The Natural Bridge is a naturally formed rock arch over Cave Creek (the headwaters 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 cave is home to a colony of glow worms. Swimming is no longer permitted in order to protect the glow worm habitat. This applies to the area bounded by the walking track / circuit. Downstream access to the creek is allowed. Access to this section of the park is from the Nerang-Murwillumbah Road.
On the way: Hinze Dam, newly upgraded with walking track, viewing platform and educational display and kiosk, great freshwater fishing and kayaking.
