The largest tides in Europe

Because Brittany doesn’t do things by halves, the tides of Saint-Malo and Bay of Mont-Saint-Michel are among the biggest in Europe.
This captivating phenomenon offers breathtaking landscapes that you really must see at least once in your lifetime!

An impressive phenomenon

The tides are particularly renowned in the bays of Saint-Malo and Mont-Saint-Michel, where the difference between high and low tide can be over 14 metres (the equivalent of a four-storey building). On a scale of 20 to 120, the tidal coefficients here regularly reach 110. Victor Hugo described this unique phenomenon by comparing the speed of the tide with that of a galloping horse.

Twice a day, the coast offers up an amazing spectacle where the landscapes are constantly changing.

Seafood collecting at low tide

Low tide is equally as impressive, revealing lunar landscapes. As it ebbs, the water reveals an immense expanse of sand, radically transforming the landscape. This is the ideal time to take a net, a bucket and a spade and walk across the vast uncovered space to collect clams, razor clams, mussels, cockles, oysters, shrimps, etc. There is an abundance of shellfish.

But be careful! The strong currents and the speed at which the water rises require caution. Take advantage of this activity for a breath of sea air and enjoy the beauty of the landscape in front of you.
