10Lake Hillier, Australia
Lake Hillier, located on Middle Island off the coast of Western Australia, is perhaps one of the most famous pink lakes in the world. This striking bubblegum-pink lake is surrounded by lush green forest and the deep blue waters of the Southern Ocean, creating a mesmerizing contrast. The lake’s color is permanent and does not change when the water is bottled, making it even more mysterious. The pink hue is believed to be caused by the presence of Dunaliella salina algae and halobacteria, both of which thrive in the salty environment. While swimming in Lake Hillier is not allowed due to its remote location, aerial views provide an unforgettable sight.
