The Gois passage is a 4.5-km long tidal causeway which connects at low tide the Noirmoutier island to Beauvoir-sur-Mer on the continent.
Before the Noirmoutier bridge was built in 1971, the Gois passage was the only passable way allowing to reach the island. Today a tourist attraction, the Gois passage is also enjoyed by fishermen on foot. At rising tide, the rescue towers located all along the Passage du Gois are lifesavers for the careless people unable to make it back to the coast in time.
An unusual sports event is held in May, the Foulées du Gois: a running race over the Passage du Gois... at rising tide!
