Located on the cliffs of Carolles, the ‘Cabane Vauban’ (Vauban hut), built at the end of the 17th century, offers an impressive overlooking of the Mont-Saint-Michel bay. The Mont can be seen towering above a sea of sands, with the Tombelaine rock just besides it. At low tide, the immense bay reveals its sandbanks as far as the eye can see, like a reverence made to the Mont. With the constant changes in light, a walk along the customs officers’ path with a Cotentin donkey (Equus asinus) provides an instant insight into the wilderness of the bay.
