Tantanoola Caves Conservation Park is home to one of South Australia‘s most impressive caves. It’s called Tantanoola Caves, but there’s basically just one main cavern, set into a cliff face. And the cave decorations are the main selling point.
Where is Tantanoola Caves Conservation Park?
Tantanoola Caves Conservation Park is on the Limestone Coast of South Australia. It’s just to the north-east of Mount Gambier, South Australia’s second-largest city. The location on the Princes Highway makes Tantanoola Caves a really handy stop on the Melbourne to Adelaide drive.
Geologists believe that, although the Tantanoola Caves are no longer on the coast, they have been formed by the pounding ocean over the course of centuries. The sea level has retreated over time, leaving behind a cavern full of pebbles, seal bones and shells.
But it’s the cave decorations (or speleothems) that you’re really here for. The dolomite base rock offers pink and brown colours, while dripping water has created sizable stalagmites and stalactites over the years. There are also shawl-like structures and columns that look like supporting pillars.
Guided tours of Tantanoola Caves
Entrance to the Tantanoola Caves Conservation Park is initially by guided tour. The guide shows off the main formations, and explains the geology behind them.
After the guided tour, you’re free to wander the cavern and take photographs. The main cavern is wheelchair accessible, making it one of Australia’s few accessible cave experiences. The Tantanoola Caves tours last about half an hour and can be booked online at parks.sa.gov.au.
What else is there to do at Tantanoola Caves?
Also within the Tantanoola Caves Conservation Park is a picnic area and a clifftop walking trail with panoramic views of the surrounding district. Kangaroos and birdlife are commonly spotted in the area.
Plan ahead, and you can make a day of it on the Limestone Coast, also going snorkelling in the Kilsby Sinkhole.
