The Bay of Mont-Saint-Michel, between sky and sea

Hesitating between the land and the sea, the Bay of Mont-Saint-Michel possesses a wild and fragile beauty that characterises it. On one side is the immense bay marked by the constant flow of the tides and covered with bouchots (mussel beds); on the other, hedged farmlands and moorland sheltered behind the Duchesse Anne sea wall.

Here, the horizon is endless, the gaze barely reaching the contours of Mont-Dol or the spires of Dol-de-Bretagne cathedral. If you love seafood, you absolutely must enjoy a plate of oysters on Cancale harbour, where you can admire a superb view of the bay.


Mont-Saint-Michel bay is an exceptional site registered on the UNESCO World Heritage List. This huge shoreline marked by the biggest tides in Europe reveals itself under a sky that changes according to the time and the seasons, with the proud silhouette of the famous Benedectine abbey behind.



The mussel beds watch over the beauty of this timeless landscape, where the delicate silence transforms your tourist route into a spiritual quest.

From Pointe du Grouin to Couesnon via Cancale or Mont-Dol, take in the unique view of the Bay. Gradually, the route will reveal a succession of magnificent landscapes, to discover on foot or by car, on the road alongside the medieval Duchess Anne sea wall.



Cupped or flat? If you like oysters and fine gastronomy, make a stop on Houle harbour in Cancale. The oyster beds give way to mussel beds. The mussel farms of Hirel, Le Vivier-sur-Mer and Cherrueix pride themselves on being the leading mussel-producing area in France.



Cherrueix and Hirel, situated against the sea wall, have mastered the use of wind power, as shown by the windmills that remain from a time when there were around one hundred in the bay. The quality of the shoreline that stretches as far as the eye can see makes it a very popular spot for sand yachting.

From Saint-Broladre, the polders that extend from the bay are used for farming and salt marshes. Here, the destinies of the sea wall and Chapelle Sainte-Anne, protector of submersible land and a famous pilgrimage centre, are closely linked and dedicated to containing the moods of the sea.

Installed on a natural headland, Roz-sur-Couesnon is rightly considered the balcony of the Bay. Treat yourself to a breathtaking view of the horizon from Cancale to Granville, admiring the polders and Mont-Saint-Michel.



Between Roz-sur-Couesnon and Saint-Georges-de-Grehaigne, between Easter and Christmas, you will come across flocks of sheep grazing on the salt marshes, with the last remaining shepherds in the region. The fresh air is bound to give you an appetite, so take advantage of your visit to discover a speciality : salt marsh lamb.

In the middle of Mont-Saint-Michel bay, Dol-de-Bretagne is one of the oldest towns in Brittany. From the tall towers of the cathedral, it watches over the marshes before the bay.


With a guide, set off to discover the treasures of the bay and absorb the full dimension of these intense landscapes. Your guide will expertly lead you, on foot, through the mudflats and quicksand in this exceptional marine environment. With your binoculars, you might be lucky enough to see the seals that live on our coast.
