Sardinia Deep Dive: Wild Waters of the West Med
Stand at the helm approaching Capo Testa from the south on a September afternoon and the scene hits you all at once: terracotta granite boulders tumbling into water so clear you can count the sea-grass blades six metres below, a lighthouse white against a cobalt sky, and the wind already building from the north as if the Bocche di Bonifacio is drawing breath. Sardinia does not ease you in gently. It offers splendour and challenge in equal measure, and sailors who commit to its western Mediterranean waters come back year after year.
Geography and Approach Routes
Sardinia lies roughly 200 nautical miles south-west of the Italian mainland and 170 nautical miles south-east of Barcelona, making it a natural waypoint on any west-to-east Mediterranean passage. The island stretches 270 km from north to south and presents a coastline that ranges from the low dune shores of the Gulf of Oristano on the west to the sheer cliffs of the Golfo di Orosei on the east. Most sailing circuits begin at Olbia in the north-east — well connected by flights and an easy overnight from Elba or Civitavecchia — then work clockwise or anti-clockwise depending on prevailing conditions and crew ambition. The dominant wind regime is the Maestrale, the Sardinian name for the north-westerly Mistral that can arrive with little warning and sustain Force 6 to 7 for days at a time. Arrival and departure windows require careful planning, but once you accept the Maestrale as a given, Sardinia rewards you with some of the finest close-hauled sailing in the Mediterranean.
The Maddalena Archipelago
Seven main islands and a constellation of islets make up the Maddalena Archipelago, a national park that occupies the north-eastern corner of the island. The key anchorages — Cala Francese on Isola Caprera, Cala Corsara on Isola Spargi, and the sheltered bay of Cala Brigantina on La Maddalena itself — fill quickly in July and August, but September opens up breathing room. Cala Corsara deserves particular attention: a narrow inlet flanked by wind-sculpted granite that glows amber at sunset, the anchor dropping in 4 metres of crystal white sand. Depths throughout the archipelago are forgiving, mostly 3 to 12 metres over sand and posidonia, and national park regulations prohibit mooring buoys from private anchors in many zones — carry your own mooring lines. The town of La Maddalena has a marina with around 350 berths and a provisioning market, fuel dock, and chandlery sufficient for a full restock between passages.
Bocche di Bonifacio: Sailing the Strait
The 12-kilometre strait between Sardinia's northern tip and the French island of Corsica is one of the most notorious passages in the western Mediterranean. Wind acceleration through the channel routinely adds 10 to 15 knots above the open-sea reading, and currents can run at 2 to 3 knots in either direction depending on tidal phase and pressure gradient. In settled conditions a fast sloop will cover the crossing in under two hours; in a developing Maestrale the same passage becomes a grey-water, rail-in-water beat demanding full reefing before you leave the anchorage. Check the Météo-France TAF for Figari and the NOAA wind-model overlay together rather than relying on any single source. The Italian Coast Guard maintains a traffic separation scheme in the strait — larger vessels use designated lanes, so sailing yachts crossing should do so at right angles to the lanes as quickly as possible and display the correct lights at night. Clear the cape on the Sardinian side early and you will pick up the Corsican shore in good visibility within the hour.
West Coast: Remote and Rewarding
The western coast of Sardinia is under-sailed compared to the north. Between Alghero and Oristano, the Golfo di Asinara offers wild anchorages in deep blue water beneath limestone plateaus. Alghero itself is a walled Catalan town — Catalunya once controlled this stretch of coast and the local dialect still carries traces of it — with a commercial port and a newer marina on the southern side of the fortified promontory. From Alghero southward, the coastline becomes progressively lonelier. Capo Caccia rears 166 metres above sea level, its caves home to the critically endangered Mediterranean monk seal. Anchorages like Porto Conte and Cala Dragunara offer protection from northerlies and are reachable by a two-hour sail from Alghero. Further south, the Sinis Peninsula and its brackish lagoon sheltering tens of thousands of flamingos signals a dramatic change in character from granite to limestone and dune.
East Coast: Cliffs of Golfo di Orosei
The eastern shoreline between Arbatax and Cala Gonone features some of the most dramatic sea-cliff scenery in the entire Mediterranean. The Golfo di Orosei drops into water over 1000 metres deep just a few miles offshore, and the coastal paths of the Supramonte massif plunge directly into the sea with no road access for more than 40 kilometres. This is strictly open-anchorage territory — there are no marinas between Arbatax and Cala Gonone — and swell from the south-east can make anchorages untenable if a Sirocco builds. In settled conditions, however, coves like Cala Luna, Cala Biriola, and Cala Sisine offer jaw-dropping white-pebble beaches accessible only by sea. Depth-sounders and detailed charts are essential; rock spurs extend well beyond the cliff bases. Cala Luna's lagoon, formed behind a natural stone arch, turns copper-pink at first light.
Seasons, Winds, and Pilotage
May and early June offer warm but unsettled conditions, with the Maestrale arriving unpredictably from the north. Late June through August is the busiest period; anchorages in the Maddalena can hold 80 to 100 yachts on a single night. September is the sailor's favourite month on Sardinia: air temperature around 26°C, sea temperature still at 25°C, Maestrale windows more predictable, anchorages quieter. October brings increasing risk of Tramontane and early Levante gales from the east, but spectacular clarity in the light. The authoritative pilot book for Sardinian waters is Rod Heikell's Italian Waters Pilot, which covers the entire island with detailed approach notes, waypoints, and anchorage sketches. Local VHF channels 68 and 16 are monitored by the Guardia Costiera; in a medical emergency the helicopter response from Olbia or Cagliari is generally under 40 minutes.
Provisioning, Regulations, and Formalities
Sardinia is Italian territory, so EU regulations apply throughout. Non-EU flagged yachts must clear in at Olbia, Cagliari, or Alghero. Anchoring is prohibited in Posidonia oceanica meadows — a regulation enforced with on-the-spot fines — and several zones of the Maddalena National Park require a permit that is obtainable through the park authority's website or via marina offices in La Maddalena. Fuel is available at all major marinas; water is treated as precious on the island and some anchorages have no provisioning access for days at a time. Carry at least 150 litres of water capacity for passages along the east coast.

Plotting a Sardinian circuit begins with understanding the distances: La Maddalena to Olbia is 25 nautical miles, Olbia to Arbatax down the east coast is roughly 115 miles, and Arbatax to Cagliari is another 85 miles.
