"It's safe to say there’s nothing in the world quite like this magical island, topped by a medieval monastery that rises out of the bay like a heavenly apparition. It’s said that, early in the 8th century, a bishop in nearby Avranches was visited by the archangel Michael, who told him to build a church atop an island out to sea. From 966 onward, the dukes of Normandy, supported by French kings, oversaw the development of a major Benedictine abbey on Mont St-Michel. Massive buildings were added throughout the Medieval period, and the abbey became a renowned center of learning, attracting some of the greatest minds in Europe.To access this UNESCO World Heritage site, you must park in an off-site lot and take a shuttle or walk over a footbridge. Recent improvements have made the process much easier, but you should expect crowds in most seasons, as Mont St-Michel is the third most-visited monument in France. After touring the abbey, head to La Mère Poulard restaurant for the signature omelets and butter cookies. There are also several hotels on the island, though most visitors tend to spend the night elsewhere."
