It is one of the pearls of Posada, on the northeastern coast of Sardinia: a long stretch of sand just a short walk from the village, around a beautiful natural setting
Protected by the rocky outcrop on which the picturesque medieval village of Posada is perched, topped by the scenic Fava Castle, Su Tiriarzu is one of the largest and most beautiful beaches in Baronia, wrapped in an unspoiled natural setting: a wide and long expanse of clear, fine, deep sand dotted with sea lilies; in front it plunges into clear waters of shades ranging from blue to green; behind it it is surrounded by lush vegetation on the shores of the Tondu and Longu ponds and the mouth of the Posada stream; and in the distance stands out majestic and white Montalbo.
The beach is the southernmost part of a long sandy stretch (of four kilometers), which takes on various names in its broad, straight course, and is three kilometers from the town. You will descend the limestone cliffs on which the village climbs, then, having left your car or bike in the parking lot (also suitable for campers), a path will lead you to the beach by crossing a small wooden bridge. The beach, which derives its name from the tiria, a type of broom that grows in the greenery close to the sand, is equipped with all facilities, including beach equipment rental and patinos. Nearby are hotels, camping grounds, bars and eateries. Windswept, it is a destination for surfers and is ideal for snorkeling and spearfishing enthusiasts.
Like su Tiriarzu, Posada’s other beaches are a short distance from the town, all along the low coast formed by the mouth of the Posada stream. To the left of the beach the view is enclosed by a sandy arch surmounted by a low, round hill; to the right you will see the tower of the Posada hamlet of San Giovanni, next to which stretches the beach of San Giovanni. Further south La Caletta and, in the background, Santa Lucia, seaside hamlets of Siniscola. Heading north, you will find the beautiful beaches of Orvili e Iscraios. Behind su Tiriarzu there is first an expanse of dunes and a pine forest, then the lagoon area, alternating with Mediterranean scrub and consisting of river deltas and ponds communicating with each other and with the sea, the habitat of various species of birds, including pink flamingos.
