Mandriola with its beach is situated on the north of Sinis and at the base of the promontory of Capo Mannu.
Between the Cape and the beach of Mandriola you can find the cliffs of Sinis, composed by calcareous rocks, that reach the altitude of about twenty metres and descend to the sea.
Behind the coast there is the pond of Sale Porcus, very important because it is populated by flamingoes. The area is a naturalistic oasis realized by LIPU with the collaboration of W.W.F. and Italia Nostra.
