Passage de Gois is a natural passage with a length of 4,3km (2.58-miles), located in the Atlantic coast of France in the Vendée department. This stretch of the D948 road is periodically flooded leading to the island of Noirmoutier in France. It is flooded twice a day by the high tide. This causeway is so unique, that you cannot encounter it anywhere else in the world.
Passage de Gois (also known as Gôa) is located between Île de Noirmoutier and Beauvoir-sur-Mer, in the department of Vendée, and it’s one of the routes that connects the island to the mainland.
The road still remains an adrenaline-pumping journey and is definitely not for the faint of lungs, heart, or legs. A quick glance at the map confirms that this is no hype. This uneven stone paved causeway was first used during the XVI century as the Baie de Bourgneuf gradually silted up. Today the causeway attracts thousands of visitors a year to watch the twice daily uncovering of the 4.3 kilometres of road as it miraculously appears from the sea during the ebbing tide. The drive is definitely worth it. Don’t forget your camera!
The experience of using this road is very impressive. The road's winding design, providing stunning panoramic views, is very curvy and fun for a leisurely ride, so it pays to take it slow. Exercise extreme caution when passing on-coming traffic, over-taking and around corners. Drive with your headlights on at all times as it is easier for oncoming vehicles to see you.
When this paved sandbar that’s flooded twice a day at high tide isn’t submerged, this narrow causeway—flanked by fishing boats and littered with errant clumps of seaweed—is a slippery stretch indeed and especially treacherous on two wheels. This road has been used several times on Tour de France.

The Passage du Gois is an extraordinary location in France and a national monument. The 4,150 meters long causeway is only accessible with the low tide and then only 1 ½ hour before the lowest tide and 1 ½ hour afterwards. Exercise extreme caution when passing on-coming traffic.
