Lake Retba, also called Lac Rose, is a vivid pink lake located north-east of Dakar on Senegal’s Cap Vert Peninsula. Visitors can float easily in its hypersaline waters, take boat rides, or observe traditional salt harvesting along the shores. Notably, the lake’s striking colour, caused by Dunaliella salina algae, is most intense during the dry season, and its salt concentration reaches up to 40%, supporting Senegal’s salt industry.
