Lake Rosa (locally known as Lake Retba) is located north of the Senegalese Cape Verde peninsula, in the northeast of the African country. At a distance of 35 km from Dakar.
It has an area of 3 km². The adjective pink comes from the color of its waters, which become especially pinkish during the dry season. This is due to an algae called (Dunaliella salina) that makes a red pigment to absorb sunlight.
The high level of salinity allows people to float easily, just like in the Dead Sea.
