Known as The Blowhole, this diversion tunnel was built by miners in the 19th century to divert water from a section of Sailors Creek. This diversion cut off a loop where the remaining dry creek bed was then extensively worked for gold. 

The gold diversion tunnel has created a pretty little man-made waterfall with a shallow swimming hole beneath it. 

When the creek is flowing from winter to early summer, water rushes through the tunnel and falls into a small pool below before continuing down the scenic Sailors Creek. 

Walk to The Blowhole

From the gravel parking area, a fenced walking track heads down to the edge of the gorge, then stairs bring you down past the lookout to the waterhole at the bottom. 

Lookout platform at The Blowhole

The lookout platform overlooks the tunnel and offers a great view down over the waterfall, waterhole and creek beyond. 

Visitor facilities at The Blowhole

While there are no facilities such as picnic tables, seats, etc, there is a pretty stone wall alongside the waterhole which provides plenty of space to sit down.

Swimming at The Blowhole

Swimming is allowed here, but be aware that the water is shallow and there may be submerged objects. Do not dive. 

This is a great place to bring inflatable pool toys and relax, floating on the water. 

When is the best time of year to visit The Blowhole

The best time to visit for water flow is winter/spring, this spot will typically dry up in summer. During dryer parts of the year, you will be able to get a good look at the diversion tunnel - do not attempt to enter the tunnel while water is flowing.

Are dogs allowed at The Blowhole?

Yes, dogs are permitted here (on lead).
