Woy Woy which is north of Sydney, Australia in Brisbane Water National Park. Although it is named as a cave, the whole formation is an overhang. It is large enough for sixty walkers to camp overnight under its shelter away from wet weather.
