The theory behind the lake’s radiant colour is because of the large amount of white calcite crystals that form on the surface, which reflect bright blue wavelengths when the sun’s rays hit.

The best time to visit is during November-March on a sunny day, as this is when the water will be the most vibrant

Other than the viewing platforms along the circuit, there are multiple places to view the lake’s beauty:
Including Centenary Tower, Blue Lake Lookout and the Hidden Underpass. This last one results in the most beautiful panoramic view and the safety rail is decorated with engraved locks as if it has become tradition when visited.
