The Gulf of Morbihan: Brittany's little sea by boat
Vannes, La Trinité, Quiberon: sailing the Gulf of Morbihan and its little sea of forty islands — currents, tides, license-free boats and sailboats.
'Mor bihan', the little sea: an almost land-locked gulf, some forty islands, currents that spin the water like a river — one of France's most beautiful nautical playgrounds, sailable even when the Atlantic is white-capped offshore.
The waters
Out of Vannes or Port-Blanc, you weave between the Île aux Moines and the Île d'Arz, anchor off Er Lannic and its half-submerged stone circle, run up to Le Bono or the Auray river. Outside, past the Port-Navalo narrows, Quiberon bay opens onto Houat, Hoëdic and Belle-Île — open water, for the manageable days.
Currents and tides: the real subject
The gulf empties and refills through a 1 km channel: on the ebb the current tops 8 knots — faster than some rental boats. The local rule: sail with the tide tables, cross the narrows at slack water, and plan the day with the current rather than against it. Operators brief seriously; listen to them.
License-free, motor or sail
The gulf is license-free paradise (sheltered water, short distances) and small-engine country — €100-250 for the day. Beginner sailboats cruise between the islands, and La Trinité-sur-Mer, France's offshore-racing capital, lines up the finest boats for a sail in the bay.
When to go
May to September, with a preference for June and September (quiet anchorages off the Île aux Moines). Even in mid-summer there is always a sheltered corner — that is the magic of an inland sea. And the price spread between platforms on the gulf's license-free boats is surprisingly wide: compare before booking. The gulf is also a classic stop on campervan routes along the Breton shore — for that leg of the trip, you can compare motorhome rentals along the Atlantic coast.
