In case you have not imagined, there is a place where the lakes are not blue but a stunning shade of pink!
Western Australia is home to some of the most unique and breathtaking pink lakes in the world. These natural wonders draw visitors from around the globe, enchanted by the surreal beauty that looks like it belongs to a fairy tale. But what makes these lakes pink, and where can you find them? Let's check out the whys of Western Australia's pink lakes.
Lake Hillier, located on Middle Island off the coast of Esperance, is perhaps the most famous of Western Australia's pink lakes. This lake stands out with its bubblegum pink hue, contrasting sharply with the deep blue of the surrounding ocean. The reason for its vibrant colour is still a subject of study, but scientists believe it is due to the presence of a specific type of algae, Dunaliella salina, and pink bacteria known as halobacteria. This isolated lake is not easily accessible, which adds to its mystique. Most visitors view it from the air via scenic flights, allowing them to witness the lake's striking beauty in its entirety. The combination of the pink water, green vegetation, and blue ocean creates an unforgettable visual experience.
Located near the coastal town of Port Gregory, Hutt Lagoon is one of the most accessible pink lakes in Western Australia. Its colour can range from lilac to bright pink, depending on the time of day, the amount of cloud cover, and the salinity of the water. Like Lake Hillier, Hutt Lagoon's colour is attributed to the presence of Dunaliella salina, which thrives in high-salinity environments. Visitors can drive right up to the lagoon's edge, making it a popular spot for photographers and tourists looking to capture the vibrant hues. The best time to visit Hutt Lagoon is during the late morning or sunset when the sun's angle enhances the pink shades of the lake.
Despite its name, Pink Lake in Esperance is not always pink. Its colour has faded over the years due to changes in salinity and other environmental factors. Historically, the lake would turn a vibrant pink during certain conditions, but recent years have seen a decline in this phenomenon. However, efforts are being made to understand and possibly restore its pink colour. Even without its pink hue, Pink Lake remains a beautiful and serene spot, surrounded by scenic landscapes and offering opportunities for leisurely walks and wildlife spotting. It serves as a reminder of the delicate balance in nature that creates such wonders.
The pink colour of these lakes is primarily due to the presence of microorganisms that produce carotenoid pigments. Dunaliella salina, a type of algae, thrives in the high-salinity waters of these lakes and produces beta-carotene, a red-orange pigment. This pigment, combined with the salt content, creates the stunning pink hues. In some lakes, halobacteria, which also produce red pigments, contribute to the vibrant colours.
Western Australia's pink lakes are natural marvels that showcase the unique beauty of our planet. So, why not plan your trip, and prepare to be mesmerized by the pink splendour of these extraordinary natural wonders?
