Île du Grand Bé at Low Tide
Twice a day the retreating tide reveals a causeway of wet sand connecting the beach to Grand Bé, the rocky tidal islet where the writer and corsair-romantic François-René de Chateaubriand is buried. The walk across feels like stepping into another, quieter century.
The Crossing and the View
The causeway from Plage de Bon-Secours is passable for roughly two to three hours either side of low tide; check the tide tables posted at the beach entrance or on the Saint-Malo tourist office website before you go. The sand is firm but slippery in places — flat shoes are essential.
From the island's highest point you get a 360-degree view that no rampart walk can match: the full sweep of the walled city to the east, the Fort National on its own islet to the north, and open Atlantic to the west. It is the definitive Saint-Malo photograph.
Chateaubriand's Tomb
At the island's seaward crest sits a simple, unadorned tomb marked only with a cross. Chateaubriand requested burial here so he could hear the sea forever — an instruction that, two centuries on, still feels perfectly kept.
The island is uninhabited and has no facilities, which is exactly why it feels so special. Carry water and leave before the tide turns; visitors have been stranded here and needed coastguard assistance.
