THE BLUE LAKE MOUNT GAMBIER
The Blue Lake in Mt Gambier South Australia is an extinct volcanic crater which mysteriously turns into a brilliant azure blue colour during summer from December to end of March while it turns into winter grey from May to November. There are lots of theories as to why it behaves that way. Generally, it is said to be caused by the amount of sun that hits the surface of the lake during summer thus increasing the temperature of the water. This then causes the chemical compound calcium carbonate to precipitate and breakout of the solution enabling micro crystallites to form. The sight from the lookout is breathtaking. The Blue Lake is in Mt Gambier second most populated City in South Australia. This vibrant place is 435 km south of Adelaide City and half-way to Melbourne. The Blue Lake is one of the best stops you should not miss when driving from Adelaide to Melbourne or vice versa.
