Little Blue Lake
A natural sinkhole lake south of Mount Gambier with deep blue water, where you can dive and swim from platforms. It's a summer hot spot.
Little Blue Lake is a circular sinkhole lake about 40 m across and more than 40 m deep, ringed by steep limestone walls. Steps and platforms lead down to the water. In summer, locals and visitors dive and swim here. The water stays cool, only in the low teens Celsius even at midsummer. It lies about 15 km south of Mount Gambier, near Mount Schank, and can be combined with Mount Schank and Port MacDonnell for a half-day trip. Admission is free, but there are no lifeguards. The water is deep and cold, so know your limits, and swimming alone is not recommended.
