When people think of Kiama, one of the very first images that comes to mind is the dramatic burst of seawater shooting skywards. The two Blowholes in Kiama, both powerful and fascinating in their own way, are among the most iconic natural attractions on the South Coast of New South Wales. If you’re planning a day trip or adding Kiama highlights to your itinerary, the Blowholes are an absolute must.
What are the Blowholes?
Kiama is home to two blowholes sculpted by millions of years of volcanic activity and relentless ocean force. The larger and more famous of the two sits at Blowhole Point, just a short walk from the town centre and the iconic Kiama Lighthouse. A second, smaller but equally impressive blowhole lies around 2 kilometres south on Tingira Crescent, known as the Little Blowhole.
Both blowholes were created from basalt lava flows about 260 million years ago, long before dinosaurs ruled the Earth. Over time, ocean waves eroded softer rock within sea caves, carving out the channels that allow seawater to rush in and blast out dramatically through the surface openings.
A bit of history
The Blowholes have held cultural significance for thousands of years. Local Aboriginal peoples knew the larger blowhole as Khanterinte, a name that reflects the thunderous sound of the sea as it forces its way through the underground chambers. The wider region’s name, Kiama, is often translated as where the sea makes a noise, showing the deep connection between place and ocean.
European history of the site dates back to 1797, when explorer George Bass first documented the blowhole during his south coast voyage in an open whaleboat. Reports from his journey describe the dramatic sea action and the roar of water that would become a defining feature of the coastline.
The Big Blowhole: Kiama’s headline act
The larger blowhole, usually simply called the Kiama Blowhole, is the most visited natural attraction in the area. Its opening on the rock face measures around 2.5 metres wide, and in the right conditions plumes of seawater have been recorded shooting more than 30 metres into the air.
Best time to see it
There’s no ticket or timetable for the Blowholes. They are active whenever nature feels like putting on a show. That said, the most impressive displays tend to occur when the swell is running from the south-east, creating powerful waves that drive water through the blowhole with maximum force.
Stormy days with strong winds and high ocean swells can deliver the most dramatic action, but many visitors prefer to experience the blowhole on clear days with a gentle breeze, when the display is easier to watch and photograph.
Where to watch from
There are multiple accessible viewing platforms around the Kiama Blowhole, including wheelchair-friendly paths that make it easy to take in the spectacle from various vantage points. The easternmost lookout tends to offer the most complete view of the water plume and dramatic coastal backdrop.
The Little Blowhole: underrated but spectacular
A short drive or a scenic walk along the Kiama Coast Walk leads you to the Little Blowhole. While smaller than its famous sibling, many visitors find it more consistent, especially in different wind and swell conditions. It often performs when the Big Blowhole is quiet, making it a great second stop on your coastal adventure.
The Little Blowhole is best seen when seas are coming from the north-east, an ideal addition to photographers’ itineraries and visitors chasing that perfect ocean shot.
Tips for tourists
Parking and access
- Kiama Blowhole parking: There is dedicated parking near Blowhole Point with space for cars and coach parties, plus picnic areas and public toilets. It’s a short walk from the centre of town and close to the Kiama railway station, so catching the train is also a hassle-free option.
- Little Blowhole parking: Head to Tingira Crescent in South Kiama where there’s a small parking area near the viewing platforms. There’s also plenty of street parking available. Keep in mind the Little Blowhole is slightly more off-the-beaten-path compared to its big sibling, so give yourself a few extra minutes to find the lookout.
Best weather and timing
- Swell direction matters more than tide: The Blowholes are driven by ocean swell and wind direction, not tides. A strong south-east swell usually brings the best performance at the Big Blowhole, while the Little Blowhole likes a north-east swell.
- Seasons: Winter months often bring larger ocean swells and dramatic displays, but calmer days in spring and autumn can also be spectacular and more comfortable for picnics and walks.
- Avoiding peak crowds: Early morning or later in the afternoon can be quieter and softer in light for photography, whereas midday tends to see more tourists.
Safety first
The blowholes are exciting natural features but can be unpredictable. Ocean spray and powerful waves can be dangerous if you stand too close to cliff edges or rocks. Always stay behind safety barriers and supervise children closely.
Combine your visit with more coastal fun
While you’re at Blowhole Point, you can take in other nearby attractions like the Kiama Lighthouse, enjoy a swim at the Blowhole Point rock pool, or explore the scenic Kiama Coast Walk that stretches both north and south from the headland.
Both Blowholes are worth the trip
Few natural phenomena embody the raw power and beauty of the Australian coast quite like the Blowholes in Kiama. With deep geological history, dramatic water displays and simple, free access for visitors, they are an essential experience on any South Coast itinerary.
