Help improve Atlas Obscura by expanding Caiguna Blowhole with additional information or photos.

This unique cavity was formed by weathering of the limestone to form a cave 0.5 to 1.5 meters (1.6-5 feet) deep. Like all caves on the Nullarbor Plain, it breathes; When the air pressure falls, the cave breathes out and when the air pressure rises, it breathes in.

The Caiguna blowhole is one of an estimated 100,000 blowholes scattered across the plain. It has displayed some exceptionally powerful “breathing,” with measurements of air movement at the cave entrance reaching up to 72 kilometers per hour (45 miles per hour).

Know Before You Go

People have littered the cave and surrounding area. Please pick some of this rubbish up and help keep these amazing caves clean for all to enjoy.
