We've seen a lot of scary spots in Norway, but this is the hands-down scariest. It's called Trolltunga, and it's the edge of a cliff. Waaay back in the ice age, glacial water froze a hunk of this mountain and caused it to break off, leaving what locals call "the troll's tongue."

Crazy hikers make the four-hour trek to Trolltunga for the photo opp of a lifetime, on a ledge that hovers about 2,300 feet above the lake below.
