Set between the cliffs of Capo Mannu and the coast of su Pallosu, it owes its name to a natural sandstone barrier a few dozen metres from the shore that completely isolates it from the northwesterly “maestrale” waves, creating an authentic natural swimming pool. Sa Mesa Longa, ‘the long table’, one of the pearls of the marine area of the Sinis peninsula, is found in the locality of Putzu Idu, in the territory of San Vero Milis, twenty kilometres away: it is a beautiful, extremely long, varied and multicoloured beach, with ochre yellow soft, fine sand, a pinkish-red colour along the water’s edge made up of pebbles and shells and black rocks that cut the beach in two as it plunges into a sea that, depending on the light, reflects every shade of blue, with its shallow waters and sandy seabed.
