The National Children's Science Museum is a hands-on science museum for children, a 15-minute walk from Exit 4 of Hyehwa Station. Exhibits that children can touch and operate fill the first and second floors, and the Science Lab on the first floor runs a 20-minute program on a first-come, first-served basis. The 4D experience on the second floor is a separate paid program that lasts 20 minutes. The building has no visitor parking lot, so parking space is scarce on weekends.
