Tickled Pink at Lake Hillier of Western Australia

Also known as the Bay of Isles, Recherche Archipelago is a group of 105 islands and 1,500 islets out of which 64 islands have been explored and named. The famous Pink Lake Hillier is formed on Middle Island, the largest island within the Recherche Archipelago on the south eastern corner of Western Australia. It is 600 meters (2,000 feet) in length and about 250 meters (820 feet) in width and surrounded by thick eucalyptus trees and other vegetation.

What caused the lake to be BUBBLEGUM PINK? Let’s all take a little stroll through biology!

Researchers thinks that it is caused by the presence of the organism Dunaliella salina – a type of halophile green micro-algae especially found in sea salt fields, salinibacter ruber (red bacterium) and few other species of Archaea (in layman terms put simply microorganisms).

Is the colour permanent throughout?

The salinity level of Lake Hillier is 10 times more than the ocean all year round, it might contribute to the conditions where the colour can maintain throughout the year. Hence the answer is yes it is permanent – as the Aussies say “fair dinkum” !!

You may reach by sea or by air, by land it is not possible as the lake is surrounded by thick forest. Although some brave the track. By air is the best way to view as it gives a stunning visual contrast of the pink lake and the blue ocean. Lake Hillier is not the only pink lake in Western Australia, but it is certainly the most consistent and by far the most stunning of the few.
