| When the sunlight shines on, the lake surface is more sparkling and attractive than ever. |
The lake is about 600 m long and is surrounded by a sandbar and a dense forest of paperbark and eucalyptus trees. A narrow strip of sand covered with vegetation separates the lake from the southern sea.

| Lake Hillier is located on an island, surrounded by the vast ocean.  |
Unlike other pink lakes around the world, such as Lake Retba and the Salt Lake in San Francisco Bay, scientists have yet to determine the source of Hillier's pink color. However, many scientists speculate that the pink color of the lake is created by organisms called Dunaliella salina and Halobacteria. Another hypothesis is that it is caused by a red bacteria in the salt crust. The color is also not a work of sunlight, as a barrel of water was taken from the lake and the pink color remained the same even when the barrel was moved.

| The special pink color of Lake Hillier remains a mystery that no scientist has been able to explain. |
Except for a few years when people mined salt here, the island and the pink lake remained almost intact. The lake offers visitors a most wonderful sight, it is a natural wonder of the world.
In addition to Hillier, there are some unique pink lakes in the world such as: Lake Retba (also known as Lac Rose) located in the North of the Cap Vert Peninsula, Northeast of the capital Dakar, Senegal. Lake Salina de Torrevieja and La Salina de La Mata are two salt lakes surrounding Torrevieja, a coastal city in Southeast Spain. Dusty Rose Lake is located in British Columbia, Canada and has strange properties. Although the lake has no salt or algae, the water is still pink. Or Masazirgol (also known as Lake Masazir) is a salt lake in the Qaradag region, near Baku, Azerbaijan.
