Midwest Living Review
It's like skydiving, only safer. The new glass ledges on the west side of the Willis Tower opened in July 2009, and people have been flocking to see them since. This unique experience is definitely worth the trip. On a clear day, you can see 4050 miles from the four glass cubes projecting from the 103rd floor. On peak holiday weekends, plan on a 3090-minute wait to get to the ledges. (You will get to hear a lot of cool Chicago trivia while you wait.) There's also a mandatory 10-minute movie about the design and construction of the tower, and a stop on the 99th floor's regular skydeck. When you get to the ledges, someone is bound to say "Don't look down!", but, of course, you will. You'd think this experience wouldn't be much different than leaning with your forehead against the windows on the skydeck, but it is. It is seriously surreal to stand 1,353 feet over the city with seemingly nothing beneath your feet. Admission charged; about $16 for adults, $11 for children.
