Description

Arguably the Nullarbor Plains most famous cave, Cocklebiddy Cave was the site of the worlds longest cave diving penetration in 1983. Cocklebiddy Cave is one of many hundreds of caves that dot the Nullarbor karst the largest arid area of limestone in the world. The entrance to Cocklebiddy Cave is an example of a collapsed doline a sinkhole created when the cave roof collapsed to reveal a system of massive underground caverns and more than 6km of underwater passages. Due to unstable rock at the entrance, Cocklebiddy Cave is CLOSED to public entry. Visitors can walk down into the doline to view the entrance, which leads immediately to a large, steep and rocky chamber over 300m long. Do not go beyond the entrance barrier. Cocklebiddy cave is located 12km west of Cocklebiddy Roadhouse and 10km north of Eyre Highway. The highway turnoff and route to the cave are not signposted. The unsealed track from the highway winds northwards across bluebush plain to the cave entrance. It occasionally splits into several tracks in places where there is the risk of becoming bogged when wet, but converges again. Suitable for two-wheel drive when dry.
