Caiguna Blowhole

A hidden attraction in the Nullarbor Plain, this cavernous blowhole provides a sneak peek to what lies beneath the rocky Australian ground. The Caiguna blowhole, just like Nullarbor caves, breathe more vigorously than all the other caves in Australia – in fact, air movement at cave entrance has been measured to be around 72 kilometres per hour. As you get closer the the blowhole, you can feel the earth breathing through the air currents, which, according to Aboriginal legends, were believed to be the breath of spirits. You will also see that the Caiguna blowhole is connected to a tiny cave that has roughly 1.5 metres clearance. These blowholes on the Nullarbor have been formed by both chemical and physical weathering processes through underground cavities.
