Just west of Merzouga, Dayet Srji is a shallow seasonal salt lake that appears against the improbable backdrop of the Erg Chebbi dunes. It fills after the winter rains and can dry to a cracked, salt-crusted pan by late spring or summer, so what you find depends entirely on the season and the year's rainfall.
When there is water, the lake becomes a magnet for desert birdlife. Greater flamingos are the star attraction, joined by ducks, waders and other migratory species that pause here on their journeys — a startling flash of pink and movement in an otherwise arid landscape. Birdwatchers prize the spot precisely because it is unpredictable and wild, with the dunes rising behind the water for a striking contrast. In dry years the basin is simply an empty white flat, still photogenic in its own stark way.
Because the lake is a genuine 'if the rains came' phenomenon, local knowledge is invaluable. A private driver will know whether there is water and birdlife before you set out, guide you to the best vantage point west of the dunes, and fold the stop into your Merzouga itinerary door-to-door.

Best Time to Visit
Best from late winter into spring (roughly February–April) after the rains, when the lake holds water and birds are present; early morning offers the calmest light and most active birdlife.
