Lake Hillier, Middle Island, Recherche Archipelago, Australia.

Have you ever see the lake with pink colour? It is Lake Hillier at Australia. It is located at middle land and the size of the lake is as big as 2 football fields.

If you wonder why it is in pink colour, the scientist could not clarify the reason so far. Some of them said that the colour is mostly due to the red bacteria in the salt crusts or maybe it is a dyed organism that present in it. The colour of the lake is permanent even if you put it in a container. The lake's water is extremely salty due to the high concentration salt in the lake. Due to the unusual lake colour, it has already become the unique lake in the world. 

There is no tourism to be here as it has already prohibited to step your foot in. You can only view it from the sky as they provided 2-hour helicopter tour to view the pink colour lake.
