The Children's Museum at the National Maritime Museum in Busan takes online reservations. Walk-in entry is possible only if unused places can be booked on site. Individuals may book from 30 days before the visit through the same day. Children must be accompanied by an adult, and even infants under 36 months need a reservation. For individual visits, one adult is needed for every four children, with a maximum reservation party of nine.
Weekday groups of 10–40 may book in advance, with one adult for every nine children; groups cannot walk in. Five regular sessions operate between 10:00 and 17:00, with a sixth 17:20–18:20 session on weekends and public holidays from April through September. Entry more than 15 minutes after a session starts results in automatic cancellation. QR check-in and wristband collection begin 20 minutes before the session. Inquiries: 051-309-1904.
