As a verifiable entertainment hub, Chicago’s Navy Pier is not to be missed. This 3,000-foot-long (914-meter) playground offers myriad of attractions for children—from a Ferris wheel to a winter ice-skating rink to two children’s museums. Although most of the indoor attractions charge a fee, some offer free admission, including the Smith Museum of Stained Glass Windows. Many people enjoy walking around the pier, which doesn’t cost a thing. Also, from Memorial Day through Labor Day, visitors can watch a free fireworks display every Wednesday and Saturday night.
