Main image

Grand Bé is a small tidal island off the walled city of Saint-Malo in Brittany, France, best known as the burial place of the writer François-René de Chateaubriand.

The island is reached on foot from the city’s Sillon beach at low tide and offers close-up views of Saint-Malo’s ramparts and the surrounding shoreline; the terrain is primarily rocky with low vegetation.

Chateaubriand’s remains were moved to the island in the 19th century, and Grand Bé has since been a familiar historic landmark for visitors to Saint-Malo.

Grand Bé sits immediately offshore from Saint-Malo’s historic center on the English Channel coast and is visited mainly by tourists walking across the tidal flats.

  • Tidal access: Accessible on foot from Saint-Malo at low tide; visitors should consult local tide tables because the crossing is cut by the rising tide.
  • Chateaubriand's tomb: Contains the burial site of the French writer François-René de Chateaubriand, which is the island's principal historic feature.
