Connecting the Bay of Burnёf with the island of Noirmoutier, the Passage du Gois offers some roadside beauty but is extremely dangerous. The 4.3km long road used since the 16th century disappears under the waters of the Atlantic Ocean twice a day.

Normally, the road is submerged in water 1.3-4m deep, only when the tide recedes, but this period only lasts 1-2 hours. In case people or tourists are walking in the middle of the road when the water rises, the authorities have built rescue towers for people to climb while waiting to be rescued.

Noirmoutier Island is a seaside paradise for nature lovers due to its special microclimate. This beautiful French island is accessible from the mainland via the tidal route Le Passage du Gois. Nearly a third of the island is covered by salt marshes, beautiful sand dunes surround the coastline, and the air is filled with the subtle smell of oak and pine.

The island is full of water activities thanks to 40 kilometers of fine sand beaches. These include sailing, surfing, kitesurfing, jet skiing, and more. The island has three ports – L’ Herbaudière with its lively fishing port and pleasant marina, Port de Morin and its modern marina, and the traditional Port de Noirmoutier en Ile. In addition, the island is also famous for the most expensive La Bonnotte potato specialty in the world. Dubbed the king of potatoes, they are grown on sandy soil fertilized with seaweed.

Later when the authorities built a bridge connecting Noirmoutier Island with the mainland, most people turned to the bridge. However, Passage du Gois is still retained and becomes an interesting tourist destination for visitors. Interestingly, Le Passage du Gois has twice participated in the world-famous Tour de France cycling race. The route was most recently used in 2011 as the starting point of the first leg.
