The current visitor guide for the Children's Museum at Gyeongju National Museum lists opening hours of 10:00–17:50, eight sessions each day, and a 50-minute visit per session. Each session is capped at 60 people with first-come online reservations; admission is free. The children's facility is in the basement of the special exhibition building, not just the main gallery. Photography is generally permitted without flash, tripods or commercial use; food is not allowed inside. An older museum notice mentioned 50 people per session, but the current children's museum visitor page lists 60. Check actual reservation capacity and remaining spaces for the day you intend to visit.
