Riserva naturale integrale Saline di Trapani e Paceco

Besides Mediterranean flora and fauna, there is a saline work museum in an old salt mill.

The halophyte flora which is adaptable to the salt marshes and the soils with high salt concentrations is represented by some of the rarest plants of Sicily, like the sea marigold (Calendula maritima), Limoniastrum monopetalum, Cynomorium coccineum or Limonium densiflorum.

Rare animals are the osprey (Pandion haliaetus), the peregrine falcon (Falco peregrinus), the common painted frog (Discoglossus pictus), as well as the insect species Bucherillo littoralis, Stenoniscus carinatus, Pterolepis elymica, Cicindela circumdata imperialis, Cicindela littorea goudati, Teia dubia and Aphanius fasciatus.

The salt works are an important stopover for many European migratory birds before they fly across the Strait of Sicily to Africa.

Nearby is the "Salina Culcasi", with Torre di Nubia ( 37°58′54″N 12°29′41″E / 37.98167°N 12.49472°E / 37.98167; 12.49472 ), part of the ancient Torri costiere della Sicilia system to prevent the theft of salt by Barbary pirates from Maghreb.
