Geology can be credited not just for the Coonawarra’s world-renowned wines, but also for these natural wonders of the wider Limestone Coast.
Around 45 minutes’ drive from the Coonawarra, Mount Gambier is the best point of entry for those flying to the region, but don’t rush out the door. With its striking cobalt hue, visible generally between November and February, Mount Gambier’s Blue Lake is one of the highlights worth sticking around for. southaustralia.com/products/limestone-coast/attraction/ blue-lake
Still in Mount Gambier, the Umpherston Sinkhole (pictured below) will delight. Known also as The Sunken Garden, the one-time cave is now a lush oasis, complete with the drama of hanging vines plus hydrangeas, agapanthus, ferns and oyster plants. southaustralia.com/products/limestone-coast/attraction/ umpherston-sinkhole
A sunken garden of a different kind, the 65-metre-deep Kilsby Sinkhole is a diver’s paradise, thanks to its impossibly clear water and labyrinth of underwater nooks and crannies. kilsbysinkhole.com
