Cala Niedda (Black Cove) beach is located 5 minutes from trail 102 between Cala Mudanda (or Is Marginis) beach and Cala d'Arcu Silibedda beach, and is characterized by a rocky coastline with the presence, at times, of sand mixed with pebbles, black/gray in color, characteristic of the rocks in the area. Together with the other two coves, it is located on the Capo Sferracavallo coast, little known to visitors and frequented mainly by locals.
