Located north of the peninsula of Cap Vert in Senegal, north east of Dakar, Retba Lake or Lac Rose is a natural visual marvel that has not been manipulated by man. Intense pink color is due to the lake halophilic cyanobacteria found in the water which produces a red pigment to resist salt concentration,however, these bacteria are harmless. Apart from this, Lake Retba has a higher salt content than the Dead Sea, so it allows people to float without effort. It is certainly one of the most amazing places that hosts our planet.
