This is a marvelous pink lake surrounded by the lush green narrow coastline and washed by the deep blue ocean waters. Is this a sight from a dream? No, it's definitely real and should be put in your must-see list
Best time: October–April
Several lakes all over the world have this unique colour of the pink bubble gum. Hillier Lake is one of such amazing lakes. It is located on Middle Island, off the coast of Western Australia. The lake lies right next to the Pacific Ocean, and only a narrow coastline separates them. The contrast between the pink colour of the lake and the blue ocean creates a truly striking view.
The reason for the colour of the Hillier Lake is still not understood fully. One of the versions says it is the presence of the Dunaliella salina microalgae that contributes to the colour. According to another opinion, the presence of halophilic bacteria in the salt crusts is the reason. But the unique fact is that the colour of the lake doesn't change due to the temperature variation or other factors and stays the same year round. It stays pink even in the bottle.
The water isn't harmful to people's skin and you can even swim in it safely. But the island has been closed for further researches, thus you can't visit it. Everyone willing to see the Hillier Lake can do it only from the air. Scenic helicopter flights operate daily between October to April on the Esperance foreshore.
