Lake Retba or Lac Rose (meaning Pink lake) lies about some 30 km north-east of Dakar, capital of Senegal and is named for its pink waters caused by Dunaliella salina algae and is known for its highsalt content which is upto 40% in some areas.
The color is particularly visible during the dry season (from November to June) and is less visible during the rainy season (July to October).
The lake was often the finishing point of the Dakar Rally before it moved to South America in 2009.
P.S. There are other Pink lakes in the world such as Pink Lake and Lake Hellier in Australia.
