Canada's National Tower announced the imminent opening of its new extreme attraction, EdgeWalk at the CN Tower. The first of its kind in North America, EdgeWalk is the world's highest full circle hands-free walk on a 5 ft (1.5 m) wide ledge encircling the top of the CN Tower's main pod, 356m, (1168 ft , 116 stories) above the ground. This adrenalin-fueled experience will allow thrill seekers to walk the edge of one of the world's greatest man-made wonders beginning summer 2011.
