February 5 , 2024 164 days 416 0
  • This lake’s waters are virtually devoid of life, with the exception of a few microscopic algae and bacteria.
  • Lake Retba, better known as Lac Rose (the Pink Lake), is located around 35km from the city of Dakar, Senegal, Africa.
  • It sits in a depression with a shoreline 6.5 metres below sea level.
  • The lake is isolated from the sea by about 1km of sand dunes.
  • Its fresh water comes from the seasonal water table in the dunes, which are higher than the lake.
  • Thus, the sea provides most of the lake’s water and all of its salt.
  • The Pink Lake is one of the main tourist destinations in the Dakar region, primarily because of the pink colour of its waters.
