Mont Saint-Michel is a rocky tidal island and a commune in Normandy, France. It is located approximately one kilometre (just over half a mile) off the country's north coast, at the mouth of the Couesnon River near Avranches. The population of the island is 41, as of 2006. The island has been a strategic point holding fortifications since ancient times, and since the 8th century AD it became the seat of the Saint-Michel monastery, from which it draws the name.


The tides in the area change quickly, and have been described by Victor Hugo as "à la vitesse d'un cheval au galop" or "as swiftly as a galloping horse".
The tides can vary greatly, at roughly 14 metres (46 ft) between high and low water marks. Popularly nicknamed "St. Michael in peril of the sea" by medieval pilgrims making their way across the flats, the mount can still pose dangers for visitors who avoid the causeway and attempt the hazardous walk across the sands from the neighbouring coast.
Polderisation and occasional flooding created salt marsh meadows that were found to be ideally suited to grazing sheep. The well-flavoured meat that results from the diet of the sheep in the pré salé (salt meadow) makes agneau de pré-salé (salt meadow lamb), a local specialty that may be found on the menus of restaurants that depend on income from the many visitors to the mount.
