Of all the incredible Chicago attractions there are to explore, best of all might be the twinkling city skyline. And lucky for you, it doesn't cost a dime to take in its sprawling lineup of world-class architecture—from the Willis Tower and Two Prudential Plaza to Vista Tower. No matter which side of Chicago you call home, you're bound to find some pretty amazing skyline vistas, whether you're peering out from Chicago rooftop bars, commuting on the El or hanging out in a lakeside park. Snap a pic and linger awhile at these appealing vantage points—the views are (mostly) free.
