Geological wonders abound in Mount Gambier, the heart of the Limestone Coast and second largest town in South Australia. Discover the dazzling sapphire waters of the famed Blue Lake, the local's favourite Little Blue Lake and explore an underground garden of Eden at Umpherston Sinkhole. Pull up a seat at a New Orleans-style jazz bar or for the adventurous, snorkel the crystal-clear waters of the Piccaninnie Ponds which have been filtering through the limestone over thousands of years, or descend deeper at the world-famous dive site Kilsby Sinkhole. Wander down streets dotted with impressive heritage buildings and explore a plethora of shops, cafes and restaurants, while just beyond the town you’ll find day-trip destinations like Robe, Penola and Coonawarra. Fun's changed on the Limestone Coast and it's closer than you think.
