Ask a Breton sailor where they would spend a settled week in July and a fair number will point at the same patch of water: the bay of Quiberon and its three islands. It is a near-perfect cruising ground. The legs are short, the islands are different enough from each other to keep you interested, and the bay itself is sheltered behind the Quiberon peninsula from the worst of the Atlantic swell. I have been bringing the boat here for years and I still find anchorages I have not used.
The catch, and there is always a catch in Brittany, is the Teignouse passage and the tides that run through it. Get those right and the bay is a delight. Get them wrong and you spend an afternoon punching a foul stream while the family glares at you.
The lie of the land
Three islands sit out from the mainland marinas. Belle-Ile is the big one, around 18 nautical miles from the Quiberon peninsula, La Trinite-sur-Mer or Le Crouesty. Houat and Hoedic are the smaller two, lying between the mainland and Belle-Ile, so they are roughly six miles closer than the big island. That geography is the key to planning: Houat and Hoedic make easy first hops, Belle-Ile is a proper passage.
Houat is the second largest island in the bay, about 3.3 kilometres long by 1.5 wide, with a permanent population of around a hundred and three main anchorages to choose from. Hoedic lies only about three nautical miles south-east of Houat and is smaller again at roughly 2.5 kilometres in length. Belle-Ile is a different scale entirely, an island with proper towns, a citadel at Le Palais, and a wild Atlantic side you would not anchor on.
Reading the Teignouse passage
To get from the mainland marinas out to the islands most boats use the Teignouse passage, the channel between the Quiberon peninsula and the granite causeway that extends west from Houat. It is buoyed, it is straightforward in fair conditions, and it is genuinely tricky when a sustained wind opposes a strong tidal stream on a big coefficient. Wind against tide in the Teignouse kicks up a short steep sea that is no fun in a small boat.
My rule is simple. I read the tides the night before, and I aim to go through near slack water or with the stream behind me, not into a spring ebb with the breeze on the nose. The passage is predictable. It is only dangerous to crews who do not look at the almanac. For the detailed timing logic, the teignouse passage in quiberon bay notes lay out the gate the way I plan it.
Houat and Hoedic
These two are my favourites and I rate them above Belle-Ile in high summer, because they are quieter and the anchorages are gorgeous. On Houat, the beach at Treac'h ar Goured on the south-east end has fine white sand and clear water, and it is the picture-postcard spot. Beg Salus on the other side is better sheltered from the north-easterly land breeze that often gets up at night in summer, so I tend to move round there for the overnight if the wind is in the north.
Hoedic is tinier and more low-key. Port de l'Argol on the north coast is the main harbour and is better sheltered than Port de la Croix on the south side, so that is where I head. There is almost nothing on the island, which is rather the appeal. You land, you walk, you eat what the one bar is serving, you go back aboard. From Belle-Ile across to Houat is about two hours under sail in a fair wind, so you can island-hop without committing to a long day.

Belle-Ile
Belle-Ile earns its name and its crowds. Le Palais, the main harbour, sits under Vauban's citadel and gets very busy in July and August, so book or plan to raft or take a mooring. Sauzon on the north coast is the prettier harbour and the one I prefer. On the sheltered inner side facing the bay, you will find anchorages off the beaches at Port Fouquet, Port Guen, Port Yorc'h and Les Grands Sables, which are the ones to use when the wind is in the western quarter.
The Atlantic side of Belle-Ile is spectacular and exposed, all cliffs and the famous Aiguilles de Port Coton that Monet painted. You sail past it, you do not anchor against it. For the full island, the belle-ile-en-mer sailing guide goes harbour by harbour.
A week that works
Here is the loop I run with the family, every leg short enough to bail out of:
- Start from a mainland marina, take the Teignouse near slack, and reach across to Houat. Anchor at Treac'h ar Goured or Beg Salus depending on the wind.
- Day two, the short hop to Hoedic, Port de l'Argol for the night.
- Day three, the longer leg to Belle-Ile, Sauzon if there is room, Le Palais if not.
- A day exploring Belle-Ile ashore by hired bike.
- Work back via Houat for a last island night, then the Teignouse home.
That is five or six days with no leg over about three hours, which is exactly what you want with mixed crew aboard. If the weather turns, you simply duck back inside the peninsula and wait.
Weather and shelter in the bay
The great virtue of Quiberon Bay is that the peninsula shelters it from the prevailing westerlies and the Atlantic swell. When it is blowing hard from the west outside, the inner bay stays sailable, and that is where you retreat when a front comes through. The islands themselves are more exposed: Belle-Ile's Atlantic coast takes the full ocean swell, and the anchorages on the seaward sides of Houat and Hoedic become untenable in any westerly weight. The trick is to read the wind direction and pick the lee side of whichever island you are at.
Summer here often brings a thermal sea breeze that fills from the west or north-west in the afternoon and softens at night, which is why the night-time anchorages on the eastern sides of the islands can be calmer than the daytime ones. I move the boat round to the sheltered side for the overnight more often than not. It is a small thing, but it is the difference between a peaceful night and a rolly one.
Provisioning the cruise
There is almost nothing to buy on Houat and Hoedic beyond bread and the day's catch, and Belle-Ile, while it has proper shops at Le Palais, charges island prices. I stock the boat fully at La Trinite or Le Crouesty before I set off, water and diesel included, and treat the islands as places to eat the odd meal ashore rather than to provision. Fresh fish off the boats at Le Palais is the exception, and worth buying. Plan your water, because filling up on the smaller islands is not always straightforward in high season when everyone wants the same tap.
Where the bay connects
The bay of Quiberon sits at the western end of a much larger cruising area. Just to the north-east is the gulf of morbihan by boat, the tidal inland sea that is a whole holiday in itself, and its entrance has its own morbihan entrance timing gate to plan around. To the west, beyond the racing town of La Trinite, the Glenan archipelago and Concarneau open up the rest of south Brittany. Many crews combine the Quiberon islands with a few days in the Gulf, locking the two together into a fortnight.
The takeaway
The bay of Quiberon gives you island cruising at its most forgiving, provided you respect one tidal gate. Plan the Teignouse, keep your legs short, and choose Houat or Hoedic over a packed Le Palais if you want quiet. The bay rewards the boat that reads the coefficients and slows down, and it has done so for me every summer I have come.
