Skydeck Chicago is the thrilling observatory atop the iconic Willis Tower. The highest observation deck in the United States, Skydeck provides breathtaking views of the city, plus up to four states and 50 miles on a clear day. A Skydeck highlight is The Ledge — five glass-floored balconies extending 4.3 feet out from Willis Tower, made up of three layers of half-inch-thick glass laminated into one seamless unit.

After an extensive transformation, Skydeck offers a can’t-miss, one-stop attraction for discovering all that the city of Chicago offers, from an incomparable vantage point. The revamped Skydeck also features a lower-level, museum-like experience that celebrates the unique personality, history, neighborhoods, and sights of Chicago.
