Lake Hillier is on the largest island in the Recherche Archipelago, Middle Island. It is one of the few naturally pink lakes in the world. Surrounded by eucalyptus and paperbark trees, the lake stretches nearly 600 meters in length and 250 meters in width. The lake is only a few meters deep and is much shallower than many other natural lakes.

The History Of Lake Hillier

While Lake Hillier was no secret to the Indigenous people who lived on the island, it remained a secret to the world until it was documented by Matthew Flinders in 1802. Flinders was a British explorer who saw the lake after climbing the tallest mountain on the island. Flinders also gave the lake its name, naming it after a crew member who passed on before the explorers left the island.

The Pink Mystery

Lake Hillier is famous for its unique pink color. While there are a few other pink lakes in the world, they all change color depending on the season. Hillier is unique because the water stays pink all year-round. This key difference has made Lake Hillier an interesting destination not only for tourists, but for scientists as well.


Why Is It Pink?

No one knows for sure why Lake Hillier is pink, but scientists think they may have found the answer. After studying the lake, they found that it is home to a unique type of algae called Dunaliella salina and red Halobacterium. 

It is believed the interaction between the algae and the bacteria cause the large amounts of salt in the lake to make red dye, and this is what gives Lake Hillier it brilliant pink color.

Lake Hillier’s Unique Ecosystem

Lake Hillier has an incredibly high salt content, almost as much as the famous Dead Sea. Because of this, there are only a few species of bacteria that can survive in the lake. However, even with the high salt levels, Lake Hillier is still a safe place for people to take a dip in.

Life Around The Lake
