The dazzling sapphire waters of Mount Gambier's Blue Lake are one of the most iconic sites on the Limestone Coast. Once an active volcano, the 72-metre-deep crater is now filled with cobalt water which mysteriously changes shade to a deep, turquoise blue during spring. A visit between November to late February will ensure you its famed deep, turquoise blue colour which then fades during the winter months.

3. Little Blue Lake, Limestone Coast

Just minutes out of Mount Gambier, the impressive swimming amphitheatre of Little Blue Lake is surrounded by towering 10-metre limestone walls and boasts crystal-clear fresh water. Fast forward to summer and this geological wonder turns into a swimming hotspot for Limestone Coast locals, with calm, cool waters perfect for lounging on your lilo.

4. Umpherston Sinkhole, Limestone Coast

Cradled beneath the earth's surface lies a real-life Garden of Eden, also known as Umpherston Sinkhole. The ancient limestone walls of this subterranean oasis have been corroding for millions of years, creating the perfect flower pot for a few local green thumbs to toil. The result? A beautiful sunken garden blanketed with flowers, plants, lush green grass and palm trees bursting just above ground level. Appreciate its size and depth from the viewing platforms at the top of the sinkhole, venture down into its depths, along the terraces and behind the hanging vines, or stick around after sunset and meet some of the friendly possums emerging daily at dusk.
