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. The bridge is located in Springbrook National Park in the Gold Coast hinterland of Queensland, Australia. The park is situated on the McPherson Range, near Springbrook, approximately 100 kilometres (62 mi) south of Brisbane. The park is part of the Shield Volcano Group of the UNESCO World Heritage listed Gondwana Rainforests of Australia.
