The Gulf of Orosei: Sardinia's Most Inaccessible Coastline, Accessed

The Gulf of Orosei runs along Sardinia's eastern coast between Dorgali in the north and Baunei in the south — approximately 35 kilometres of coastline backed by the Supramonte limestone massif, which drops directly into the sea in vertical and near-vertical cliffs of up to 400 metres. There are no coastal roads. There are no coastal towns. The beaches — Cala Goloritzé, Cala Mariolu, Cala Biriola, Cala Sisine, Cala Luna — are accessible only by boat from the north or south, or by long trekking routes from the interior that require technical preparation and between three and eight hours of walking. This geography has preserved the gulf as the most ecologically and visually intact stretch of coastline in Italy.

The Beaches of the Gulf of Orosei

Cala Goloritzé is the most protected of the gulf's beaches — in 1993 it was designated a National Natural Monument. Access by boat is the only practical option; the trekking route from the Baunei plateau involves a 6-kilometre path with significant altitude change. The beach itself is approximately 100 metres of white sand and calcareous pebbles at the base of a 143-metre rock monolith (the Aguglia di Goloritzé), one of the most significant sea-climbing routes in Europe. The water colour in the 50-metre-deep cove — a gradation from pale jade in the shallows to deep cobalt at the cove entrance — is the product of limestone filtering through the cliff faces, and the clarity is measurably greater than elsewhere on the eastern coast.

Cala Mariolu, further north, has two beaches — one white sand, one predominantly white pebble — separated by a rock formation. The pebble beach is the broader and draws more boats; the sand beach requires passage through a narrow rock cleft and is typically less occupied. The sea caves at the entrance to the cala are navigable by dinghy or kayak in calm conditions. Cala Biriola, between Goloritzé and Mariolu, is the smallest and least visited of the main beaches — accessible by boat but rarely included in organised excursion routes — and has the character of a private cove without requiring any particular exclusivity.

The Practical Logistics

Private boat hire for the Gulf of Orosei is arranged from the ports of Cala Gonone (north end) or Santa Maria Navarrese (south end). Day charters with a skipper who knows the specific approach lines for each beach are the standard format. The approach to Cala Goloritzé from Cala Gonone takes approximately one hour at normal boat speed; the full circuit of the major beaches in the central gulf requires a departure no later than 8:30 to allow reasonable time at three or four stops. Goloritzé is subject to a daily visitor limit in summer — managed by the Corpo Forestale — and the quota fills rapidly on boats arriving after 10:00.

The sea caves of the northern gulf — Grotta del Bue Marino, historically the Mediterranean monk seal's last mainland refuge, and the Grotta del Fico — are open to boat entry in calm conditions and represent some of the most geologically spectacular marine cave systems in Italy. The Bue Marino caves run 600 metres into the cliff face, with stalactite formations and the characteristic electric-blue light produced by refraction of sunlight through the cave entrance.
