Details
The Blue Lake at Mount Gambier is a unique attraction. Water in the lake is exceptionally clear, the quality is very good, but it is hard due to infiltration through limestone, which underlies the district The colour of the Blue Lake changes from dramatically grey to a vivid blue over a few days in late November. Then, after summer the colour gradually fades until the grey winter appearance is resumed. Experience this fascinating tour, which takes visitors in a glass-panelled lift down the original dolomite well shaft, from which water was originally extracted, through a tunnel to see the Blue Lake at close proximity. Learn about the hydrology of Mount Gambier’s water supply and the aquifer system. Hear the interesting stories of local history, European settlement, folklore and aboriginal legend.
