The west coast of Corsica is the one I would sail if I had only a week left on the island. The east coast is easier and flatter, the south has Bonifacio and the glamour, but the west is where the mountains fall straight into the sea and the anchorages sit under cliffs of red porphyry that turn the colour of embers at sunset. From Ajaccio to Calvi it is roughly 55 to 60 nautical miles direct, but you would never sail it direct. The pleasure is in the gulfs that bite deep into the coast along the way, and a proper cruise threads through all of them.
I have done this stretch both ways. North to south is easier if the prevailing summer breeze sits in the west or north-west, but I prefer Ajaccio to Calvi because it saves the showpiece, Scandola, for the middle of the trip and finishes you in the easiest harbour on the coast. Here is how I plan it across roughly a week.
Out of the Gulf of Ajaccio
Ajaccio is the obvious starting point. It has two marinas, transport links for crew changes, and the chandlery and provisioning you want before heading up a coast where supplies thin out fast. The Gulf of Ajaccio is a big, deep bay with anchorages of its own, and I like to spend the first night at anchor near the Sanguinaires islands at its mouth rather than pushing straight off. It eases the crew in and the sunset over the islands is the right way to start.
Provisioning matters more on this coast than almost anywhere in France, because the harbours are small and far apart. The Corsica provisioning, water and harbours guide is worth a read before you leave Ajaccio, because once you are north of Sagone you cannot count on filling water or buying much beyond bread and the day's fish.
North to the Gulf of Sagone
The first leg runs north out of the Ajaccio gulf to the Gulf of Sagone, around 15 to 18 miles depending on your line. Sagone is broad and open, with a long beach and a small harbour, and it makes a useful staging point. Cargese, on the northern shore, is the prettier stop, a hill town founded by Greek refugees with two churches facing each other across a ravine and a small harbour below. The anchorage off the town is good in settled weather but exposed to the west, which on this coast is the wind that builds in the afternoon.
That afternoon wind is the single most important thing to understand here. The summer pattern is calm mornings and a sea breeze that fills from the west or south-west by early afternoon, often Force 4 to 5. You sail in the morning and anchor before it builds. The Corsica weather for visitors guide explains the pattern and the warning signs, and ignoring it is how people end up on a lee shore in a swell.
The Gulf of Porto and the Calanche de Piana
North of Cargese the coast becomes spectacular. The Gulf of Porto is a UNESCO World Heritage site, ringed by the red cliffs of the Calanche de Piana, rock formations eroded into towers and arches that glow at dawn and dusk. Anchor off Porto or in one of the coves under the Calanche and you are in one of the great anchorages of the Mediterranean. The water is clear, the holding in sand is good, and the scenery does not let up.
This is roughly the midpoint of the cruise and the place I plan a layday if the forecast allows. There is little ashore beyond the marina village of Porto and the watchtower, but you do not come here for the shops.
Scandola and Girolata
Just north of Porto lies the reason many people sail this coast at all: the Scandola nature reserve, made a UNESCO site in 1975, covering around 900 hectares of land and 1000 hectares of sea. It is a strict reserve, which means no anchoring, no fishing and no landing within its bounds. You may motor or sail through to look, slowly and respectfully, at the red cliffs, the sea caves and the ospreys that nest here in the densest population in the western Mediterranean.
Tucked just south of the reserve is Girolata, a tiny village reachable only by sea or on foot. It sits about 30 nautical miles south of Calvi and has more than 70 organised mooring buoys in a natural shelter, open from April to October. Picking up a buoy here for the night, with the Genoese tower above and no road in or out, is the single best evening of the whole cruise. Book ahead in high season, because the buoys fill.
Across to the Balagne: Calvi and Ile Rousse
From Girolata the final leg runs north to the Balagne, the region around Calvi and Ile Rousse, about 25 to 30 miles. Calvi marina sits beneath its Genoese citadel and is one of the easiest harbours on the coast to enter, working VHF channel 9 with around 500 quayside spaces, of which roughly 150 are kept for visitors. It fills in season, so call ahead or pick up one of the buoys in the bay, which are reasonably priced and put you a short dinghy ride from the town.
Ile Rousse, about 10 miles east of Calvi, makes a worthwhile final detour if you have a spare day. The Calvi, Ile Rousse and the Balagne guide covers both harbours and the anchorages between them, and the Balagne villages in the hills behind are worth a hire car for an afternoon.
Anchoring, holding and the posidonia rules
The west coast is an anchoring cruise more than a marina cruise, and that puts the spotlight on holding and on the seagrass rules that now apply across the French Mediterranean. The good anchorages here are sand, where a modern anchor sets well and holds in the afternoon breeze. The bad ones are posidonia, the protected seagrass that carpets much of the seabed, where an anchor either drags or rips up plants the law increasingly protects. The rule is simple: anchor in clear sand patches, which you can pick out from the colour of the water, and stay off the dark seagrass.
Because the prevailing afternoon wind comes from the west, the anchorages that work are those with shelter from that quarter. Many of the gulf coves open west and become uncomfortable by mid-afternoon, which is the practical reason for the sail-early, anchor-early rhythm. I always set the anchor properly, back down on it under engine, and check my swing against the shore and any neighbours, because a crowded August anchorage with everyone dragging in the evening breeze is a recipe for a bad night. A trip line is worth rigging where the bottom is rocky or foul.
Water, fuel and the spacing of harbours
This is the planning point that catches people who are used to the marina-rich Cote d'Azur. The west coast harbours are small and far apart. Between Ajaccio and Calvi your reliable fuel and water stops are essentially Ajaccio, the small ports at Sagone and Porto, and then Calvi and Ile Rousse. Girolata has buoys but limited services. That means you leave Ajaccio with full water and fuel tanks and you top up at every opportunity rather than waiting until you are low.
For a week-long cruise a couple should manage comfortably with sensible water discipline, but a larger crew in the August heat gets through water fast, and a watermaker earns its keep on this coast in a way it never would in northern France. Plan the trip around the harbours that have services, not around where you would ideally like to stop, and you will never be caught short. Get this wrong and a beautiful cruise turns into an anxious hunt for a water tap.
The verdict
Ajaccio to Calvi is not a long cruise in miles, but it packs more scenery per mile than anywhere else in France I have sailed. The discipline is simple and non-negotiable: sail in the morning, anchor before the afternoon breeze, respect the Scandola reserve, and keep your water tanks topped because the harbours are few. Do that and the west coast gives you red cliffs, clear water, a UNESCO reserve and a finish under the Calvi citadel. If you can only sail one Corsican coast, sail this one.
