Île Besnard

Île Besnard is a tidal island off Saint-Coulomb featuring sheer cliffs about 44 meters high and a sandy causeway connecting to Meinga Point. The site forms a natural barrier protecting Rothéneuf harbor and becomes accessible on foot at low tide.

Humans have used this location since the Stone Age, with evidence from the Mesolithic period. In the 17th century, authorities established customs posts here to monitor privateer activities near Saint-Malo.

The island remains tied to fishing traditions that have shaped the region for centuries. Visitors can observe how the coastal community continues to interact with this marine space in their daily activities.

Access to the island depends entirely on tide schedules, which change daily. Visitors should check local information before planning their visit and time their exploration around water levels.

A semaphore tower built in 1862 crowns the summit and is now managed by the Coastal Conservation Authority. This historic structure serves as a vantage point over the bay and forms part of the protected natural site.
