Bréhat Island and Paimpol by Boat: Tides, Anchorages and Departure Bases

The pink-rock archipelago, the Ferlas channel, the Trieux estuary and Paimpol's wet dock: sailing around Bréhat, and where to rent a boat — Perros-Guirec, Saint-Malo or Roscoff.

A mile off the Arcouest headland, the Bréhat archipelago lines up its pink granite rocks, its channels turned turquoise at high tide and its agapanthus gardens — a car-free island that makes infinitely more sense from the water than from the footpath. But it is also one of northern Brittany's most technical stretches: one of Europe's largest tidal ranges, strong currents, a dense rocky plateau. Here is how to prepare, and where to start from with a rental boat.

Waters that live by the tide

In this corner of the Côtes-d'Armor, the tidal range reaches some ten metres on big springs: whole anchorages dry out, rocks awash appear where you floated two hours earlier, and the currents of the Ferlas — the channel between Bréhat and the mainland — and of the Trieux estuary demand slack-water passages or a fair current. Nothing insurmountable: this is timetable sailing, not improvisation. Our guide on Atlantic tides gives the method (tide tables, coefficient, safety margin under the keel), and the one on buoyage is anything but theoretical here: the Bréhat plateau is a life-size manual of cardinal marks.

What you see from the water

A lap of the archipelago strings together the Paon lighthouse on its pink granite cliff to the north, the Saint-Michel chapel on its knoll, the Birlot tide mill, and the myriad islets — Béniguet, Lavrec, Logodec — that appear or vanish with the hour. The classic anchorages: Port-Clos, where the ferries land, la Chambre to the south-east, sheltered from westerlies, and la Corderie to the west, the archipelago's finest pool on a mid-flood tide. Opposite, the Trieux estuary winds up to Lézardrieux between woods and granite walls — one of Brittany's most beautiful navigable rivers — and Paimpol offers its wet dock in the town centre, entered by lock around high water. The seabed here also hosts maerl beds, the calcareous algae that serve as nurseries for coastal life and whose fragility Breton research has documented (Grall, J. & Hall-Spencer, J. M., Problems facing maerl conservation in Brittany, Aquatic Conservation, 2003, see the study on Google Scholar): anchor on clean sand, never on the pinkish beds.

Where to start from: no base on Bréhat, three serious options

There is no tracked rental fleet on Bréhat itself or in Paimpol — the area is reached from neighbouring bases. The closest is Perros-Guirec, some twenty miles west along the pink granite coast and the Sept-Îles — our guide on renting a boat in Perros-Guirec details this approach, the most beautiful there is by sea. The Sept-Îles, in passing, host metropolitan France's largest seabird colony, gannets and puffins foremost, censused by Breton ornithologists (Cadiou, B. et al., Recensement des oiseaux marins nicheurs de France métropolitaine, see the study on Google Scholar): you sail past without landing. To the east, Saint-Malo opens a longer passage towards Bréhat via Cap Fréhel — our guide on Saint-Malo and the Rance sets up the base, and the one on Cap Fréhel and the bay of Saint-Brieuc describes the route. To the west, finally, Roscoff remains an option for anyone combining with the bay of Morlaix (our guide).

Without renting: the Arcouest ferries

As at the Glénan, there is an alternative for those who don't want the helm: ferries cross from the Arcouest headland in ten minutes, with a commented lap of the island in season. The reasoning of our guide ferry or rental boat applies word for word: the ferry to see, the rental to live the waters at your own pace — provided you accept the discipline of the tides. Boat-Comparator queries Boataround, SamBoat and Click&Boat live across every base in Brittany: compare Perros-Guirec, Saint-Malo and Roscoff for your dates, and watch the tidal coefficient as closely as the weather.
