Also known as Lac Retba, this shallow lagoon surrounded by dunes is a popular day-trip destination for dakarois and tourists alike, all coming to enjoy the calm and catch the lake's magic trick – the vibrant and otherworldly pink hues that sometimes colour its waters. The spectacle is caused by the lake's high salt content, which is 10 times that of ocean water. It's a beautiful sight but can only be enjoyed when the light is right – your best chance is in dry season, when the sun is high.
But even if nature refuses to put on her show, a day out here is still enjoyable. You can swim in the lake, buoyed by the salt, or check out the small-scale salt-collecting industry on its shores. And up until the demise of the Dakar Rally, Lac Rose is where the Sahara drivers would arrive and celebrate their victories (or drown their woes).
