Lake Hillier
Lake Hillier is an Australian lake known for its striking bubble-gum pink color, located on Middle Island in the Recherche Archipelago. Its unique hue, which remains year-round and even when bottled, is attributed to a combination of high salinity, salt-loving algae (Dunaliella salina), and pink halobacteria, though the exact scientific explanation remains a mystery.
