Take in the view from the sky-high heights of the Willis Tower, the second-tallest building in the United States. From the 103rd floor, look out over 4 states and the Windy City's urban sprawl, and then test your vertigo on a glass balcony to peer down at the streets and skyscrapers of Chicago beneath your feet.

Step into an elevator and be whisked to new heights in just 60 seconds, waiting for the ear-popping sensation as you ascend to the Skydeck at the Willis Tower. Standing 1,353 feet (412 m) above the Midwest metropolis, the Willis Tower’s steel-framed structure was specifically designed to withstand the city's infamous wind—you may even feel a slight sway if visiting during a blustery spell.

From this elevated vantage point, marvel at a panorama that stretches to include 4 neighboring states and the sparkling waters of Lake Michigan. Scan Chicago's iconic skyline, and venture out onto The Ledge—a glass balcony extending from the tower's façade. From this vantage point, it's the skyscrapers that are looking up at you.

Once you've taken in the cloud-level vistas, snag a seat for a showing of Reaching for the Sky, a short movie that traces the Chicago's rise to the top of the architectural world. After the flick, spend some time engaging with the digital floor displays and fascinating trivia games before heading back to ground level.
