The CN Tower EdgeWalk opens Monday, August 1, 2011 (Civic Holiday) Those courageous or foolish enough to try it will venture out onto 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 storeys) above the ground. As the ad says: “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.” Kids all over the world have been waiting for this.
