Passage du Gois – France
Passage du Gois is a natural pathway with a modest length of just 4.3km. It is located on the Atlantic coast of France in the Vendée region. What makes it dangerous is how this stretch of the D948 road is regularly flooded.
It is flooded twice a day, each time the tide rises! You’ll need to plan when you enter the Passage du Gois – your car could literally be swept away if you go at the wrong time(s) of day.
