The Field Museum is one of the world's great museums of science, environment and culture, a focus of public learning and scholarly research. It's a treasury of more than 20 million objects, from ancient mummies, to endangered plants and animals, to Sue, the largest and most complete T. rex ever found. Above all, The Field Museum is an unforgettable experience for visitors of all ages.
I took the kids on a free day. It was great. There was so much to see without going into any of the the exhibits you had to pay for. We packed a lunch and ate on the east side of museum where there are tables. We parked at the lot just east of the museum for $16. We spent 5 hours and I don't think we saw everything. There are a lot of hands on things for the kids to do too.
