Lake Hillier is an incredibly beautiful lake that lies in Australia. The lake is pink and red because of the microorganisms Alga Dunaliella Salina. The lake is pinker when the sea breeze (during dry season) carries the salt entering into the lake. In the night of full moon the lake appears in a bright red color due to the scattering effect of the moon light. If you want to see the lake, you should visit the lake in January to March when the weather is dry.
