Gyeonggi Children's Museum in Yongin runs hands-on exhibits and play areas across its first through third floors. The first floor is for children under 48 months, the second covers the human body and wind, and the third is themed around fairy tales and various countries. Visitors book in advance on the website, then give the reservation name and the last four digits of the phone number at the reception desk to enter. Weekend entry is limited by time slot, but the museum can still be crowded.
