The Passage Du Gois is a peculiar road, located very close to the Gulf of Burnëf on the Atlantic shore of France which connects the Noirmoutier Island to the village Beauvoir sur Mer. It is a road which spans 25 miles and is accessible for only a few hours a day due to high tide which floods it almost completely.
The floods occur twice a day and two watch towers were created to monitor tides and communicate them hours in advance. The towers give accurate information, and announce o the hour and a half before the floods, allowing drivers and pedestrians to plan their transit in advance.
The flood times change every day and it’s seriously dangerous to ignore the warnings during rising tides. Along the road, there are rescue turrets put in place to rescue anyone who may be trapped in order to wait for the low tide, and avoid being submerged in 4 meters of water.
In 1942, the Passage du Gois was declared a French National Historic Monument. In ancient times, before the use of the road, travelers could reach Noirmoutier only by boat. The road was later raised so that animals and people could pass. In 1971, a bridge was built to secure the daily connection with the island.
The road is considered one of the most dangerous roads in the world because of the dense fog which makes it almost impossible to see what lies ahead while driving or walking, and due to the rapid high tides.
