We have taken our two children sailing in both Brittany and the Mediterranean, at ages when one of them still needed a nap and the other needed feeding every ninety minutes. The two cruising grounds gave us completely different family holidays. If you are trying to choose for your own crew, here is the comparison I wish someone had handed me before our first trip.
The warmth question, settled first
For most families this decides it before anything else. The Med wins on warmth, comfortably. The Cote d'Azur water peaks around 23 degrees, with July, August and September all sitting above 21 degrees, warm enough that children spend the whole afternoon in and out of the sea off the back of the boat. Air temperatures on the coast run hot in summer.
Brittany is cooler in every respect. The sea stays bracing even in August, the air is changeable, and a sunny morning can turn to drizzle by lunch. Children swim, but in shorter bursts and often in wetsuits. If your idea of a family cruise is endless swimming and warm evenings in the cockpit, the Med is the honest answer, and the French Riviera sailing guide coast is built for exactly that.
What Brittany trades for the chill is space and a wilder kind of fun: rock pools, vast tidal beaches at low water, fishing for the pot, and anchorages you might have to yourselves. Different children love different things. Mine, slightly to my surprise, preferred Brittany.
Tides change everything for families
This is the practical heart of it. The Med has almost no tide, so the sea you anchor in at six in the evening is the same depth at midnight. For a family that means no tide tables to fret over, no risk of waking up on the mud, and beaches that stay put. The Gulf of Morbihan by boat is glorious, but it runs serious tidal streams, and you plan around them or you get caught.
Brittany lives by the tide. The range is large, streams run hard, and a sheltered anchorage can dry out under you if you have not checked. This is not a reason to avoid it, but it is more to manage with kids aboard, and a tired skipper distracted by a tidal gate is no fun for anyone. If you come from tideless waters, the Brittany tides for Mediterranean sailors crash course is essential reading before you go.
For sheer ease with young children, the Med's lack of tide is a genuine advantage. For older kids who find tides fascinating, Brittany turns the daily plan into an adventure.
Sailing conditions and stress
A family holiday lives and dies on how stressed the skipper is, so the conditions matter as much as the scenery.
The Med is light-air and tide-free, a recognised beginner ground where currents cause few problems. The catch is the mistral, which can blow hard and pin you in port, and summer thunderstorms that build fast. But on a normal day the sailing is gentle, the hops are short, and you can plan around lunch and naps rather than weather. That predictability is gold with small children.
Brittany asks more. The wind is more reliable but the coast is rocky, the tides demand attention, and weather windows matter. It is rewarding sailing, but it is sailing you have to be present for. The south Brittany cruising guide anchorages of Belle-Ile and the Morbihan are some of the loveliest in France, but they reward a skipper who has done the homework, not one juggling a toddler and a tidal atlas at the same moment.
What it costs
Money runs differently on each coast. The French Mediterranean, especially the Riviera, is expensive for berths: a visitor berth for a 10 to 12 metre boat in high season runs 50 to 150 euros a night, and the headline ports go far higher, with a large yacht paying many hundreds a day in summer. Anchoring is free but increasingly restricted by the posidonia protections.
Brittany and the Atlantic are cheaper for berths, often half the Riviera rate, with more all-tide marinas and a strong culture of anchoring out. For a family on a budget, Brittany generally costs less per night. If you are weighing it up, the Cote d'Azur marina fees reality is sobering, and it is a real reason families on a budget drift north.
Against that, getting to the Med may cost more in flights or delivery miles depending on where you start, and the season is longer there, so you may get more usable holiday for the money.
Things to do with kids ashore
The Med offers the beach-club, ice-cream, warm-evening version of a family holiday, plus famous ports the children will recognise. It is easy, polished and reliably sunny. Landing the dinghy for a swim and a gelato is the daily rhythm, and nobody complains.
Brittany offers a more outdoorsy childhood: crabbing in rock pools, walking out across a kilometre of sand at low tide, oysters straight off the trestles, walled towns like Concarneau seen from the water, and islands that feel like proper expeditions. The food markets are superb, and the provisioning a boat in France markets routine becomes part of the fun. It is less about lounging and more about doing.
Season length
The Med has the longer family season. You can comfortably cruise it from late spring into October, with warm water from July to September. Brittany's family window is tighter, really July and August for swimming, with the shoulder months better for sailing than for sunbathing. If your family holiday is locked to the school summer, both work; if you have flexibility, the Med's shoulder season is a quieter, cheaper sweet spot.
Keeping children safe and happy aboard
The safety picture differs between the two coasts, and it shapes how relaxed you can be. On the Med, with no tide and gentle currents, you can let children swim off the boat in a sheltered anchorage with far less anxiety, lifejackets on, and the water is warm enough that a fall in is a giggle rather than a shock. The flat conditions mean less seasickness too, which on a family holiday is no small thing.
Brittany asks for more vigilance. The tidal streams that make the sailing interesting also mean a child should not be swimming where the current runs, and the cold water turns a fall overboard from a fright into a genuine hazard. None of this rules Brittany out, families cruise it happily every summer, but you parent a little harder. Whichever coast you pick, the basics of sailing with kids in France are worth reading: jackstays, lifejacket rules, and keeping the day short enough that nobody melts down.
The other family truth is that the best day is a short one. Long passages bore small children and frighten tired ones. Both coasts let you keep hops to a couple of hours, the Med because the islands and ports are close, Brittany because the anchorages cluster, but you have to resist the skipper's urge to push on. Plan around naps and lunch, not distance, and both coasts become family-friendly.
Berths, anchoring and the daily rhythm
The daily decision, marina or anchor, plays out differently with kids aboard. On the Med, families often anchor for the swimming and take the occasional berth to reprovision and run the children ashore for ice cream and a playground. The free anchoring is being squeezed by the seagrass protections, so you cannot rely on dropping the hook anywhere, but a good bay with warm water is family heaven. When you do need a berth, book ahead, because August on the Riviera fills up and a family arriving late without a reservation is a stressed family.
In Brittany the rhythm tilts towards drying harbours, all-tide marinas and anchorages you check against the tide. The marina nights are cheaper, which helps the budget, and many Brittany ports have the kind of harbour wall, fishing boats and crabbing that keep children busy for hours. The deciding factor, again, is the parent's appetite for tidal planning versus the wallet's appetite for the Riviera. If you want the full money comparison, the anchoring versus marina costs in France sums apply to families as much as to couples, just multiplied by the number of ice creams.
So which one?
Choose the Mediterranean if you have young children, want warm water and reliable sun, prefer no tides to worry about, and can stomach the berthing costs. It is the lower-stress, higher-comfort family cruise, and it is hard to beat for a first family trip with little ones.
Choose Brittany if your children are a bit older and outdoorsy, you want lower costs and emptier anchorages, you do not mind cooler water and changeable skies, and you (the skipper) are happy to engage with tides. It is the richer, wilder family adventure, and the one mine still talk about.
There is no losing choice here. We have laughed and bickered and made unforgettable memories on both coasts. The honest split is comfort and warmth on the Med, adventure and value in Brittany. Match that to your crew, and pick the holiday they will actually enjoy.
