The Gois passage A flooding road, unique in the world

Check the tide times before crossing the Gois passage. In case of average coefficient, beyond 70, you can cross 1 hour and half before and 1 hour and half after low tide.  The Gois passage is a mythical road between Noirmoutier Island and the continent, but also a talented transformist capable of appearing under two very different lights. Whether emerging or hidden, the Gois always has a theatrical flair... a continuous show that delights its spectators.


The Gois Passage is a 4.2 km long, sometimes flooded road connecting Noirmoutier Island to the continent. This fragile link – invisible half the time – is also a fantastic habitat. Whether under the ocean waters or emerging with the tides, the Gois attracts as many birds in search of rest and nourishment as it does shellfish diggers and inquiring minds savouring the beauty of nature. This crossing is an amazing event! Follow the road to Beauvoir-sur-Mer or meet along it to dig for clams, oysters and cockles. Its nine buoys provide refuge to adventurers caught out by the rising waters.

A quick history lesson

The Gois hasn’t always been there. It was created by two currents linking up with large quantities of sand and silt deposited during times of slack water.


Six key dates to remember:

  • 1701: First mention of the Gois on a map.
  • 1766: First crossing of the Gois by Auguste Gauvrit of Barbâtre.
  • 1780: The first buoys are installed along the passage.
  • 1935: Paving of the road begins (completed in 1939).
  • 1942: The Gois is listed as a classified site in the Vendée.
  • 1993: The Tour de France passes over the Gois for the first time.

When can you cross?

If you want to take the Gois Passage, first check the tide tables.

You can travel to or leave Noirmoutier Island via the Gois from 90 minutes before to 90 minutes after low tide. The fog can be very dangerous, particularly for shellfish diggers who can lose all sense of direction and find themselves trapped by the rising tide.

Shellfish on the Gois

The Gois Passage is known for shellfish digging during spring tides.

In fact, you can gather clams, cockles and oysters in the bay around the Gois. Oyster farming also developed here, because the Gois provides access at low tide to oyster beds.
