Lake Retba
Dakar
Lake Retba, also called Lac Rose, is a unique natural salt lake situated about 35 km northeast of Dakar, Senegal. Its distinctive pink color is caused by the algae Dunaliella salina, which produces a red pigment to capture sunlight, especially vibrant during the dry season from November to May. The lake's high salinity, reaching up to 40%, allows visitors to float easily, similar to the Dead Sea. Salt harvesting is a vital activity here, with thousands of collectors working daily to extract about 38,000 tonnes annually, supporting local fisheries and traditional Senegalese cuisine such as thieboudienne. The lake faced severe flooding in 2022, which temporarily disrupted its iconic color and local economy, but it has since partially recovered. Lake Retba is also notable for its ecological resilience, with species like blackchin tilapia inhabiting less saline areas. It has historic significance as a former finish line for the Dakar Rally and remains under consideration for UNESCO World Heritage status, highlighting its cultural and environmental importance.
