Le Passage de Gois ou Gôa is a natural, periodically flooded passage leading to the island of Noirmoutier in France. It is located between Île de Noirmoutier and Beauvoir-sur-Mer, in the department of Vendée. It is flooded twice a day by the high tide.
Every year, a foot race – the Foulées du Gois– is held across it, starting at the onset of the high tide.
This is similar to Laaningsvejen in Denmark, except you can park along this road what you can't in Denmark.
