Lake Hillier is a pink colored lake on Middle Island, the largest of the islands that make up the Recherche Archipelago off the coast of Esperance in Western Australia. From above the lake appears a solid bubble gum pink. The lake is about 1969 feet (600 meters) long, and is surrounded by a rim of sand and dense woodland of paperbark and eucalyptus trees. A narrow strip of sand dunes covered by vegetation separates it from the blue Southern Ocean. No-one fully knows why the lake is pink. Scientists speculate that the color comes from a dye created by bacteria that lives in the salt crusts.
