Ride a tour boat along the shore and learn all about the architecture of Chicago's skyline. Head over to Navy Pier and watch the fireworks, ride the ferris wheel or see an IMAX movie. After that, shop the Magnificent Mile along Michigan Avenue. Check out Macy's, Bloomingdales and Saks Fifth Avenue.
If it is museums you are interested in, The Field Museum is home to over 20 millions specimens and houses Sue, the largest T-Rex around. After that, head over to the Art Institute of Chicago.
Known for its shorelines, parks and outdoor walking trails, there are plenty of outdoor activities to do while visiting Chicago.

Wander through the park looking at the sculptures while enjoying one of the many outdoor concerts that are held there.
So, plan a trip to Chicago, ride the L-train, go up in the Willis Tower, or catch a White Sox game. With so much to do you will not leave unsatisfied.
