This will give you white knuckles..............................................................................................----------------------------------------------------------------------------------------------EdgeWalk is CN Tower’s most thrilling attraction in its 35 year history, and the first of its kind in North America. It is the world’s highest full circle hands-free walk on a 5 ft (1.5 m) wide ledge encircling the top of the Tower’s main pod, 356m/1168ft (116 storeys) above the ground. Visitors walk in groups of six, while attached to an overhead safety rail via a trolley and harness system. Trained EdgeWalk guides will encourage participants to push their personal limits, allowing them to lean back over Toronto with nothing but air and breathtaking views of Lake Ontario beneath them.Designed with the highest international safety and security standards in mind, EdgeWalk runs for 1.5 hours, with the outdoor walk lasting approximately 30 minutes. Tickets cost $175 CAD and include a keepsake video, photos and certificate of achievement. Participants also receive a Total Tower Experience Ticket which includes access to Look Out, Glass Floor, Sky Pod, Movie and Motion Theatre Ride.EdgeWalk will operate May - October in all weather except for electrical storms and high winds. Varying weather conditions will make the EdgeWalk experience different with each visit.You never know what you see:poll not found
