France Passage du Gois

The Passage du Gois is a natural causeway between Beauvoir-sur-Mer and the island of Noirmoutier. It is flooded twice a day by the high tide. A road runs along the causeway. At low tide, on one side of the road, cars are parked in several rows one behind the other, and people flock with bicycles or walk into the tideland. Everyone has pails or baskets, hammers, small shovels, rakes and other tools to collect the various shells and other seafood.

At Beauvoir sur Mer and on the island there are large displays showing the tide times. About 1½ hours before and after low tide crossing the 4.125 kilometres (2.6 mi) long Passage through the tideland is possible on dry feet.
