What Makes Pink Lake Pink? Can You Swim In The Pink Lake?

Australia has a number of gorgeous lakes that look like they belong in a cotton candy dreamworld and are very photogenic and very pink. On Middle Island, off the coast of Western Australia, Lake Hillier is arguably the most well-known and Instagrammable attraction. However, can we swim in the pink lake? Let’s explore this.

Why Is The Pink Lake Pink?

It has been a mystery for a while, but the solution has now been found. Dunaliella salina, a type of algae that thrives in salty environments like pink lakes, was discovered to be present in pink bodies of water like Lake Hillier. The unusual hues of these lakes are a result of the carotenoid red pigments secreted by Halobacteria and d. salina. The Dead Sea is home to the same kinds of algae.

Does Life Exist In These Lakes?

The only living things in these lakes are microorganisms like red Halobacteria, which is found in the salt crusts, and Dunaliella salina, red algae that contribute to the lake’s high salt content and produce a red dye that gives the lake its color.

Can You Swim In The Pink Lake?


While it is possible in theory to swim in a pink lake, it is not recommended due to the high salt content of the water. Additionally, at least one park website encourages guests to leave the park in the same condition that they found it. Therefore, it is best to stop swimming in this lake in order to preserve these natural wonders for future generations.
