Chicago’s Skydeck Ledge may be cool for the less adventurous, but Toronto’s Edge Walk was designed just for thrill seeking adrenaline junkies out there.

The Edge Walk at the CN Tower has become Toronto’s most extreme action, allowing brave individuals the opportunity to literally walk on the edge of one of the tallest buildings in the world. Attached to a trolley like harness system railing, groups of 6 people will be guiding around the top of the building, as you lean backwards over the edge. Just how tall is the building you ask? Well the CN Tower is a 116 story building that overlooks the pavement from a heart pounding 1,168 feet.
