Finistère, the westernmost tip of Brittany, offers 800 km of coastline among the wildest in France. The Iroise Sea, France's first marine reserve, the Raz de Sein and the Fromveur Passage are among the most powerful tidal current zones in Europe (up to 8 knots). The 5 to 7 metre tidal range dramatically transforms the landscape between high and low water.
From the historic ports of Brest and Concarneau to the Molène-Ouessant archipelago, through the beaches of the Bay of Douarnenez, Finistère combines a millennia-old maritime heritage with demanding oceanic conditions. Shore fishing in the abers (Breton rias) and offshore sailing in the Iroise are iconic activities that demand precise knowledge of tide times.
