The Kiama Blowholes

  • Formed from basalt lava flows 260 million years ago.
  • Kiama Blowhole Most active in a SOUTH EAST swell.
  • Discovered by local Aboriginals, who called it Khanterinte.
  • First written about by George Bass in 1797.
  • Little Blowhole most active in a NORTH EAST swell.
  • Both are open to viewing by the public (that's you!) at any time.

The name ‘Kiama’ has long been translated as “where the sea makes a noise” – and nowhere is this clearer than at our famous blowholes. The larger, Kiama Blowhole, is located next to the lighthouse. It has a 2.5m wide opening and has been recorded at heights of more than 30 metres!    

About 2km south, the Little Blowhole (on Tingira Cres) is smaller but arguably more consistent, often putting on regular whoosh-tastic displays. Both are located on the Kiama Coastal Walk, with easy parking nearby and ramp access. Have your camera ready!

True geological wonders, Kiama’s blowholes are visited by thousands of tourists each year. Their foundations were formed from volcanic lava flows about 260 million years ago (that’s 100 million years before the dinosaurs). Eventually it was the ocean’s power that created what we see today – eroding the softer strata rock to create the vertical blowhole.
