5Mont St. Michel, France

At low-tide, Mont St Michel is just another of the many picturesque communes scattered around northwest France. However, at high-tide the commune becomes an island in a magical transformation that will have you looking around for the island’s fairy godmother.

These high tides occur when the sun, moon and earth align. When this happens the gravitational pull from the sun and moon attracts the water towards it causing the sea level to rise and the tide to come in. The commune’s geographical location also plays a key role in the tidal phenomenon. As the tide comes in from the Atlantic Ocean, it hits the Cotentin coastline like a wall, causing the tidal water to break before flowing into the bay of Mont St Michel.
