The CN Tower

It may no longer hold the title of “world’s tallest freestanding tower,” but the 553-metre (1,815-foot) CN Tower still stands out in Toronto’s ever-expanding skyline. There are several options for experiencing the tower, the most daring of which, EdgeWalk, involves a tethered walk along the roof of the tower’s main pod. For those seeking a little less adrenaline, the tower offers three observation areas and the revolving 360 Restaurant.
