Cala d'Arena is the most northern beach of the island of Asinara and perhaps its most beautiful, divided in two during the winter by a small brook. to the rear stands a coastal tower dating back to the Sixteenth century. Up to a few decades ago the Loggerhead sea turtle laid its eggs here, and it was also possible to sea some specimens of the monk seal. The beach has brilliant white sand, surrounded by Mediterranean brush and its waters are unbelievably crystal clear. Cala d'Arena is a conservation area mainly due to its extraordinary natural beauty, found in the colours of the sea and in the harsh and evocative rocky areas that alternate with the white sand. A little more to the north of the bay we find the lighthouse of Punta Scorno, that marks the northern extremity of the island of Asinara.
