ROUGH OR SMOOTH
this has both a hard rock face cavern and a smooth waterfall

The park is part of the Shield Volcano Group of the UNESCO World Heritage–listed Gondwana Rainforests of Australia.

The Natural Bridge is a naturally formed rock arch over Cave Creek, a tributary of the Nerang River. It was formed from a waterfall which undercut a cave beneath the waterfall and dug a pothole on top, until the two joined and the creek flowed through the cave, leaving an arch across the front.
