We had three nights and a borrowed mooring at the Vieux Port, and we wanted to make it feel like a proper cruise rather than a series of day sails. La Rochelle turns out to be close to perfect for that. The two pertuis, the wide tidal channels between Re, Oleron and the mainland, give you sheltered water, real tides to think about, and three or four places worth dropping the hook all within a short hop of each other.
This is how we spent the long weekend, what it cost, and the few numbers you actually need before you slip the lines.
Where you start: the marinas of La Rochelle
La Rochelle is one of the largest yachting harbours on the European Atlantic coast, and Les Minimes alone holds around 4,800 berths, so a visitor pontoon is almost always findable even in July. Call the capitainerie on VHF channel 09 as you approach. Most visitors end up at Les Minimes, a long walk or a short water-bus ride from the old town, but if you can get a night on the Vieux Port pontoons, take it: you wake up under the two medieval towers in the middle of the action.
If you want the background on the town itself, where to provision, where the chandlers are, I wrote a separate La Rochelle visitor guide that goes into the practical side. For this piece I am sticking to the water.
One thing to fix in your head before you leave the pontoon: this is a serious tidal coast, with ranges of around 6 metres on springs. Plan every leg around the tide, not the clock.
Day one: across to Saint-Martin-de-Re
The run from La Rochelle to Saint-Martin-de-Re on the north shore of the Ile de Re is short, roughly 14 nautical miles depending on which channel you take, so there is no rush. We left late morning on the last of the flood and carried it most of the way.
Saint-Martin is the prize. It is a walled town with a circular tidal harbour right in the middle, and the inner basin sits behind a gate that opens for a couple of hours either side of high water. Outside the gate there is a seasonal pontoon along the Grand Mole pier and a handful of waiting buoys about half a mile out if you arrive early. Check your draught against the sill before you commit, because the outer harbour dries.
We locked in, tied up under the ramparts, and spent the afternoon walking the fortifications and eating ice cream like every other crew there. For the wider picture of cruising the island, its other harbours and the bridge clearances, the Ile de Re by boat guide is the one I kept open on my phone.
Day two: the anchorages of the Pertuis
Saturday we ignored harbours entirely. The Pertuis Breton and Pertuis d'Antioche are full of sheltered, sandy-bottomed spots that let you anchor for lunch or for the night depending on the forecast. We pottered along the south coast of Re, swam off the boat, then carried on towards the Ile d'Aix.
Aix is the one I would not skip. It is a low, car-free island guarding the mouth of the Charente, and the anchorage off the village is one of the prettiest on this coast in settled weather. Get the tide right, because the streams run hard through the gap between Aix and the Fort Boyard sandbanks. If you want a longer list of where to drop the hook around here, the roundup of Pertuis Charentais anchorages saved us a lot of chart-squinting.
A word of warning that nobody tells first-timers loudly enough: the holding is good in sand but patchy over weed and shell, and the wind against tide chop in the pertuis can be vicious for such sheltered-looking water. We dragged once, in front of an audience, and reset with more scope and a much redder face.
Day three: Fort Boyard, the Charente and back
On our last full day we ran down towards the mouth of the Charente and looked at Fort Boyard from a respectful distance, then turned for home. If you have more time and the tide, you can carry the flood up the Charente towards Rochefort, a winding river passage that feels a world away from the open coast, but that is a day in itself and we did not have it.
Instead we used the afternoon flood to work back up the Pertuis d'Antioche towards La Rochelle. Coming in, you pick up the leading marks for the harbour entrance and call the marina again on VHF 09. We were tied up at Les Minimes by early evening with enough light left for a last walk into town.
What it cost and what to watch
Berthing on this coast in 2025 sits in the broad range you would expect for the French Atlantic: a 10 to 12 metre boat pays somewhere around 35 to 55 euros a night at a marina like Les Minimes in high season, more for the prime spots in Saint-Martin. Two of our three nights were at anchor, which kept the budget honest. For a wider sense of the running costs of cruising here, the notes on Atlantic coast fuel, water and chandlers are worth a read before you go.
The numbers that mattered to us over the weekend:
- La Rochelle to Saint-Martin-de-Re: about 14 nautical miles
- Tidal range on springs: around 6 metres, so every passage is tide-led
- VHF channel for the marinas: 09
- Saint-Martin inner basin: gated, roughly two hours either side of high water
- Les Minimes berths: around 4,800, so space is rarely the problem
Thinking in tides on the Atlantic coast
If you are arriving from a tideless sea, the Pertuis Charentais is a gentle but real introduction to Atlantic tides. The range here is smaller than Brittany but still around 6 metres on springs, and the streams through the gaps between the islands and the mainland are strong enough to make or break a passage. The whole weekend works better if you carry the flood one way and the ebb the other, rather than fighting the stream because the clock says go.
We made a point of checking the tide table the night before each leg and the coefficient each morning, the same daily number French sailors live by. The crash course on Atlantic tides covers the principles, and once you internalise them the pertuis becomes an easy, forgiving place to learn, with short legs and plenty of bolt-holes if you mistime something.
The one genuine hazard is wind against tide. When a fresh westerly meets a strong ebb pouring out of the pertuis, the sea steepens into a short, nasty chop that looks far worse than the wind alone would suggest. We met it once off the south of Re, reefed early, and were glad we did. None of this is dangerous if you respect it, but it catches out crews who treat the sheltered-looking water as a flat pond.
Eating your way round the pertuis
It would be wrong to write up this coast without mentioning the food, because half the reason to cruise here is what comes out of the water. These pertuis grow some of the best oysters and mussels in France, and the harbour towns sell them cheaply straight from the producers. We ate oysters off the stalls in Saint-Martin, bought a sack of mussels from a quayside seller, and cooked them on board at anchor off Aix with a bottle of cold Charentais white.
If you build a little time into the itinerary for the markets and the quayside sellers, the trip becomes as much a food cruise as a sailing one. The pertuis are shallow, sheltered and warm in summer, which is exactly why the shellfish thrive, and exactly why a long weekend here feels so easy.
Would I do it again
Yes, and I would change almost nothing except to add a fourth night and push down to Oleron. The beauty of basing yourself in La Rochelle is the short legs. Nothing on this itinerary is more than a couple of hours under sail, which means you spend your time swimming, eating oysters and watching the light on the water rather than grinding out miles. For a visiting crew with limited days, that is the whole point.
If a long weekend turns into a proper holiday, the obvious next step is the La Rochelle to Gironde cruise south down the coast, or a hop offshore to the Vendee islands. But for a first taste of the Charente coast, three nights in the pertuis is hard to beat.
