World's Scariest Ski Slopes

Delirium Dive, Sunshine Village, Banff, Canada

The Ride: The topography of this off-piste free-ride zone (it starts with a horizontal rock band that funnels into a tight channel) paired with its ludicrous pitch (much of it around 50 degrees) makes it extremely avalanche-prone. So much so, in fact, that only skiers outfitted with a radio transponder (which, of course, helps rescuers find you in an avalanche) are allowed through a special gate that accesses it.

Insider Trivia: Those hell-bent on conquering the Dive can sign up for Sunshine Village’s “Delirium Sunday” ski-school program.
