About Mont Saint Michel Bay


Mont Saint-Michel Bay is a UNESCO World Heritage Site and is also registered as a Special Protection Zone. This region is an intertidal zone so, when the tide recedes and the bay clears up, it becomes a natural reserve for several birds such as avocet, osprey, and so on. There are over 130 species of birds found in the bay and there are migratory birds like bean goose, wigeon, etc. that make a stop here as well.

It is also home to hundreds of different fish species such as the sea bream, ray, seabass, and so on. As a result, you can also spot seals and dolphins here during the summertime. These sea mammals usually follow the warm currents of the Atlantic Ocean to the coastline of Normandy and can be observed by following the fishing boats.

Although the flora of Mont Saint-Michel bay has greatly suffered due to sand buildup, agricultural products, etc., it still is a major breeding ground. Visitors can find the salicornia plant that grows on salt marshes and is a great food source for the animals grazing here. Mont Saint-Michel Bay is also a popular spot for getting oysters and shellfish and is served all around the world.

What is remarkable about Saint Mont Michel bay is that while the high tide is a beautiful natural phenomenon, low tide offers access to the tidal island. Guests can enjoy a walk on this bay to reach the island and enjoy the gorgeous landscapes surrounding the bay.

Tides of Mont Saint Michel Bay

Mont Saint-Michel Bay, one of the most beautiful bays in the world, has a unique design. Due to the significant tidal movements in this area, high tide at Mont St Michel Bay is a stunning phenomenon to witness, while the low tide leaves the majority of the bay uncovered.

There are two reasons for the bay experiencing the highest tides in Europe — how shallow it is and the Cotentin peninsula forming a natural barrier. The water levels can reach up to 15 meters during high tide. Before road-dykes, Mont Saint-Michel was inaccessible to the pilgrims and the tourists during high tides. The rising of tide is quick and the water advances at a speed of up to 6 km/h that can lead to drowning if you aren’t careful. This is why it is advised to not walk through the Mont Saint-Michel bay without an experienced guide.

The Dykes

The first dyke, Duchess Anne Dyke, was built on the bay in the 11th century to make the island accessible to the pilgrims. In the 19th century, a road-dyke was built and in the 1980s, a new dyke, elevated on pillars, was built to allow the English Channel’s water to flow freely.
