Gongju National Museum's Ungjin Baekje Children's Experience Room takes timed online bookings. Slots open at midnight seven days before the visit, with one session per person per day. Individual bookings include 2–5 people including guardians (up to two guardians); group bookings have 10–30 including guardians. Families with four or more children may bring additional unreserved children together with their prebooked group of five, subject to showing a family relationship certificate or eligible multi-child card at the venue.

Enter with the reservation QR code, and children must be accompanied by an adult guardian. If you do not enter within ten minutes after the session starts, the reservation is automatically canceled. Not canceling beforehand and failing to arrive may bring a three-month restriction on new reservations. Cancel personally online before your session starts. Unused slots may reopen on site after the ten-minute threshold, but this is not guaranteed.

The suggested age is six through Grade 2 of elementary school. Interactive displays can have strong sound and light; noise-reducing headphones are available at the desk. Leave strollers outside the room; wheelchairs and walking aids are allowed. Address 34 Gwangwangdanji-gil, Gongju, South Chungcheong Province. Inquiries 041-850-6365 / 6371.
