Lake Hillier in Western Australia is unique because of its color. Found in Middle Island, the lake has pink water. Paperback and eucalyptus trees surround the lake. The trees also serve as a boundary of the lake and the thin strip of shore.
What’s remarkable about Lake Hillier is that scientists can’t figure out the cause of the pink color. The most logical explanation is the presence of Dunaliella salina microalgae. Another explanation is the occurrence of red halophilic bacteria in the salt crusts.
The pink color of the lake’s water is permanent and doesn’t change even when transferred to another container. The salt content of Lake Hillier is ten times that of the ocean and that’s why you can see a salty crust around its edge. Despite its high salt content, the lake is safe for swimming. However, you will not find any living organisms in the pink lake except for microorganisms.
Cartographer and navigator Matthew Flinders discovered Lake Hillier in 1802. He climbed up the highest peak of Middle Island to look at the surrounding waters when he stumbled upon the pink-colored lake.
In the early 20th Century, Lake Hillier was mined for salt. Salt mining was stopped and the lake is now considered one of the natural wonders of Australia. The area around the lake is now a protected area and has a walking trail that goes around the lake’s shoreline.
There are several ways to get to Lake Hillier. One of the most common methods is by helicopter. You can also take a cruise that will take you to Middle Island. Keep in mind that Lake Hillier is not the only pink lake in Australia. Another famous pink lake in the country is Spencer Lake, which is also found in Western Australia.
