A crescent of sand two kilometres long, whose thin grains with their particular dark amber colour, sometimes reddish, sometimes golden, are mixed with shells, set between the protected marine area of Capo Caccia and the head of the Argentiera. The beautiful and deep bay of Porto Ferro is the northern limit of the Riviera del Corallo, a coastal enclave of Sassari, twenty kilometres from Alghero. Inside it "protects" one of the widest beaches of the impervious coast of Nurra, selected as one of the most beautiful in Sardinia by the Touring Club Italy, and the most 'sustainable' by the FEE (Foundation for Environmental Education), awarded the Blue Flag for 2016-18.
The inlet, where some rocks appear here and there, is bathed by clear waters with emerald green and iridescent blue hues, and is framed at each end by headlands of reddish trachyte punctuated by Mediterranean scrub, backed by a beautiful pine forest. The trees, along with sand dunes covered with sea lilies, separate the beach from the beautiful scenery of Lake Baratz, the only natural lake on the island.
