When the molecules of water absorb the red color elements in the light spectrum, the liquid turns blue. This was the normal understanding about the water bodies of the earth until the discovery of the first pink lake in the world – Lake Hillier. At first, when the mystery became difficult to unravel, settlers nearby found that the extraction of salt was a better use for the strange body of water.

Over the years, scientists have carried out several types of research to understand the facts behind the unique lake and even though it is still a mystery, the beautiful bubble-gum-pink-color of Lake Hillier remains a unique and natural creation of nature that baffles many. These and the fact that the lake is also the most popular pink lake in the world make it worth visiting.


About Lake Hillier

Lake Hillier is a salt lake located in Middle Island on the Recherche Archipelago, Western Australia. The lake was first discovered in 1802 by Mathew Flinders; an English navigator and cartographer, making it the first discovered pink Lake in the World. Lake Hillier is 600 meters long and 250 meters wide, covering a total surface area of 37 acres. Beside the lake is the deep blue Indian Ocean which is only separated from the lake by a thin shore which is surrounded by a dense forest of Eucalyptus and Paperbark trees.

The Lake’s Pink Color

The unique pink color of Lake Hillier is still subject to research; however, it is currently believed that the presence of high amounts of bacteria and microorganisms in the lake’s water is the main cause of its pink color. Several scientists agree that the presence of Dunaliella Salina in the water might be the greatest contributing factor to the Lake’s pink color and a research project carried out by The Extreme Microbiome Project has confirmed the presence of Dunaliella Salina in the Lake as well as other bacteria such as - Dechloromonas aromatic and Salinibacter ruber. The Extreme Microbiome Project is a part of the Association of Biomolecular Resource Facilities and The Metagenomics Research Group.

One interesting fact about the beautiful lake is that the color of the water stays pink even when it is transferred into a container.
