The salt works run for several kilometres along the coast road north towards Trapani. The pans are shallow rectangular basins filled with seawater and progressively concentrated through evaporation; in late summer, when the salt is ready, the water turns a strong rose-pink from the halophilic algae that live in it, and the harvested salt is piled in conical white heaps along the embankments.
Several of the old windmills have been restored and one houses a small salt museum that explains the production cycle and the history of the trade. The light here in the hour before sunset is extraordinary — pink water, white salt heaps, dark silhouettes of windmill sails — and the road is lined with pull-offs where people stop to watch.
