Lac Retba and the pink lake edge of Dakar

Lac Retba lies north-east of Dakar on the Cap Vert Peninsula, where a shallow basin meets dunes and salt flats. Its pink water and hypersaline character are the main features that define the place.
Lac Retba’s shallow basin beside the Atlantic edge
The lake is a shallow coastal lagoon on Senegal’s Dakar Region side of the peninsula, set just inland from the Atlantic. A narrow dune corridor separates it from the sea, and its basin covers about 3 km², with a maximum depth of 3 m.
3 km² basin and Dakar Region location anchor the lake in a very specific corner of Senegal. The body of water is also tied to the name Lac Rose, the French form that means pink lake.
Salt, algae and the colour on the water
The water’s colour comes from Dunaliella salina, a salt-tolerant microalga associated with the lake’s intense salinity. Reports of salt levels reaching 40% in some areas explain why the lake sits among the most saline waters in the region.
Dunaliella salina and 40% salinity are the two details most closely linked with that colour. The lake is not simply a scenic pool of water; it is a saline environment shaped by evaporation, algae and coastal geography.
A working landscape of salt harvesters
Lac Retba has long been associated with salt extraction, with workers gathering salt from the lakebed and surrounding shallows. That activity gives the shore a practical character: baskets, low banks and pale deposits sit beside the water rather than decorative promenades.
The setting is part wetland, part working ground, and its appearance changes with the level of salt in the water. The result is a landscape that combines water, mineral crusts and dune edges in one compact scene.
Visiting Lac Retba: what travellers from Western Europe should know
- The lake lies north-east of Dakar on the Cap Vert Peninsula. It is reached from the capital by road, with the dunes marking the approach from the Atlantic side.
- The shore is low and open, with salt underfoot in places. The basin is shallow rather than steep, and the edge reads as a broad working margin.
- The official language is French and the currency is the West African CFA franc.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
