Australia's famous pink Lake Hillier is a sight to behold. Discovered in 1802 by a Royal Navy explorer its strawberry milkshake color is awe-inspiring. Lake Hillier is situated in near the coast of Middle Island in the Recherche Archipelago to the south of Western Australia. Exactly what causes the lake in Australia to be pink is up for debate but is probably to do with the microorganisms that make Lake Hillier their home. Today it's a protected nature reserve but can be visited under special circumstances. It's best to view it from the air in any case.
