Ses Salines, White sand beach and nude beach in Formentera, Spain.

Ses Salines is a white sand beach with clothing-optional areas on Formentera. The coastal strip extends for several kilometers and is characterized by protected landscape with natural park status.

Ses Salines lies within the Parc Natural de ses Salines d'Eivissa i Formentera, protected by the Balearic government in 2001; the salt pans had already been listed as a wetland of international importance under the Ramsar Convention in 1993. Salt was harvested here for centuries, and the flats and dunes behind the beach remain part of the protected area.

The place is known as a clothing-optional area where visitors practice naturism in a social setting. This tradition reflects an open approach to the body that is common along the Mediterranean coast.

Ses Salines lies at the end of the road that crosses the island from La Savina, and the last stretch runs beside the salt pans. In summer the car park fills early and access by car is limited, so many visitors come by bicycle or on foot along the marked paths. The beach is long and narrow, with the naturist section at the far end; bring water, as there are few facilities along the shore.

Ses Salines takes its name from the salt pans of the Parc Natural de ses Salines, worked since Phoenician and Roman times and still harvested today. The shallow ponds behind the dunes draw flamingos, which feed here during migration, along with other wading birds.
