Kiama Blowhole is no doubt the state’s most famous blowhole, and for a good reason. It's actually the largest blowhole in the world and can spray up to 25 metres in the air under certain sea conditions. Don’t expect to walk away from this natural beauty without getting a little splashback – there's about 50 litres of water getting thrust up through the cave’s angular corridor.
First things first: get your head out of the gutter. We’re talking about ocean blowholes here. These water explosions happen after powerful waves rush into inland sea caves, forcing pressure to go inland and upwards towards the surface.
There’s something so satisfying about seeing a coastal blowhole erupt. Nature puts on a show – and we sit, listening to the rumble of the ocean and waiting for the eruption of misty ocean water spray. Here are some of the coolest blowholes to check out around New South Wales.
