EdgeWalk at the CN Tower, has become Toronto’s most extreme attraction. Thrill lovers will walk on the edge of one of the world’s tallest buildings, 356m/1168ft (116 storeys) above the ground. Visitors will 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. Crazy!
