3Lake Hillier, Australia: The Pink Lake

Lake Hillier, located on Middle Island off the coast of Western Australia, is famous for its striking pink color. Unlike most lakes, whose colors change due to seasonal factors, Lake Hillier’s bubblegum-pink hue remains vibrant year-round. The lake’s unusual color is caused by the presence of algae and bacteria, but the exact mechanisms are still not fully understood.

Surrounded by lush green forests and the deep blue of the Indian Ocean, Lake Hillier creates a surreal visual contrast that feels like nature’s abstract art. Its vivid pink waters are one of the most bizarre and beautiful sights in the world.
