CN Tower

The CN Tower has defined Toronto’s skyline since 1976 and remains one of the tallest freestanding structures in the world. The LookOut Level and Glass Floor offer dizzying views over the city and Lake Ontario, while the EdgeWalk — a hands-free walk around the outside of the tower’s main pod, 356 metres above the ground — is one of the most extreme attractions in Canada for those who want it. The revolving 360 Restaurant near the top makes for a memorable dinner with the city slowly turning beneath you. Best visited at sunset for photos, or after dark when the tower’s LED lighting display comes alive over the skyline.
