Lake Hillier sits on the edge of Middle Island, which is off the coast of Western Australia. It's known for its vibrant pink color, which is due to the presence of the algae Dunaliella salina. It causes the lake's salt content to create a red dye, which helps produce its bubble gum color. And despite the high salt levels, Lake Hillier is safe to swim in. Hillier also has a purple-ish lake sibling. Hutt Lagoon, in Port Gregory on Western Australia's Coral Coast, has a large amount of Dunaliella salina, too. Depending on the season and the amount of cloud coverage, Hutt Lagoon can be different colors, ranging from red to pink to lilac.
The colors of Lake Hillier and Hutt Lagoon are truly magical. Lake Hillier’s bubble gum pink is all thanks to the unique algae and high salt content, while Hutt Lagoon’s color shifts from pink to lilac depending on the season. It’s amazing how nature creates such vibrant, unexpected beauty! 
It would be amazing to swim in a pink lake, haha, although it's kinda scary. 
I would love to visit those two lakes someday.
