Lake Retba, or Lac Rose

Lake Retba, or Lac Rose, is a stunning pink lake in Senegal, Africa, located to the North of the Cap Vert peninsula.

The lake is obviously named for its bright pink waters, which are caused by the algae Dunaliella salina. The colour appears to be more vivid during the dry season, and as well as being pink, the lake also has a high salinity, similar to that of the Dead Sea, which allows people to float with little effort. Because of the high salinity, little else but Dunaliella salina can live in the lake, and the water is no good as a drinking source. The lake does however serve as a tourist spot and as a salt collection spot- enhancing the local economy.
