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.
Daredevils in red jumpsuits can teeter around the outside edge of Canada's tallest structure next month as Toronto's CN Tower opens a new attraction for thrill-seekers and those wanting to overcome fear. A reporter leans over the edge of the catwalk during the media preview for the "EdgeWalk" on the CN Tower in Toronto, July 27, 2011. Participants are strapped in to a harness that is attached to a guard rail while walking around the catwalk on the structure 356m (1,168ft) off the ground.
