The official Jeju 4·3 Children's Experience Center reservation guide accepts children aged 6–11 for four Monday–Friday sessions: 09:00–10:30, 10:30–12:00, 13:30–15:00 and 15:30–17:00. Each online session accepts up to 30 participants. The center closes on weekends, national public holidays and local holidays. Organized activities are free but require advance booking; the site separately allows free viewing outside program hours. Groups should enquire via 064-723-4327 rather than individual online booking and avoid the 12–1pm lunch break when calling. Check the booking calendar for the intended visit.
