Corsica sits in an odd spot on the cost map. It is Mediterranean, so people brace for Riviera prices, and then find the island runs cheaper than they feared once they are away from the two or three honeypot harbours. It is also remote enough that a few things, fuel and the odd provisioning run, cost a little more than the mainland.
I cruised the island over a fortnight on a 12-metre boat, two aboard, and kept the receipts. Here is what a Corsica cruise actually costs and how to keep it sensible.
The two-speed island
Corsica's budget splits cleanly. There are the famous harbours, Bonifacio above all, where you pay a premium for the setting, and there is everywhere else, where prices are closer to a normal French marina than to Saint-Tropez. The trick is to spend your money where it buys something unrepeatable and anchor the rest.
Anchoring is the saviour here. The southern gulfs around Porto-Vecchio, the Lavezzi islands, the bays of the west coast: Corsica has anchorages most cruising grounds would envy, and the water is the clearest in France. Every night on the hook is a night you are not paying marina rates, which on the Med start high.
Marina nights: where the money concentrates
Corsican marinas push their rates up 30 to 50 percent in high season and the popular ports fill fast, so a berth is something you book, not assume. Bonifacio, tucked into its limestone fjord, is the priciest and the most spectacular; a 12-metre boat in August pays a clear Mediterranean premium for the privilege of mooring under those cliffs.
Ajaccio's Port Charles Ornano and Calvi sit lower, closer to a standard Med marina than to the fashionable mainland ports. Against the broad Mediterranean band of 50 to 150 euros a night for a 10 to 12 metre boat in season, Corsica mostly lands in the middle, with Bonifacio at the top.
My fortnight ran 6 marina nights and 8 nights at anchor. Six nights at an average of 70 euros, including one expensive Bonifacio night, came to around 420 euros. The eight anchor nights cost nothing. That ratio is the whole budget.
Diesel: the island premium
Here is where remoteness shows. Marina diesel on Corsica runs a little higher than the mainland; Ajaccio quoted 2.31 euros a litre in May 2026, against around 2.12 on the French road network. The fuel berths are also more spread out, so you plan your top-ups rather than assuming a pump in every harbour.
Over a fortnight of coastal hopping and motoring through the calms that the island's lee can throw at you, I burned about 90 litres. At 2.30 euros that is roughly 207 euros. Sail when the thermal breeze fills in, which it reliably does on summer afternoons, and you keep that line down.
Provisioning when the supermarket is a dinghy ride away
Food on Corsica is excellent and mostly priced like the mainland, with the caveat that the smaller harbours have smaller shops and you stock up properly when you reach a town with a real supermarket. A couple's weekly shop still lands in the usual French 75 to 110 euros band, though convenience minimarkets in the resort harbours charge more, so buy the bulk in Ajaccio, Bastia or Propriano.
Corsican charcuterie, cheese and wine are worth the trip on their own. Eat ashore and a plat du jour is around 15 euros, a menu du jour 16 to 28, the same as the mainland away from the fashionable spots. Over the fortnight, provisioning plus a handful of meals ashore put our food at roughly 400 euros. The market-first approach is the same one I lean on in money-saving cruising in France.
The protected-area moorings
One Corsica-specific cost worth knowing: several of the best anchorages sit inside marine reserves where you pick up a paid eco-mooring buoy rather than dropping the hook, to protect the seagrass and the seabed. The Lavezzi and parts of the west coast work this way. Budget a modest mooring fee on those nights rather than a free anchor night, and respect the rules, because the enforcement is real.
A fortnight in Corsica, totalled
Here is a realistic two weeks for two on a 12-metre boat, cruising the island in high summer:
- Berths (8 anchor nights, 6 marina nights at 70 euros): 420 euros
- Eco-mooring fees on reserve nights: 60 euros
- Diesel: 207 euros
- Food (provisions plus meals ashore): 400 euros
- Tax, water, gas, laundry: 90 euros
- Contingency: 150 euros
That lands near 1,327 euros for the fortnight for two, or about 47 euros per person per day. Cheaper than a Riviera fortnight by a clear margin, and the water and the anchorages are arguably better. The contrast with the cost of a Cote d'Azur cruising summer is the reason a lot of cruisers cross to the island and never go back to the mainland coast.
Booking ahead, or paying for it
Corsica in high summer is busy, and the good harbours fill. Bonifacio and the popular gulfs want a reservation, not a hopeful VHF call on the day, and the eco-moorings in the reserves are limited in number. Turn up to Bonifacio in August without a booking and you may find yourself anchored outside in the swell while the inner harbour is full.
The cost angle here is simple: planning saves money. A booked berth at the advertised rate beats a panicked last-minute fix, and arriving early in the day at a reserve mooring beats circling until one comes free or motoring on to the next bay and burning fuel you did not need to. A little forethought keeps the budget where you put it.
Water and the long anchor stints
One practical cost of anchoring out around Corsica is water. The anchorages are glorious and remote, which means no convenient tap, so you carry what you have and top up when you reach a harbour. A boat set up to anchor for days, with decent tankage and ideally a watermaker, cruises the island far more cheaply because it does not need a marina just to fill the tank.
We managed long stretches at anchor between resupply stops, which is what kept our marina nights down to six across the fortnight. Without the tankage to do that, you end up in a harbour every second or third night simply for water and power, and the budget climbs with every forced berth.
Getting there counts too
One honest footnote: Corsica costs more to reach than the mainland coasts, because you have a passage to make from the south of France or Italy before the cruising starts. Build that into the season plan rather than the fortnight budget. Once you are on the island, the cruising itself is among the best value Mediterranean sailing in France.
Timing the island
Corsica's prices and crowds peak in August, like everywhere in the Med. June and September are the cruiser's months: warm water, lighter winds, harbours that are busy but not impossible, and rates that ease off the August top. The reserve moorings are easier to get, the supermarkets in the resort towns are calmer, and the whole island feels less like a competition for space.
If you can shift your fortnight to the shoulders, do. You lose nothing but the peak-season scrum and you gain easier berths, cheaper nights and clearer anchorages. The cruising ground is the same; only the price and the crowd change.
If you are weighing the island against the canals or the Atlantic for a season, the figures in annual running costs of a boat in France put Corsica in context. It is not the cheapest French cruising. For Mediterranean water this clear, at these prices, it is the one I would pick.
