What is the Kiama Blowhole?
The Kiama Blowhole is a natural blowhole in the coastal town of Kiama, south of Sydney in New South Wales. When waves surge into a sea cave, water is forced through a hole in the rock and shoots high into the air.
The blowhole formed in volcanic rock called latite, which was cracked and eroded by the sea over thousands of years. The cave and opening created a natural funnel for the waves.
Spray can reach heights of up to about 25 metres when conditions are right. The best displays usually happen when there is a large southeast swell.
Visiting Kiama
The blowhole is next to the Kiama Lighthouse, built in 1887, and a short walk from the town center. At night, the blowhole is lit up, adding to the spectacle.
Kiama also has a smaller blowhole, known as the Little Blowhole, which some visitors find even more active on certain days.
The town is a popular day trip from Sydney and lies on the Grand Pacific Drive. Kiama's beaches, coastal walks and seaside cafes make it a favorite weekend destination. Visitors should stay behind safety fences, as waves can be dangerous.
