Discover more about Little Blue Lake

Little Blue Lake is a captivating sinkhole located near Mount Schank in South Australia, approximately 20 kilometers south of Mount Gambier. This natural attraction is a popular destination for locals and tourists seeking a refreshing swim in its cool waters. The lake's name originates from its past tendency to turn a vibrant blue, similar to Mount Gambier's Blue Lake, although it now typically maintains a green hue throughout the year. This change in color is possibly due to increased nutrient levels from agricultural fertilizers. The sinkhole itself is roughly circular, boasting a diameter of about 40 meters. Cliffs rise approximately 8 meters above the water, adding to the dramatic scenery. The maximum depth of the lake reaches about 47 meters, with the shallowest point around 25 meters. Access to the water is facilitated by stairs and a floating pontoon installed on the south side. Little Blue Lake is part of the Kanawinka volcanic area, nestled between the dormant volcanoes of Mount Schank and Mount Gambier. The geological formation of the lake is linked to the collapse of underground water-filled chambers following a drop in sea levels during the last glacial maximum. Stromatolites found in the lake suggest its relatively recent formation. While swimming is a popular activity, it's recommended for experienced swimmers only due to the depth of the water. Cliff jumping is prohibited due to safety concerns. Cave diving is permitted only for divers with CDAA Deep Cavern grade certification. Camping is not allowed at the lake or in the car park. The land surrounding Little Blue Lake was designated as a reserve for public recreation in 1986.
