A spectacle that is even more captivating if you observe it from the majestic tower that dominates it from above. The large beach of Bosa Marina is located immediately south of the tourist port and the houses in the coastal district of the medieval town of Bosa, the most important town in the Planargia subregion. This is a wide, golden, sandy shore, a kilometre long and washed by a sea of emerald green and blue waters and a sandy seabed that gently slopes out towards the open sea. Its transparent, clean waters earns it 5 blue sails of the Legambiente (Italian environmentalist association) every year. It is the ideal beach for a totally relaxing day, perfect for families with children, thanks also to services like beach establishments with equipment and boat rentals, places for dining and refreshments, boat trips and scuba diving. You can enjoy numerous beach games and water sports here, like kitesurfing and windsurfing. The lido ends with a trachyte pier connecting the mainland to the Isola Rossa (Red island) alongside the beach, dominated by the Aragonese tower where temporary exhibitions are held in the summer.
