The Mont-Saint-Michel bay, listed by UNESCO, extends from Cancale (in Brittany) & Granville (south of Cotentin, in Normandy) 

At a stone's throw from the Breton border, it is on a granite islet where the famous abbey of the same name is located.

A historical monument and jewel of medieval architecture, it welcomes around 2.5 million visitors each year (although it only has a few dozen inhabitants).

The bay is also remarkable for its high tides.

Elles sont l’unes des plus grandes d’Europe continentale, avec un marnage pouvant aller jusqu’à 15 mètres.

A well-known saying compares the speed of the rising tide to “a galloping horse”.

The airspace surrounding the Mont-Saint-Michel ( “R12 – Classified Site”) prohibits the use of drones. To carry out missions close to the site, it is necessary to obtain a specific authorization.
