Off the south coast of Australia, there is a sight to behold in the form of bubblegum pink water. Lake Hillier is ten times saltier than the ocean, and contains microorganisms that produce red dye. Though scientists don't know the true reason behind the pink colour, they believe it is a combination of the salt content and microorganisms that dye it.
There are very few ways to reach Lake Hillier. The lake is surrounded by a rim of salt, sand, and a dense forest of paperbark and eucalyptus trees. Airplane scenic tours are the most common.
The length is 600 meters long and 250 meters wide. It lies very close to the Antarctic Ocean, separated only by a narrow strip of sand dunes and some vegetation.
The pink colour of this lake is permanent. When transferred to a container, the water does not change colour at all, remaining just as vibrant as it is in the lake. Despite the colour and high salt content, the lake is safe to swim in.
Previously, the lake was used to harvest salt. Now, this is no longer done, and it is mainly used for tourist purposes.
