To the north, the last beach of Castiadas is part of the Costa Rei coastline, confirming all of the area’s most charming characteristics, with a few extra distinctive traits. Santa Giusta consists of a beach about a kilometre long, also known as the beach of Villa Rei, and by a decidedly smaller cove, framed on one side by a small promontory and on the other by a white granitic outcrop known as the Scoglio di Peppino (Peppino’s Rock), with a shape resembling a tortoise. The ‘rock’ marks the border between the coastal territory of Castiadas and that of Muravera and it is one of the main attractions of the Costa Rei. You can lie on its ‘back’ to sunbathe, stop to take some striking photos and practice a few dives.
