Passage du Gois, France

12 of 13

The Road: Linking the island of Noirmoutier to the mainland town of Beauvoir-sur-Mer in western France, the Passage du Gois is a 2.58-mile paved sandbar that’s flooded twice a day at high tide. When it 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: in 1999, a domino-effect spill took down nearly half of the Tour de France’s peloton.

Insider Tip: Crossing is permitted only during the three-hour window surrounding low tide.
