The name derives from the presence of an old concrete jetty, dating back to the first half of the 20th century and now largely submerged and in a state of abandonment.

The beach stretches for about 300 metres against the backdrop of a granite rock promontory covered by sparse Mediterranean shrubs that extends for about 200 metres in a southeasterly direction. A tiny bay called Caletta occidentale (the Western Cove) lies in the centre of this strip of land, and behind it are spectacular dunes of fine, soft sand dotted with centuries-old junipers and other Mediterranean shrubs.

The sand here is fine, with a slightly golden colour that continues, alternating with small granite rocks, through to the shallow seabed, which is suitable even for small children. The water is characteristically clear, going from turquoise to emerald green for many metres off the shoreline. While the beach’s favourable position and sheltered layout make it especially safe and well protected from the winds, it is part of a very delicate ecosystem that formed slowly over millennia.

The entire area behind it is a large natural system of sand, granite rocks and, above all, lagoons that host a dense colony of pink flamingos and other resident and migratory bird species.

Walking on top of the dunes and damaging the ecosystem’s integrity in any way is not allowed. Given its size (a total area of about 10,000 square metres), the site can comfortably accommodate up to 1,200 visitors.
