FAQ
Is the range smaller in South Brittany?
Yes: around 5 m at springs, versus over 10 in the north. The Gulf of Morbihan further reduces the range inside but speeds up currents at its narrows.
Can you swim in the Gulf of Morbihan?
Yes, on sheltered beaches, but beware tidal currents at the narrows. Swim preferably at slack water or neaps.
