Lake Hillier is a pink-coloured lake on Middle Island, the largest of the islands that make up the Recherche Archipelago off the coast of Esperance.
From above the lake appears a solid bubble gum pink. The lake is about 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 colour comes from a dye created by bacteria that lives in the salt crusts.
Middle Island's pink lake dates back to the journals of explorer Matthew Flinders in 1802. Flinders had climbed Middle Island's highest peak (now known as Flinders Peak) to survey the surrounding waters when he came across the remarkable lake. Middle Island and its pink lake are located in a pristine wilderness. The only way to view this lake is from the air. You can also explore the islands and abundant wildlife of the Recherche Archipelago on a cruise from Esperance.
Pink Lake near Esperance is another pink lake set against a backdrop of some of Australia's most stunning coastal scenery, seven kilometres from the town of Esperance.
In the right weather conditions, the lake turns a soft shade of pink due to the high concentration of algae in the water. For the best views and excellent take a walk to Pink Lake lookout.
The lake has been identified by BirdLife International as an Important Bird Area (IBA) because it supports significant numbers of native and migratory birds.
