The Limestone Coast is a region located in the southeast corner of South Australia, stretching over approximately 21,000 square kilometres. Its name is derived from the extensive limestone deposits found all over the region, which has helped in the formation of some of the area's dramatic natural features, including sinkholes, caves, and coastal cliffs.
The Limestone Coast holds significant environmental and cultural importance. The region is home to several national parks and conservation areas, including the popular Coorong National Park and Canunda National Park, offering beautiful landscapes and diverse wildlife.
The region is known for its fertile soil, mild maritime climate, and abundance of underground water, making it an ideal destination for viticulture and farming. It is globally recognized for its premium wine production, particularly its Cabernet Sauvignon, Shiraz, and Chardonnay. The area has six designated wine regions, including Coonawarra, Mount Benson, and Padthaway.
The major towns of the region are Mount Gambier, Millicent, Penola, and Naracoorte. Mount Gambier, the second most populous city in South Australia, is notable for its "Blue Lake", which changes colour from grey to intense blue annually.
There are also several sites of cultural and historical significance, such as the World Heritage–listed Naracoorte Caves National Park, which houses some of the world's most important fossil findings.
The Limestone Coast also offers a vast range of recreational activities, including fishing, diving, boating, and hiking. It offers picturesque coastal scenery with long sandy beaches, rugged cliffs, and charming seaside towns.
