François-René de Chateaubriand was buried on the island in 1848, fulfilling his specific wish to be interred overlooking the sea.
The fort's construction began in 1689 under the orders of King Louis XIV to reinforce Saint-Malo's defenses.
The island is completely cut off from the mainland by the rising tide for approximately six hours of every tidal cycle.
The granite tomb of Chateaubriand is marked only by a simple iron cross.
The island has a sister tidal islet, Petit Bé, located just a few hundred meters further out, which also features a fort.
During the Second World War, the fort was occupied and integrated into the German Atlantic Wall coastal defense system.
The tidal causeway connecting the island to Saint-Malo is made of exposed sand and shingle that changes with the tide.
Grand Bé is a tidal island located off the coast of Saint-Malo, accessible only by foot during low tide. The island is dominated by a 17th-century fort designed by Vauban to protect the port of Saint-Malo. It serves as the final resting place of the French writer François-René de Chateaubriand, who requested to be buried facing the sea. The fort, Fort du Grand Bé, was constructed to defend the city against English naval attacks. Visitors navigate a stone causeway that is submerged by the tide twice daily. The island provides a panoramic vantage point of the Saint-Malo ramparts and the English Channel. It remains an uninhabited natural site managed for its historical significance and coastal ecosystem.

Check the official Saint-Malo tide tables before departing to avoid becoming stranded on the island.
Wear sturdy, non-slip footwear suitable for walking on wet sand, slippery algae-covered rocks, and uneven terrain.
Carry a windbreaker or outer layer, as the island is fully exposed to coastal winds.
Do not attempt to cross the causeway if the tide is beginning to turn, as the water rises rapidly and can be dangerous.
Access is strictly dependent on the tidal schedule and varies daily; the island is often inaccessible during periods of very high tides.
Respect the gravesite of Chateaubriand; maintain quiet and solemn behavior in the tomb area.
