About Blue Lake

Occupying one of the extinct volcano craters of Mount Gambier, Blue Lake is the making of something magical. The city's natural reservoir, has an area of 70 hectares and an average depth of 77metres. But it's the colour that really draws the crowds. The waters of this limestone-walled crater lake mysteriously change colour with the seasons -a sombre blue during the winter months, with an intense deep turquoise during the warmer seasons. Since Blue Lake supplies water to Mount Gambier, it is not for swimming, but tours are run around the lake at close proximity.
