The coast of Posada is made up of three beaches connected to each other. Su Tiriarzu is characterized by a crystal clear sea and surrounded by thick vegetation which adds charm to the landscape. The sand is light and quite fine, mixed with shells. Behind the beach stands the Fava castle, a medieval building with a square tower.
The second beach is Sos Iscraios, whose name means "swamp". It is not particularly large and has light medium-coarse sand with scattered seaweed. The water is blue and the seabed is shallow and sandy. Behind this beach is the Longo pond, home to various species of birds, including the wonderful pink flamingos. This beach is usually less frequented.
The last beach, Orvile, is characterized by light, soft and deep sand. The water is transparent with shades of green and blue, and the seabed slopes gradually. The area behind offers an expanse of dunes, a pleasant pine forest and a vast wetland area protected as a regional reserve, which includes the mouth of the Rio Posada as well as the Longo pond.
Along much of the coast, a path passes through the pine trees, offering wonderful views of the surrounding area, including Posada and the Monte Albo massif.
