Port MacDonnell, South Australia - Rugged Coastlines on the Edge of South Australia

Port MacDonnell is a small but fascinating fishing village on South Australia’s Limestone Coast, surrounded by dramatic coastline, pristine beaches and rich maritime history. Located 466 kilometres south-east of Adelaide, it proudly holds the title of the southernmost town in South Australia and is home to the state’s largest rock lobster fishing fleet.

With its working harbour, windswept clifftops and nearby natural wonders, Port MacDonnell is an ideal base for exploring some of the Limestone Coast’s most iconic landscapes.

Port MacDonnell Maritime Museum

To understand the town’s strong connection to the sea, a visit to the Port MacDonnell Maritime Museum is a must. This small but engaging museum tells the story of the region’s fishing heritage, early settlement and the many shipwrecks that lie along this treacherous stretch of coastline. Displays highlight the evolution of the rock lobster industry and the lives of the fishermen who have worked these waters for generations.

Cape Northumberland

Just a short drive from town lies Cape Northumberland, the southernmost point on mainland South Australia. Here, rugged rocky outcrops meet the Southern Ocean, creating a wild and windswept landscape that feels wonderfully remote. Take time to wander along the clifftops and scan the rocks below — seals are often spotted resting along the shoreline, especially during calmer conditions. The views here are raw, powerful and unforgettable.

Exploring the Natural Wonders Nearby

Port MacDonnell is perfectly positioned for day trips to some of the Limestone Coast’s most remarkable natural attractions.

Ewens Ponds - Crystal Clear Limestone Ponds

Ewens Ponds are spring-fed limestone ponds renowned for their crystal-clear water and delicate underwater plant life. Snorkelling or diving here feels like floating through an underwater garden, with visibility often exceeding 40 metres.

Access is strictly controlled to protect the environment, and bookings are required through SA National Parks, with entry fees applying.

Little Blue Lake - A Great Place to Cool Down

The Little Blue Lake is a striking, water-filled sinkhole with vivid blue tones that change depending on the light. Once part of a former mine site, it is now a popular swimming spot for locals and visitors looking to cool off on warm days. There are stairs and a floating pontoon to make water access easier, though the water can be very cold year-round.

See the Views from the Top of Mount Schank

Rising from the surrounding farmland, Mount Schank is a 100-metre-high dormant volcano with a well-maintained walking track to the summit and around the rim.

From the top, you’ll enjoy wonderful views into the crater itself and sweeping vistas across the countryside towards Port MacDonnell and the coast. It’s a short but rewarding walk that offers a fascinating insight into the region’s volcanic past.

Browns Bay - Beautiful Beach

Browns Bay is a peaceful coastal spot with a long stretch of white sand and crystal-clear blue water. It’s a great place for fishing, swimming or a quiet beach walk, away from the crowds. For travellers in motorhomes or vans, Browns Bay also offers 24-hour camping in the car park for fully self-contained vehicles, making it a popular overnight stop.

Piccaninnie Ponds - Amazing Limestone Pond

Nearby Piccaninnie Ponds Conservation Park is recognised as a wetland of international importance. Like Ewens Ponds, it offers world-class snorkelling and diving through submerged tunnels, aquatic plants and limestone formations. Visitors can explore the spectacular underwater world by guided snorkel or dive tours, with bookings and permits required to help preserve this fragile ecosystem.

Why Visit Port MacDonnell?

Port MacDonnell offers a unique mix of working fishing village charm, wild coastal scenery and world-class natural attractions. From seal-spotting at Cape Northumberland and snorkelling in crystal-clear sinkholes to swimming in volcanic lakes and learning about maritime history, there’s an incredible amount to explore in and around this small town.

As part of the Limestone Coast, Port MacDonnell pairs beautifully with nearby destinations such as Mount Gambier, Ewens Ponds, Piccaninnie Ponds and Beachport, making it a memorable stop on any South Australian road trip.
