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.
A few words from Blue Lake

Whilst offering many awe-inspiring scenic spots of Mount Gambier and its volcanic crater, the Blue Lake also boasts a vibrant cobalt blue colour during the months of December through to March each year. From April through to November, the lake turns to a darker steel grey colour. There are a number of theories behind the mysterious colour change of the water, but it generally accepted that the change in colour has something to do with the water temperature of the Lake.
