Mount Gambier, Limestone Coast
Mount Gambier is a geological wonderland, home to extinct volcanoes, dazzling sapphire waters and an underground Garden of Eden. The town’s crown jewel, the famed Blue Lake, was once an active volcano but today, molten rock has given way to a 72-metre-deep lake filled with cobalt water. It’s less-known little cousin, aptly named Little Blue Lake, is equally impressive, and better still you can dive right into its blue depths. This amazing bathing amphitheatre, which is encircled by breathtaking steep 10-meter limestone walls and features crystal-clear fresh water to refresh you after the drive, is a local favorite. The delights of Mount Gambier extend underground in the heart of town, where you may visit Umpherston Sinkhole, a subterranean sanctuary. Thanks to a few local green thumbs, a stunning sunken garden built in a collapsed limestone cave has been blanketed with flowers, plants, and lush green grass. More activities to do in Mount Gambier can be found in our guide.

Tantanoola Caves, Limestone Coast
Hidden beneath an unassuming cliff-face 20 minutes’ drive from Mount Gambier lies a magical cave dripping with glistening stalactites and stalagmites. Once an ancient shoreline, the sea has long since receded leaving behind a 30-metre-wide chamber adorned with pink and brown dolomite crystals. Tantanoola Cave’s impressive interior has been thousands of years in the making with countless hanging stalactites and floor-to-ceiling crystal columns making it one of Australia’s most beautiful caves. Learn about the history and geology of the cave from a local guide before donning your explorer’s hat and delving in to explore the underground wonderland for yourself. This cave is also one of Australia’s few wheelchair accessible caves.
