21 Best Things to Do in Chicago
"Located in the heart of Chicago's Lincoln Park, this zoo offers free, family-friendly entertainment year-round including the festive Zoolights around the holidays (reservations are required for all visits though). The sprawling grounds are seamlessly woven into the park’s landscape, balancing open, natural spaces and numerous animal exhibits. If you skip the pricey concessions (but maybe spring for a paddle boat ride), Lincoln Park Zoo is a great option to keep all ages occupied while staying on a budget."
