LIMESTONE COAST

Where underground wonders and coastal charm collide.

Overview
Stretching along the southern edge of South Australia, the Limestone Coast is a land of contrast and discovery. From the cobalt-blue waters of Mount Gambier’s crater lakes to the sun-drenched vineyards of Coonawarra, this region invites exploration above and below ground. Discover ancient caves, snorkel in sinkholes, or unwind along windswept beaches. It’s a destination rich in history, geology, and rustic hospitality.

See and Do

The local favourite
Dive into the crystal-clear waters of the Umpherston Sinkhole, a sunken garden hidden in a collapsed cave right in Mount Gambier.

A scene of pure natural beauty
Visit the Blue Lake, which shifts to a brilliant cobalt hue each summer, and explore the World Heritage-listed Naracoorte Caves—filled with stalactites and prehistoric fossils.

Adventures in nature
Taste premium wines in Coonawarra’s terra rossa soil, relax on the beaches of Robe and Beachport, or follow the Southern Ocean Shipwreck Trail along this dramatic and lesser-known coastline.
