Its spectacular sand dunes are set between the cliffs of Isola Rossa and Punta Li Canneddi. The beautiful and extensive beach of the Marinedda will strike you for the contrast between the shades of its crystalline waters, the light of its sand and the red granite of the imposing rocks with varied shapes. It is part of the same coastal stretch of the Longa beach, which is part of the picturesque fishing village of Isola Rossa, in the territory of Trinità d'Agultu and Vignola. The light, white sand slopes gently into a shallow seabed, suitable for bathing and children's play, and behind it forms dunes covered with Mediterranean vegetation. It is a popular beach for wave surfers and hosts international specialty competitions every August. One part is equipped with deck chairs and umbrellas and offers various services for water sports and boat rental. It is accessible to the disabled, there are ample hotel parking, bars, restaurants, a surf school and rubber dinghy rental.
