South Sardinia: five coves reachable only by sea
Discover the hidden gems of South Sardinia, jealously guarded by the sea.
There is a Sardinia that road maps cannot tell. It begins where the asphalt ends and the noise of engines gives way to the sound of wind in the sails. For those who choose a sailing charter in South Sardinia, freedom is not just a concept — it is a precise route.
In this article we reveal five jewels of our coast that share one defining characteristic: they are unreachable by land.
Sella Del Diavolo
Located less than an hour’s sail from the harbour, in the heart of the Golfo degli Angeli, its unmistakable silhouette is one of the most iconic features of Cagliari’s skyline.
Its name is tied to an ancient legend: this headland was said to be a corner of paradise so beautiful it drew the envy of Lucifer himself. He challenged the Archangel Michael in battle to claim it, but was defeated and fell into the sea — losing his saddle on impact, which remained forever imprinted on the rock, giving the promontory its unmistakable shape and its name.
Its white limestone cliffs, sculpted by the wind, plunge into a shimmering sea of emerald and turquoise reflections, creating a breathtaking contrast. Seen from the water, the shoreline reveals sea caves and natural arches, while the cliff vegetation — mastic, spurge, juniper — perfumes the air even at a distance. A place where myth, history and nature layer seamlessly over one another.
The sandy bottom makes it an excellent anchorage, well sheltered from the Maestrale.
Isola dei Cavoli
Less than three nautical miles from the coast of Villasimius, Isola dei Cavoli feels like a fragment of the world left behind in time. With its nineteenth-century lighthouse standing watch in silence for over a hundred years, it lies entirely within the Capo Carbonara Marine Protected Area, established in 1998 to safeguard one of the richest and most fragile marine ecosystems in the western Mediterranean.
The surrounding seabed is among the most celebrated for diving: intact Posidonia oceanica meadows, schools of barracuda, large grouper and moray eels inhabiting the rocky crevices. Not far from the island, the wreck of the French merchant vessel Amilcar, sunk in 1964, rests on the seafloor. Nearby lies one of the most moving underwater sites in the Mediterranean: the Madonna del Naufrago — a white Carrara marble sculpture by Pietro Consagra, placed at a depth of around 10 metres in memory of sailors and navigators lost at sea.
The bottom is sandy-rocky with seagrass; anchoring exclusively in sandy patches is strongly recommended to protect the Posidonia. The small coves on the sheltered side of the island offer safe anchorage and waters of a crystalline turquoise.
Cala Zafferano
Along the coast of Teulada, where Sardinia’s southernmost headland reaches toward Africa, Cala Zafferano has spent decades sheltered within the military zone that surrounds it — kept from mass tourism almost by chance, almost by fortune.
The beach is one of the finest in the south of the island: soft, white sand that blushes pink at the waterline, tinted by shell fragments left by the waves. The sea that washes it is of a rare transparency — the shallow reef remains perfectly visible even as the depth increases, making the water shift colour continuously, from intense emerald green to turquoise, through every shade that exists between the two.
The surrounding landscape completes the picture with an almost theatrical precision. To the east, on a high promontory overlooking the bay, rises the tower of Porto Scudo — a sixteenth-century Aragonese watchtower that has stood guard over these waters for centuries. To the west, the beach gradually yields to rocks, where the sea grows darker and more restless. Behind, beyond the dazzling dunes, a dense and lush Mediterranean scrub scents the air with myrtle, mastic and cistus — a green boundary between the sea and the silence of the hinterland.
Pan di Zucchero
Off the coast of Masua, on the Costa Iglesiente, stands one of the most iconic and spectacular landscapes in all of Sardinia: the Pan di Zucchero, a 133-metre limestone sea stack rising from the water like a natural cathedral.
You see it appear from a distance — a white vertical form rising from the flat line of the horizon. When you are close enough to feel its shadow on the water, you realise no photograph had prepared you for its beauty. A giant of limestone that towers vertically, streaked with ochre and pearl grey, sculpted by the wind into forms that seem deliberate. Where the rock meets the water, the sea turns emerald green in the shallows, then turquoise, then deep blue within just a few metres — as if every shade existed only to heighten the white of the rock above. At sunset, the colours here are something else entirely.
Equally striking is the view of Porto Flavia, close by: a mining gallery carved by hand into the rock, its openings hanging thirty metres above the sea on the sheer cliff face.
The seabed is deep but sandy; anchoring is ideal in light winds.
Golfo della Mezzaluna
The Golfo della Mezzaluna opens on the southern side of San Pietro like a forgotten amphitheatre. The rocky walls — dark, volcanic trachyte, fractured by the action of the sea — drop sheer for over twenty metres before touching the water: deep blue at the centre, emerald green near the walls, with caves opening at sea level along what the people of Carloforte call the scogliera del Bue Marino. The only way in is by sea.
You approach slowly, with respect. The caves of the Mezzaluna are explored by tender, SUP or by swimming — silent cavities where the monk seal once lived, now watched over by gulls and peregrine falcons nesting on the highest ledges. The water is deep and crystal clear, that shifting colour that changes with the angle of the sun and can never quite be described — green, blue, turquoise, all at once and none of the three. On the western face, almost invisible among the rock, the ruins of an old military outpost stare out to sea in silence.
The anchorage is suitable only for the most experienced sailors: the gulf is exposed and the seabed rocky, suited to those who know their ground tackle well. The reward, for those who stay, is having all of this entirely to themselves.
