Roughly 20 miles north-east of Dakar is Lac Rose, also known as Lake Retba. 'Rose', meaning pink in French, refers to its colour as a result of a high concentration of minerals. Containing ten times more salt than the ocean, you can swim in this lagoon in a similar fashion as in the Dead Sea - you will float effortlessly! Lac Rose is exploited for its high salt content, with the salt dug up on the southern side, in the area of Niaga-Peul. Senegalese men scrape the bed of the lake, waist-deep in water, to collect the salt which they then dry in the sun before being packed into 50lb bags, ready for the market.
