Lake Hillier is a stunning pink lake located on Middle Island, which is part of the Recherche Archipelago in Western Australia. Its vibrant bubblegum-pink hue is striking against the surrounding greenery and blue ocean, making it a popular spot for photographers and nature lovers alike. The lake is about 600 meters long and is surrounded by a rim of white salt, adding to its unique charm. Interestingly, the color of the water comes from the presence of certain algae and bacteria that thrive in the saline environment. While it's not safe for swimming due to its high salinity, visitors can still enjoy breathtaking views from above, especially when seen from a plane or helicopter. The contrast of colors and the remote location give Lake Hillier an almost otherworldly feel, making it one of those must-see natural wonders in Australia.
