Lac Retba, on Senegal’s Cap Vert Peninsula north-east of Dakar, is a shallow hypersaline lake where pink-tinged water meets pale salt plains and Atlantic dunes in a compact landscape.
A pink lake shaped by salt and light
Lac Retba lies on the Cap Vert Peninsula in western Senegal, north-east of Dakar and separated from the Atlantic Ocean by a corridor of coastal dunes that shields the basin from open surf.north-east of Dakar The lake occupies a low-lying depression and forms a broad shallow bowl of water bordered by sandy banks and pale crusts of salt that accumulate along the shoreline.a depression with a shoreline
The water in Lac Retba is heavily loaded with dissolved salt, reaching concentrations that rival those of the Dead Sea in places and creating an environment where only specialised microorganisms and a few adapted fish can survive.salt content rivals the Dead Sea Under strong sunlight and high salinity, the lake’s surface can take on shades of pink, orange or red as halophilic algae such as Dunaliella salina and salt-loving bacteria produce pigments that colour the water.Dunaliella salina pigments
Salt plains, dunes and working boats
Lac Retba’s shoreline is marked by bright salt flats where crystallised mineral deposits form rough, pale surfaces at the edge of the water, contrasting with the darker dune sand beyond.salt plains form one of Senegal’s landscapes The lake remains shallow across much of its basin, which reinforces the impression of a wide sheet of water spread over a low saucer of sediment framed by modest banks and ridges.
Out on the lake, wooden boats move across the surface to reach areas where salt is harvested, their hulls sitting high on the dense water that increases human buoyancy.so densely laden with salt Around the margins, piles of collected salt rise into low mounds, forming a second layer of pale texture between the coloured water and the dune belt that separates Lac Retba from the Atlantic coast.
Lac Retba in Senegal’s coastal landscape
Lac Retba lies within the Dakar Region, close to the community of Sangalkam, and forms part of a wider zone of coastal dunes, lagoons and beaches on the Atlantic side of Senegal.within the department of Rufisque The lake sits just inland from the ocean, with the dune corridor acting as a sandy barrier between the hypersaline basin and the line of Atlantic surf along the outer shore.
Lac Retba’s combination of coloured water, working salt plains and nearby dunes has drawn attention beyond Senegal, and the site appears on the UNESCO World Heritage Centre’s tentative list under the name “Le Lac Rose” in the mixed category.Le Lac Rose tentative list Proposals describe the lake as a closed coastal lagoon whose salt-rich waters derive largely from interactions between Atlantic seawater and the peninsula’s groundwater, tying the basin to the wider geomorphology of the Cap Vert Peninsula.closed coastal lagoon isolated from the sea

- Lac Retba lies north-east of Dakar on the Cap Vert Peninsula and can be reached by road from the city, with approaches running towards the lake from the coastal highway.
- The terrain around the lake includes uneven salt flats and sand dunes, so walking on the shoreline involves moving over rough, sometimes crusted surfaces and loose dune sand.
- Lac Retba sits close to the Atlantic coast, and viewpoints from the surrounding dunes can combine views over the coloured lake basin with the ocean beyond.
