Sos Aranzos is found at Sos Aranzos, in the commune of Golfo Aranci. The shore has fine white sand with rocky granite outcrops and wonderful cliffs. The isolated Sos Aranzos beach is one of the most suggestive of the Golfo Aranci coastline, with a view over the Island of Tavolara and Capo Figaro, with its shining extremely fine sand that contrasts with the variegated colours of the water, from green to turquoise blue. It is one of the most popular corners in this area. The little bay set among the cliffs represents a quiet peaceful oasis for the lovers of isolated and secluded gorges. According to an old tradition the name of the beach is linked to the so called “balls” of posidonia formed b y the sea and deposited along the shore.
