Tips from the Community
Many visitors run their hand over the chapel's granite wall or briefly place their hand on it. It is said to bring: • Good luck, • Protection on journeys, • or the fulfillment of a wish. However, there is no official historical source to document this custom. It is a local tradition passed down by visitors and tour guides – similar to many pilgrimage sites.

Who was Saint Aubert? According to legend, the Archangel Michael appeared to him in a dream three times in the year 708 and instructed him to build a church on the then Mont-Tombe. Aubert considered the first two apparitions to be dreams and ignored them. On the third occasion, Michael is said to have become impatient and touched him on the forehead with his finger – so forcefully that a hole was created in his skull. This hole, supposedly created by the archangel's finger, is still shown today in the Basilica of Avranches. Only then did Aubert begin the construction of the first sanctuary, from which Mont-Saint-Michel later emerged. The statue therefore shows him as a bishop: • with a mitre on his head, • in bishop's vestments, • with his right arm raised in a gesture of blessing, • with the crozier on his shoulder.

The documentary film "Border Paths – The Customs Officers' Trail" is described on its website as follows: "The historic Customs Officers' Trail begins at the famous pilgrimage site of Mont Saint-Michel and is now one of France's most popular hiking trails. Along its 1,700 kilometers, between Mont Saint-Michel in the north and Saint-Nazaire in the south of the Breton peninsula, hikers can discover impressive landscapes with a rich diversity of flora and fauna. Passing rugged cliffs, expansive dunes, and seemingly endless beaches, hikers become border crossers on a floating border that shifts with the rhythm of the tides." ``` The video about the "Sentier des Douaniers" (duration: 43 minutes / language: German) in the ARD media library can be accessed via the following link =>> https://www.ardmediathek.de/video/grenzwege-der-zoellnerpfad/grenzwege-der-zoellnerpfad/mdr/Y3JpZDovL21kci5kZS9zZW5kdW5nLzI4MjA0MC81MjE2OTktNTAxNzM2

Between Carolles and Saint-Jean-le-Thomas, beaches, cliffs, and the picturesque Lude Valley alternate. From the valley, the Rocher du Sard and the historic Cabane Vauban offer spectacular views of the Bay of Mont Saint-Michel. Part of the route runs along the historic Customs Path, where sentries and customs officers once monitored the coast. The flat sandy beaches and mudflats at low tide invite strolls, and the GR 223 combines nature, history, and coastal panorama for a particularly charming hike.

The Rocher du Sard lies above the Vallée du Lude. This striking granite rock rises about 70 meters above the sea and offers a commanding view of the Bay of Mont Saint-Michel. Local legend says that the rock was a refuge for the Devil during his battle with the Archangel Michael—hence its nickname, Rocher du Diable.
