Willis Tower

What’s it like to stand 1,353 feet over the sidewalk with just four inches of glass between you and a fall to the ground? If you’re brave enough to find out, step out on one of four glass ledges at SkyDeck Chicago and take a look.

Willis Tower is the tallest building in the United States and offers stunning views of four states from the 103^rd floor. A nine-minute film and some interesting exhibits preclude boarding the elevator, which makes the climb in about one minute.

On a clear day, which unfortunately it wasn’t for our visit, you can see four states: Illinois (obviously), Indiana, Wisconsin and all the way across Lake Michigan into Michigan.

The highlight for many though is the four glass enclosures that extend outside the building and perch you over the ground below.
