Less than an hour away of the capital city of Senegal there is an unusual lake. Lake Retba, or Lac Rose is separated only by some narrow dunes from the Atlantic Ocean, and, as expected its salt content is very high. It is salinity compared to the Dead Sea and during the dry season it exceeds it. Its distinct pink colour is caused by the Dunaliella salina bacteria, which is attracted by the lake salt content. The bacteria produces a red pigment in order to absorb the sunlight, thus giving the lake its unique colour. Its colour is especially visible during the dry season, which lasts from November till June.
