Hillier Lake, Western Australia on Middle Island is the only vividly pink lake you will find in the world. The coolest thing about this pink lake is that the color is permanent. You can remove the water and place it in another container, and the color will still be pink. From bird’s eye view it appears to be more of a bubble-gum pink, but its a lighter pink from shore. The color remains unexplained, but it is known that it’s not from the algae, much like the kind that is found on the islands down under. The color could be from nacholite deposits as well as red halophilic bacteria in the salt crusts. No verdict on that yet, so we can still say it’s unexplained.
