1. Big Bus Hop-on Hop-Off Sightseeing Tour
If you look for flexibility when it comes to sightseeing, this bus tour is your best bet. Choose between a 24 or 48-hour ticket and alight as you please; stepping on for a relaxing ride around the city, and stepping off when you'd like to get up-close and personal with one of the landmarks or attractions. You'll be passing by Willis Tower, Adler Planetarium, Chicago Water Tower, Magnificent Mile and many more must-see sites – with plenty of conveniently-located stops along the way. The route is a loop, so you won't have to worry about straying too far from the starting point.
Don't miss: A shopping trip at Magnificent Mile or a food pitstop at Navy Pier (or both).
