Embrace the vertigo—the view from these skywalks, glass bridges, and see-through observation decks are worth it. Check out the slideshow for dizzying images of the Alps, the Grand Canyon, New Zealand, and more.
Chamonix, France
Okay, you may not be stepping into the void, per se, but this
outing does require an extra bit of courage. Visitors enter a glass cube
the size of a phone booth that extends off the edge of Aiguille du Midi
in the French Alps. The elevation: a staggering 12,605 feet. From
there, you can see Mount Blanc and other alpine peaks, the mountain
climbers trying to summit—and a 3,300-foot drop immediately below. Click through to see the rest of the slideshow at the Condé Nast Traveler.
