Kiama Blowhole

The Kiama Blowhole is a natural coastal geological formation created over millions of years by the erosion of volcanic basalt rock. As ocean waves crash into a deep, narrow sea cave, the water is forced into an opening in the roof of the cave. The resulting build-up of pressure shoots a massive column of water and air high into the sky.

The blowhole is located in the coastal town of Kiama, situated in the Illawarra region of New South Wales, Australia. It sits right on the Kiama Harbour headland, adjacent to the Kiama Lighthouse. It is easily accessible via a short walk from the town center and is adjacent to the Blowhole Point walking track.

The best time to view the blowhole at its most dramatic is during a high tide combined with a southeast swell, which forces more water into the subterranean cave. When these conditions align, the pressurized seawater can be blasted up to 25 meters (80 feet) into the air. However, because it relies entirely on ocean conditions, it can sometimes be inactive during calm, low-tide periods.

No, visiting the main Kiama Blowhole at Blowhole Point is completely free for the public. The surrounding reserve features parking, viewing platforms, and grassy picnic areas that are maintained by the local municipal council. Visitors can also explore the nearby Kiama Lighthouse without paying any admission fees.
