Free Admission Days are the perfect opportunity for Illinois residents to explore our general admission exhibitions with your family or a group of science-loving friends. Or, use these days to check out special ticketed exhibitions or a 3D movie with a discounted Discovery or All-Access Pass.
Tickets for Free Days are only available to Illinois residents on-site and cannot be reserved in advance. Please ask a Visitor Services staff member for the special offer and show your Illinois proof of residency. You cannot take advantage of Free Days when buying tickets online.
