is millennium park worth the time or a tourist trap?

Millennium Park consistently ranks as one of Chicago's top sights, rather than a secondary attraction, alongside major landmarks like the Art Institute of Chicago, the Field Museum of Natural History, the Museum of Science and Industry, Aqua, and Two Prudential Plaza. If you are planning your trip, the best seasons to visit Chicago are May through June and August through October, when monthly temperatures typically range between 14.8°C and 22.9°C.
