This is one of the few parts of the Castellanese shore, mostly consisting of high cliffs of red trachyte, which are formed by a great strip of sand. The Lu Bagnu beach, a neighbourhood of Castelsardo (two and a half kilometres from it), is protected by rocks lined in green: to get to the beach, climb down the steps from the town. The fine sand is the colour of cream, and its clear bottom is dotted with flat rocks that appear here and there, keeping the water warm and pleasant. The beach is suitable for families, thanks to its shallow waters, and is very popular among teenagers. It is perfect for diving aficionados, thanks to its transparent waters brimming with fish, an invitation to hours of adventurous snorkelling. There are several restaurants around, and camping is permitted.
