Lake Retba, Senegal, also known as Lac Rose, reaches up to 40% salinity, making it the second saltiest lake in the world, second only to the Dead Sea.

It is located 35 km northwest of Dakar, the capital of Senegal. It covers only 3 km² and is separated from the Atlantic Ocean only by a narrow strip of dunes.

Its natural beauty and the traditional salt-mining culture surrounding it have earned it a place on UNESCO's Tentative List for future designation as a World Heritage Site.

Lake Retba in Senegal also has a history with sports. It was the finish line for the Dakar Rally before the race moved to South America in 2009.

Color Has an Explanation

Like everything else in life, the color of Lake Retba's water in Senegal also has an explanation. The pink hue is due to a microalga called Dunaliella salina. In extremely salty water, this alga produces a reddish pigment (beta-carotene) to protect itself from intense sunlight.

The higher the salt concentration, the more intense the pink color. However, it can vary between fuchsia, orange, or violet. It all depends on the sunlight and the time of day.

The lake's color is much pinker during the dry season, from November to June. The most vivid color peaks usually occur between January and March.

It's important to emphasize that Lake Retba doesn't remain pink 365 days a year.

It's also important to remember that a flood in 2022 completely washed away the lake's characteristic color and interrupted the salt harvest.

Since then, Lac Rose has never been the same. The colors of the lake change every year and even from one day to the next.

This place is usually visited by:

  • Adventurers who enjoy quad biking or camel rides across the dunes.
  • And, increasingly, environmentally conscious travelers interested in the lake's unique ecosystem.

Lake Retba, Senegal, is best enjoyed in a full day, not as part of a multi-day itinerary or an extended stay.

The lake becomes truly special when you understand the importance of the connection between the natural phenomenon that colors its water and the local economy.

The salt from this lake is harvested by hand, a practice that has been followed for generations. It is also one of Senegal's main sources of table salt and a major export.

The experience of visiting Lake Retba in Senegal has changed since the flooding in 2022. Although the lake itself remains the same, its colors were lost and are only slowly returning.
