The white salt left at the edge of the water, the pink flamingos in the water while eating the shrimp, among other things, this is why the water of the natural pool is pink. The salty smell all over makes this place a fairytale place. There is often wind, it helps to make the walk more pleasant.
There is a museum here, also worth seeing. The salt museum with a real windmill. They are all quite good. With a few euros you can jump directly to ancient history, even if not so distant, and to the tradition of what it was like to collect salt by hand. By the way, sometimes they still harvest salt by hand, like the famous and rare fleur de sel, rich in minerals and low in sodium, perfect for health.
And last but not least, a beautiful family run restaurant overlooking the salt flats. Outstanding!
