The EdgeWalk at Toronto's CN Tower

The EdgeWalk at Toronto's CN Tower is an adrenaline filled excursion around an open-mesh metal walkway almost a quarter of a mile above the ground. There's no guard rail and no hand holds, just an uninterrupted view of the Toronto skyline and a through-the-mesh view of the ground, 1,168 feet beneath your feet I was among the first in North America to experience the Edge Walk - a hands-free walk on top of the CN Tower, 356 meters high.
