This is the tallest observation deck in Chicago and therefore the one you do not want to miss. It affords an amazing view and exciting photo opportunities. You’ll see so much of the city – and even its bordering states – that you may have some questions. Fortunately, interactive computers and exhibits are standing nearby to give you greater detail. Plus, powerful telescopes help you take a closer look. The Willis Tower is still the tallest skyscraper in the United States and a true Chicago icon. Standing on this deck practically makes you part of history! And the view makes it all worthwhile.
