Individuals and families may visit the Children's Museum at Chuncheon National Museum without booking in advance. It opens Tuesday–Sunday, 09:30–17:30, with last entry at 17:00, and closes on Mondays, January 1 and Lunar New Year and Chuseok days. For groups, online reservations are recommended and available Tuesday–Friday for 5–60 people per institution. Changes require cancelling the first reservation and applying again; cancellation is allowed until one day before the visit. A group leader may book only one session per day. Entry may be restricted during crowded periods. Call 033-260-1503 for assistance. A separate space for very young children, 'First Steps at the Museum,' has its own operating rules.
