Kiama Blowhole

Kiama BlowholeThe small coastal town of Kiama (New South Wales) has a very distinctive tourist attraction, the Kiama Blowhole. The Kiama Headland is composed of volcanic rock called latite. A volcanic extrusion known as a dykea sheet of rock that formed in a crack in a pre-existing rock body, cuts through the latite. The dyke is composed of a softer rock called basalt. Over millions of years the softer basalt has eroded faster than latite creating a tunnel under the headland. Eventually part of the headland collapsed creating this spectacular spot on the east coast of Australia.

More than 600.000 tourists every year enjoy the splashes of water that, according to the sea conditions, can reach up to 25 meters in the air.
