You'll see the best view and best overview of Chicago. At 1,353 feet (412 meters), the Skydeck is the highest observatory in Chicago.
The view is amazing! You can see 40 - 50 miles (65 - 80 kilometers) on a clear day. Imagine seeing Michigan, Indiana, Illinois and Wisconsin, just by walking around the Skydeck. And there's no finer view of Chicago architecture.
