Lac Rose (Pink Lake): at Lake Retba, everything comes down to salt

At Lac Rose (Pink Lake), do not look for the colour first: look for the salt. It is the salt that tints the water, the salt that makes you float like a cork, the salt that men have been prising from the lake bed for decades, and it was the lack of it that, in 2022, switched the lake off for nearly three years. Once you have understood that, everything makes sense: why the pink is vivid at noon in March and dull on a September morning, why the banks are covered in white pyramids, why the people who live here watch the rain with concern. Here is Lac Rose, told through its main ingredient.

At a glance

Resident or visitor: the same lake, two strategies

Live in Senegal? Your advantage is flexibility. Lac Rose is a morning away from home: you can choose your day. Wait for a fine week in the dry season, a clear sky, a little wind, and leave early to arrive before noon, when the colour comes up. After a very wet hivernage, let a few weeks go by: the lake needs time to become concentrated again. And if you are taking family visiting from abroad, you will be the one with the right calendar in mind. On activities booked with QFS, you get the resident rate: up to 30% off depending on the activity.

Just passing through? You will probably only have one day, and it will not necessarily be the right one for the colour. That does not matter if you know what you are coming to see: a working lake, dunes, harvesters, water that holds you up. Schedule the visit for the middle of the day, keep the late afternoon for the dunes, and do not make the classic mistake of the twenty-minute photo stop. Remember too that the banks are a workplace: ask before photographing anyone.

Salt, the key to everything you will see

A lagoon that closed itself off

Lac Rose has not always been a lake. It was a lagoon open to the ocean, which the sands of the Grande Côte eventually cut off. Severed from the sea, the body of water was fed only by rain and groundwater, and it began to lose more through evaporation than it received. The result: it shrank century after century, until today it covers only about 3 km², with a depth of a few metres at most. And as it shrank, it grew saltier. It was in this water, several times saltier than the ocean, that the lake took on the face we know today.

A living colour, not a dye

The pink comes neither from a mineral nor from pollution, but from a living thing: a micro-alga, Dunaliella salina, one of the few organisms able to thrive in water this salty. To protect itself from the intense sun, it produces a red pigment from the beta-carotene family. The saltier the water and the stronger the sun, the more it produces, and the more the lake turns pink, sometimes mauve in the late afternoon. That is why the colour is not an on-off switch: it varies with the season, the time of day, the wind and the sky. A sunny noon in the dry season is the peak; on an overcast morning in the hivernage, the lake can look greyish-green.

Water that holds you up

The same density of salt explains the most surprising experience of the visit: in Lac Rose, you float effortlessly on your back, just as people describe the Dead Sea. This is not a lake for swimming in; it is a curiosity to enjoy for a few minutes, with a few precautions that we detail below.

Salt as a wage

Finally, salt is an economy. For decades, around 3,000 harvesters have worked on the lake. Standing chest-deep in the water, they break up the crust that forms on the bottom with a pole, bring it up in baskets, load their pirogues, then unload the salt in heaps on the shore, where it dries. Before going into the water, the harvesters coat their bodies in shea butter to protect themselves from water that attacks the skin. The lake’s salt then travels all over the sub-region, much of it used to preserve fish. Depending on the year and the source, production runs into tens of thousands of tonnes: those white pyramids you are photographing are, for thousands of families, the month’s income.

2022: when fresh water switched the lake off

All of this depends on a balance, and the 2022 hivernage broke it. Exceptional rains flooded Dakar’s suburbs; to relieve the neighbourhoods under water, part of the rainwater was drained into the lake. The level rose within a few days, the fresh water diluted the salt, the alga stopped colouring the water and the salt stopped forming. The heaps stored on the banks melted away, the harvest stopped, and with it the pirogues, the sellers and a good share of the visitors. For nearly three years, Lac Rose was no longer pink.

The recovery came from the local people themselves. Harvesters’ associations and residents pooled their money, hired pumps and laid hundreds of metres of pipes to drain the excess water to the sea; the authorities then brought in additional pumping capacity. Little by little, the lake became concentrated again, and in spring 2025 the colour returned. Salt harvesting has resumed since 2025, at the pace at which the salt re-forms. The lesson is simple and applies to your visit: the pink is never a given; it depends on that year’s rain.

A legendary finish line, and a city drawing closer

The lake’s name went round the world long before social media. From its first edition in 1979 until 2007, the Paris–Dakar Rally most often held its finish on these shores, at the end of thousands of kilometres of desert. The 2008 edition was cancelled on the eve of the start, and the race moved to South America in 2009. The sand has kept the memory alive: the Africa Eco Race still celebrates the end of its route here, just before the official finish in Dakar, and in 2021 a round of an electric off-road championship was held on the same dunes. As early as 2005, the state added the lake to its UNESCO World Heritage Tentative List, where it still appears. Today, the danger is no longer just the water: housing estates and new neighbourhoods are spreading towards the lake, and local people are defending a balance that the city could also upset.

Key facts & figures

Getting there & official fees

The lake is reached by road from Dakar, through the north-eastern suburbs, towards Sangalkam and Bambilor. Allow 45 minutes to 1½ hours depending on the time of day: getting out of the city is the only real obstacle, hence the point of leaving early and getting back before the late-afternoon rush. There is no direct, convenient public transport route: the simplest option is still a car with driver, a taxi with a negotiated return fare, or an activity that includes the transfer.

On site, there is no ticket office and no entry fee: the site is freely accessible, and you only pay for the activities you choose. So: no additional official fees. If you have already booked, politely turn down the offers you will get on arrival and head to the meeting point shown on your booking.

What to see

• The lake at midday: this is when salt and sun do their work. Watch the colour change from one area to another, more intense where the water is shallow.
• The harvesters at work: from a pirogue, you can get close to the harvesting areas without getting in anyone’s way. Watch the pole technique, the loading, the return to shore.
• The salt pyramids: on the banks, the heaps drying in the sun tell the story of the season. The higher they are, the healthier the lake.
• A swim: a few minutes lying in the water to feel what “hypersaline” means.
• The ridge of dunes: just a few hundred metres of sand separate the lake from the Atlantic. From the crest, you see the pink water on one side and the Grande Côte’s rollers on the other.
• The nearby villages: Fula (Peul) villages and harvesters’ neighbourhoods, where you can share tea and buy bagged salt and crafts.

Nearby

The lake is part of a cluster of easy outings north-east of Dakar, detailed on our Lac Rose and Dakar Region pages. The Tortoise Village (Village des Tortues), at Noflaye, in the commune of Sangalkam, is a few kilometres away: tortoises in the morning, the lake in the afternoon, it is the simplest family day out from the capital. On the way back, old Rufisque and its trading houses are worth a stop, and the coast at Yène offers quieter beaches the next day. If the dunes have given you a taste for sand as far as the eye can see, the Lompoul desert, further north (see also Lompoul), can be done as a day trip from Lac Rose or with an overnight camp. And for a first visit to the region, combine it with Gorée Island or our Dakar page.

The right time

By season. The dry season, November–June, is the most favourable: little rain, plenty of sun, water that becomes more concentrated. The rainy season, July to October, brings fresh water, and the colour fades, sometimes markedly after heavy downpours. The dunes, the pirogue and the swim remain possible all year round.

By time of day. For the colour, aim for late morning and early afternoon, when the sun is high; a little wind ripples the surface and makes it brighter. For the light and the cooler air, keep the late afternoon for the dunes.

Sunset. Climb onto the ridge of dunes: the sun sets over the Atlantic, the low-angled light turns the lake towards mauve and whitens the heaps of salt. It is the best viewpoint on the site.

By day of the week. On weekdays, the tracks and banks are quieter; at weekends, Dakar residents arrive in numbers from late morning.

Practical tips

• Respect the harvesters: these are people at work, often in harsh conditions. Ask before taking photographs, do not get in the way of loaded pirogues, and do not climb on the heaps of salt.
• Swimming: do not swim with an open wound or just after shaving, as the salt burns. Keep your head out of the water, protect your eyes, and bring fresh water to rinse off when you get out. Do not swim on the ocean side: on the Grande Côte, the currents are powerful.
• Sun: shade is scarce. Hat, sunscreen, sunglasses and plenty of water.
• Clothing: swimwear for the lake, but respectful dress for walking through the villages; closed shoes and a scarf against the sand for motorised outings.
• Cash: small notes for crafts, bagged salt and drinks.
• Environment: take your rubbish away with you, especially plastic bottles, and stay on the marked tracks in the dunes.
