The Natural Bridge is a naturally formed rock arch over Cave Creek, a tributary of the [[Nerang River]]. It was formed from a waterfall that 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.<ref>[http://www.goldcoastcity.com.au/t_standard.aspx?pid=1060 Natural Bridge page] {{webarchive|url=https://web.archive.org/web/20060823175856/http://www.goldcoastcity.com.au/t_standard.aspx?pid=1060 |date=23 August 2006 }} (Gold Coast City Council)</ref>

The bridge is in the territory of the local [[Kombumerri clan|Kombumerri]] aboriginal people (a family group of the [[Yugambeh language]] peoples). The first Europeans to find it is said to be timber cutters Alexander (Sandy) Duncan and Din Guinea.

The cave is home to a colony of glowworms (larvae of the insect ''[[Arachnocampa flava]]'') and commercial operators lead night tours into the cave. The ‘light’ seen is produced within the glowworm's body. It is the reaction of four chemicals that produces the cold light or bioluminescence—meaning ‘living light’. Glowworms generate this bioluminescence to lure their prey.<ref>{{Cite web|url=https://parks.des.qld.gov.au/parks/springbrook/culture.html|title=Nature, culture and history|website=Department of Environment And Science|date=26 June 2006 }}</ref> Swimming is no longer permitted to protect the glowworm habitat. This applies to the area bounded by the walking track/circuit. Downstream access to the creek is allowed but the pools are too shallow for swimming. Access to this section of the park is from Nerang-Murwillumbah Road.
