The Field Museum is absolutely massive and you could easily spend hours exploring! There’s an incredible variety of exhibits covering natural history, science, cultures from around the world, conservation, and evolution, with highlights like SUE the T. rex and the beautiful halls throughout the museum. We especially came for the Pokémon Fossil Museum, which was such a creative way to teach about fossils and paleontology by comparing real specimens with Pokémon! You do need to reserve a timed ticket for the Pokémon exhibit in advance, and despite the limited capacity, the small space still felt pretty crowded with lots of families and kids. Overall, though, the Field Museum is beautiful, fascinating, and easily one of Chicago’s must-visit museums!
