Blue Lake

Blue Lake is a stunning volcanic crater lake that sits on the outskirts of Mount Gambier, Australia. Its intense, vibrant blue colour is a natural phenomenon that shifts to a deeper cobalt in summer, drawing visitors from around the world. The lake is a sacred site for the local Bunganditj people, and its waters are remarkably clear, offering a unique blend of natural beauty and cultural significance. Whether you're a photographer chasing the perfect shot or a traveller seeking a peaceful spot to soak in the scenery, Blue Lake is an unforgettable stop in South Australia's Limestone Coast region.

Highlights & What to See

• Lake Viewing Platforms: Walk along the dedicated paths and platforms that circle the lake, offering panoramic views of the water's brilliant colour against the surrounding volcanic landscape.
• Pump Station & Historic Sites: Visit the historic pump station, which once supplied water to the region, and learn about the lake's unique geology and cultural importance through interpretive signs.
• Wildlife Watching: Keep an eye out for local bird species, including ducks and swans, that frequent the lake's edges, as well as the occasional kangaroo in the nearby bushland.
