The Costa Rei beach is a long beach that rises in front of the town and extends for kilometers. Easily accessible on foot or by car, it is a pearly white sand beach lapped by placid, surprisingly blue waters. The seabed is low and sandy and you can therefore swim in complete safety. This lovely beach is very popular and is always crowded in the summer months. It is perfect for those who want beautiful sea and greenery in the surroundings, but prefer those easy to reach and equipped with many services to remote and wild beaches. Another beach that is found along the coast of Costa Rei is Piscina Rei, also very famous but generally quieter. Behind it is a small pond. Moving south, you will find the wonderful beaches of Cala Sinzias (7 km) and Cala Pira (10 km). Cala Sinzias is a 2 km long beach of fine golden sand bathed by a transparent sea. The cleanliness of the sea is not surprising – Sardinia is famous for this – but here we arrive at excellence: according to the findings of Legambiente, the waters that bathe Cala Sinzias are among the purest on the island. Cala Pira is a pretty bay bordered by suggestive dunes on which juniper bushes grow here and there. From the sea – wonderfully blue – the gaze runs towards the promontory that surrounds the bay, on top of which for centuries a defense tower built by the Aragonese has stood out.
