The Salt Flats of Trapani are a unique coastal area that stretches from Trapani to Marsala. This site consists of active salt pans, small marshes, and streams, with a vast backdune depression dedicated to salt production. The environment is flooded for most of the year and dries up in the summer. The impermeable substrate and unique climatic conditions create a special habitat for rare plants and benthic invertebrates. This area is of great landscape and biological significance, internationally recognized for its ornithological value. Additionally, it hosts endemic and rare insect species.
