World's Scariest Ski Slopes

La Chavanette, Avoriaz, France

The Ride: Also known as La Mur Suisse—“The Swiss Wall”—this broad, near-vertical run looks deceptively user-friendly from the bottom. The top, though, is another story—especially if it hasn’t snowed in a week. Here, the outrageously steep pitch (between 50 and 55 degrees) and wind-blasted exposure can quickly turn the terrain to slick ice; a fall here means you may tumble for the next 1,000 feet (unless you’re stopped by a car-size mogul).

Insider Trivia: Skiing La Chavanette actually lets you border-hop (or border-plummet). The run is accessed from Avioraz, in France—but you’ll end up near Les Crosets, in Switzerland.
