Las Salinas de Torrevieja, the pink lake
A lagoon of 1,400 hectares whose water carries 300 to 350 grams of salt per litre, roughly ten times the sea and in the same range as the Dead Sea. That salt is what turns it pink, and it is a working salt works as well as a protected natural park.
Why the water is pink
The colour is not a trick of the light and it is not mineral. It is alive. Dunaliella salina, a microalga, releases carotene when the water turns hypersaline. Halobacteria, salt-loving microorganisms with purple membranes, deepen the tone as the salt concentrates. Artemia salina, the brine shrimp, eats both, takes on their colour and passes it up the chain to the flamingos that eat it.
Bathing and mud baths are prohibited
The lagoon is a state reserve and a natural park, and bathing in it, including the mud baths it was once known for, is not allowed. Two reasons: the salt works operates automated machinery below the waterline, which is dangerous in a way that is not visible from the bank, and the ecosystem is protected. Under the Valencian natural spaces law a breach carries a fine of 60 to 600 euros.
This surprises people, because older guidebooks and plenty of websites still describe the mud baths as a thing to do here. They are out of date. Come for the colour, the birds and the walk, and use the sea for swimming.
Flamingos, and when the colour is strongest
Flamingos gather here in groups that reach two thousand birds in the breeding season, alongside avocets, ringed plovers and Audouin's gulls. Bring anything that magnifies: the difference between a memorable sighting and a pink smudge is a pair of binoculars. The pink deepens as the water evaporates, so late summer into early autumn is the strongest part of the year, and high, vertical light at midday shows the colour better than the golden hour does. After winter rain the lagoon can dilute to a greyish mauve.
