Discover South Australia’s Limestone Coast

Where ancient landscapes, world‑class wine and coastal wilderness meet

The locals like to say it took 26 million years to make the Limestone Coast—and when you see it for yourself, you’ll agree it was time well spent. This remarkable region of South Australia stretches from the windswept Coorong at the Murray River mouth to the lush riverlands of the Glenelg. Formed from layers of ancient marine life settling on the sea floor, the Limestone Coast is a living museum of geology, culture and natural beauty.

Here, 20 sites of national or international significance sit within a single region. Crystalline lakes fill volcanic craters. Prehistoric fossils lie preserved in World Heritage‑listed caves. Saltwater lagoons shimmer beneath vast skies. And some of Australia’s most celebrated wines grow in the rich, red soils of Coonawarra.

This is the traditional home of the Ngarrindjeri and Booandik peoples, whose deep connection to land and water continues to shape the spirit of the region. Their stories, along with the pioneering history of early settlers, echo through every dune, forest and township.

A Landscape of Wonders

The Limestone Coast is a place where nature performs on a grand scale.

• Mount Gambier’s Blue Lake transforms into a brilliant cobalt each summer, filling the crater of a dormant volcano with an almost surreal glow.
• The Pool of Siloam at Beachport, seven times saltier than the sea, offers buoyancy so strong you’ll float effortlessly.
• Naracoorte Caves, a UNESCO World Heritage Site, cradle half‑million‑year‑old megafauna fossils—giant marsupials frozen in time.
• The Coorong, a long, shimmering chain of saltwater lagoons, is a sanctuary for more than 80 bird species and a dreamscape for photographers, anglers and 4WD adventurers.

Every corner of the region reveals something extraordinary, from towering dunes and rugged coastlines to sinkholes, wetlands and volcanic plains.

Wine, Culture and Stories That Shape a Nation

The Limestone Coast isn’t just about natural beauty—it’s also a place of remarkable human achievement.

• Coonawarra, Australia’s premier red‑wine region, is famed for its narrow strip of terra rossa soil that produces some of the world’s most elegant cabernet sauvignons.
• Nearby Wrattonbully, Mount Benson and Padthaway offer boutique cellar doors, cool‑climate varietals and warm country hospitality.
• In Penola, history comes alive in the footsteps of Saint Mary MacKillop, Australia’s first saint, whose legacy of compassion and education began here.

Heritage is celebrated proudly, and new stories continue to unfold in every vineyard, gallery and coastal town.
