Corsica by boat: anchorages, winds, itineraries

Cruising around Corsica means dealing with four very different coasts: a spectacular west coast exposed to the Libeccio wind, a world-famous far south around Bonifacio and the Lavezzi islands, a flat and sheltered east coast, and a wild Cap Corse. The full circumnavigation is about 220 miles; most crews pick one or two coasts per cruise. Three subjects govern everything else: the wind, the nature reserves and posidonia seagrass.

Four coasts, four kinds of sailing

The west coast, from Calvi to Bonifacio, is the most beautiful and the most demanding: Scandola, Girolata, the gulfs of Porto, Sagone and Valinco. Harbours are scarce (Calvi, Ajaccio, Propriano), the anchorages are superb, but westerly swell rolls in as soon as the wind settles. The far south concentrates Bonifacio and its cliff-cut inlet, the Lavezzi, and Sardinia twelve miles away — with wind almost always accelerated through the strait. The east coast, straight and sandy, offers few stops (Solenzara, Taverna, Campoloro) but often flat water: it is the transit coast. Cap Corse, finally, lines up forty wild miles between Macinaggio and Centuri, to be treated as a genuine headland passage with a solid forecast. Most crews rounding the island do so anticlockwise, keeping the prevailing south-westerly on the beam along the exposed stretch.

The Libeccio runs the show

The Libeccio, a south-westerly, is the dominant wind of the Corsican summer. It quickly builds a rough sea along the whole west coast, strengthens off every headland and turns the Bonifacio Strait into an acceleration zone: expect 10 to 15 knots more than the offshore forecast between Corsica and Sardinia. The Mistral mostly affects the island's north-west. Summer adds thermal breezes on top: calm mornings, 15 to 20 knots in the afternoon, calm again at dusk. The resulting tactics are simple: leave early, be anchored by 2 p.m., and always identify a fallback shelter before setting off. Our glossary covers the marine-weather vocabulary if you need it.

Scandola and Lavezzi: protected sites, strict rules

The Scandola reserve, a World Heritage site, bans anchoring in its core zone and regulates approach and speed: you sail past as a spectator, then pick up a buoy at Girolata. In the Lavezzi, at the heart of the Bonifacio Strait nature reserve, anchoring is organised by zones, buoys are laid in season and fishing is prohibited. These rules change almost every year — new zones, quotas, time windows — so check the regulations in force before the cruise rather than trusting a dated pilot book. Enforcement is very real in July and August, and the fines are designed to sting.

Posidonia: anchor on sand, never on the meadow

Since 2019, French maritime authorities have tightened anchoring rules over posidonia meadows, with an outright ban for larger yachts and mandatory good practice for everyone. In practice:

• look for the pale sand patches, easy to spot in Corsican water;
• check your set with a mask, or check the seagrass maps on dedicated apps;
• use eco-mooring buoys where they are laid (Girolata and Sant'Amanza among others);
• avoid swinging over the meadow: the chain destroys more than the anchor does.

Beyond the possible fine, an anchor set in posidonia holds poorly: seagrass does not grip.

Which coast for which crew

• One week from Ajaccio: the gulf of Ajaccio, Valinco, Bonifacio and the Lavezzi — the most efficient highlights reel.
• One week from Calvi: the Balagne, Scandola, Girolata and the gulf of Porto — the most spectacular.
• Two weeks: the full west coast, returning along the east if the Libeccio digs in.
• Beginner crew or children: the far south in settled weather, short legs and gin-clear water.

Where to start

Get a recent pilot guide to Corsica and cross-check it against the regulations published online — the printed page ages fast here. Book Bonifacio, Calvi and Girolata well ahead for July and August, and keep one flexible night in the plan for weather. Check that your ground tackle is up to the job: 60 metres of chain is no luxury in ten metres of water when the gusts come through. Finally, if Corsica becomes your regular cruising ground, the platform matters: sailing yachts find a perfect playground here, while a fast sports cruiser lets you work around the island in step with the weather windows. Either way, it is the ability to sit comfortably at anchor that makes or breaks the cruise.
