A small cove that opens its beauties beyond a thick eucalypt grove, protected by a promontory that offers a spectacular view of the turquoise horizon. The Cala Sinzias beach, 15 kilometres from Villasimius and 7 from Costa Rei, is part of the territory of Castiadas. The cove is a 2-km strip of fine, soft sand, deep and very white, incredibly clear seabed that drops quickly, and crystalline waters with various blue hues, marked by Goletta Verde of Legambiente as one of the cleanest in Sardinia. The beach is dotted with a few rocks, providing the landscape with a variety typical of the eastern coast. Behind it, thick vegetation: junipers, mastics, olive trees, pine trees and eucalypts.

If you love road trips, Cala Sinzias is perfect for you: a parking space equipped for campers and two famous camping sites right in front of the beach. The very wide beach makes it possible to relax in absolute tranquillity and to walk along the shoreline or swim in the deep water, with all services available: parking, beach equipment for rent, bars and restaurants. The beach is accessible to disabled persons, and its sea is so rich that it is a beloved destination of experienced and amateur scuba divers. Beaten by the wind, it is also a popular surfing destination. All 13 kilometres of the Castiadas coast immersed in green are some of the island’s most beautiful areas, with a succession of white-sanded and bright-coloured landscapes. The southern tip of Cala Sinzias is the Cappuccino rock. There begins a little piece of paradise: the Cala Pira beach, with soft sandy dunes and intense Mediterranean scents. To the north, there is Punta San Pietro, with another wide and marvellous beach. Beyond begins the very long coast of Costa Rei, ten kilometres of fine, golden sand that gradually dive into a sea that is the colour of the sky. The territory of Castiadas includes the beaches of Monte Turno, Sant’Elmo, and Santa Giusta, all the way to the Scoglio di Peppino, coastal boundary with Muravera.
