Medieval Mont St Michel abbey famously perches on top of a rocky island near the coasts of Normandy and Brittany. This UNESCO World Cultural Heritage-listed site is hugely popular and always busy. The Romanesque-Gothic abbey complex is absolutely worth seeing but most of the other museums on the island are of little real interest. Vic-it is truly worth the $125-136 EUROS to spend the night on Mont St. Michel. It is one of those places that literally takes your breath away from afar but to spend the evening and early morning Mont-Saint-Michel, rocky islet and famous sanctuary in Manche département, Normandy région, France, off the coast of Normandy. It lies 41 miles (66 km) north of Rennes and 32 miles (52 km) east of Saint-Malo. qbt5Lk.
