About this campsite

The Caiguna Blowhole Rest Area offers an intriguing ecological experience set within the expansive Nullarbor, the world's largest karst landscape. Through small cave entrances, visitors can detect a unique phenomenon: varying air pressure that causes noticeable airflow into or out of the caves. Due to minimal annual rainfall, the limestone weathering process is incredibly slow, preserving the vast cave systems. The Rest Area has basic amenities and ample space for most vehicles, making it an interesting stop on any journey through the impressive Nullarbor region.

There is a bin and some information about the blowhole. No other facilities. The Nullarbor is the largest karst (limestone rock) area in the world. It is also the driest, with an average annual rainfall of less than 250mm. As a result, the weathering of the limestone has been much slower. There are some significant cave systems in the limestone of the Nullarbor. When the entrance is small, airflow can be detected through the entrance. The outside air pressure varies according to the weather system that is currently in the area. As low and high pressure systems move over the region, it causes a difference in pressure between the outside and the inside of the cave. As the air equalises by either flowing into or out of the cave, the airflow through the entrance can be significant.
