There is a particular smugness to lying at anchor a mile off a marina, watching the masthead lights crammed onto the pontoons, knowing your night costs nothing while theirs costs eighty euros. I have felt it in the lee of Sainte-Marguerite with Cannes glittering across the water, and again behind Ile de Re with La Rochelle's masts in a forest astern. Anchoring is how a cruising budget survives a French summer. But the rules changed, the seagrass is now protected by serious money, and the free lunch comes with conditions. Here is where you can still drop the hook near the busy ports, and what it now costs when it is not free.
The seagrass rules you cannot ignore
Start with the law, because getting this wrong is no longer a slap on the wrist. France has been tightening anchoring rules across the Mediterranean to protect Posidonia oceanica, the slow-growing seagrass meadows that anchors and chain shred in minutes and that take centuries to recover.
The headline regulation targets yachts over 24 metres, which must stay off seagrass and use authorised buoy fields or sandy zones instead. Fines for the big boats reach 150,000 euros, with the threat of being banned from French waters for repeat offenders. Most of us are well under 24 metres, but the principle now shapes where everyone anchors: drop on sand, never on the dark seagrass. The free DONIA app maps the meadows and the restricted zones, and French officials actively recommend it. I check it before every Mediterranean anchorage. Aim the boat at a pale sandy patch, watch the chain go down through clear water, and you are both legal and kind to the seabed.
The Atlantic and Brittany do not have the Posidonia problem, so anchoring there is freer. The constraint up north is tide, not seagrass.
Anchoring off Cannes: the Lerins, free by day
The Lerins islands off Cannes are the classic anchorage with a marina view, and they are the textbook example of how France now manages anchoring near a honeypot port.
Cannes has laid a zone de mouillage et d'equipements legers (ZMEL), an organised mooring zone, to the north of Sainte-Marguerite. It holds 28 boats from 6 to 20 metres inside a 5-hectare buoy field, surrounded by a 43-hectare no-anchor zone protecting the seabed. The clever part for a budget cruiser: it is open from 15 April to 15 October, and by day (0800 to 1800) using the moorings is free and unrestricted. Only the night (1800 to 0800) is paid and needs a reservation. You declare arrival to the Moure Rouge harbour office on VHF channel 9 or by phone. So a lunchtime swim stop off Sainte-Marguerite still costs nothing. An overnight costs the mooring fee, which is still a fraction of a Cannes berth in August.
Around the Hyeres islands: pay by the square metre
Around the Iles d'Hyeres and Port-Cros national park, anchoring is heavily managed and the buoy zones are now the realistic option. The ZMEL pricing here is worth understanding because it sets the pattern for paid moorings on the Med.
At the Port-Cros area zones, the charge runs on occupied surface: roughly 0.58 euros including VAT per square metre of boat (length times beam) for the first two nights, and the rate doubles for each night beyond two. Sailors report paying in the region of 25 euros a night for a typical cruising boat. That structure, cheap for a short stay and punishing for a long one, is deliberate: it keeps the moorings turning over. Treat these zones as one or two-night stops, not a free week.
Some quick numbers to keep your budget honest, from 2025 and 2026:
- Sainte-Marguerite ZMEL: 28 boats, 6 to 20m, free by day, paid 1800 to 0800.
- ZMEL season: open 15 April to 15 October at the managed zones.
- Port-Cros area buoys: about 0.58 euros/m2 including VAT for the first two nights.
- Posidonia fines for over-24m yachts: up to 150,000 euros.
- A Riviera marina berth in August can top 100 euros a night for a modest boat, the reason anchoring pays.
Near La Rochelle and Ile de Re: free, tidal, generous
Cross to the Atlantic and the mood lifts. No seagrass ban, far more genuinely free anchoring, and some of the loveliest spots in France within an hour of a major port.
Around Ile de Re, in settled weather you can anchor outside the port of Le Douhet and off the Saumonards point, and the Fier d'Ars lagoon with its famous Banc du Bucheron sandbank drying at low water is a cruising classic. The catch is the tide. Atlantic spring ranges run 6 to 10 metres, so every anchorage decision starts with the low-water depth, not the depth under you now. Calculate what you will have at LW, allow for swing, and never anchor on the optimism of a rising tide. Get that right and you can sit for free within sight of La Rochelle, the largest marina in Europe with 5,157 berths, while paying none of them.
Brittany and the Glenan: white sand, careful pilotage
For free anchoring at its most beautiful, point the bow at the Glenan archipelago, a ring of islets about 12 miles south of Concarneau enclosing a near-lagoon of white sand and turquoise water. There are no facilities and the pilotage is genuinely tricky among the rocks, but the holding in sand is excellent and the night costs nothing. The Golfe du Morbihan, a 120-square-kilometre near-landlocked sea with over 40 islands, offers good holding in sandy mud, though the tidal streams demand real planning and some anchorages dry completely at low water springs.
This is Brittany's standing trade: free, gorgeous anchoring in exchange for taking the tides seriously. If you have come from the Mediterranean, the ranges will shock you, and I would treat the first few anchorages as a learning exercise rather than a relaxing one.
A practical word on ground tackle, because free anchoring is only free if the anchor holds. The Atlantic and Brittany reward a generous scope and a well-set modern anchor: in sand and sandy mud I let out at least four times the maximum depth I expect at high water, and more in any wind. In the Med, where you are aiming for small sandy patches between seagrass, the discipline is different again, you want to drop precisely and avoid dragging back across a meadow. Either way, a tripline buoy helps in rocky Breton anchorages where a fouled anchor is a real risk, and an anchor alarm earns its keep on a night when the tide turns the boat through 180 degrees. None of this kit is expensive, and it is the difference between a free night's sleep and a 0300 scramble.
Anchoring as part of a wider plan
Anchoring is not a substitute for ever using a port, it is the thing that makes the ports affordable. The pattern that works for most cruising budgets: anchor for free or cheap most nights, take a marina every third or fourth night for water, fuel, showers and laundry, and book that marina sensibly. The mechanics of paying once you do come alongside are covered in the guide to paying in French marinas with cards and cash, and if a permanent base is the goal, the long-stay berth guide for foreigners explains how the annual contracts actually work.
The Mediterranean specifically rewards a clear-eyed plan, because the combination of expensive berths and protected seagrass means freeloading carelessly is no longer an option. My piece on waiting lists and finding a berth on the Med goes into how the two halves, anchoring and berthing, fit together on the Cote d'Azur.
The short version
Drop on sand, never on seagrass, and check DONIA before you let the chain run in the Med. By day the Lerins are still free; by night you pay a modest mooring fee far below a marina berth. On the Atlantic and in Brittany the anchoring is genuinely free and genuinely lovely, and the only tax you pay is doing your tidal homework properly. Get those two disciplines right, seagrass in the south and tides in the north, and France will give you a season of nights at anchor that cost nothing but a careful eye on the depth.
