Hanseong Baekje Museum runs Saturday Mongchontoseong family walks from September 19 to November 21, 2026. Only immediate families with a child in primary school or above may attend; preschool children, friends and other relatives are excluded. Two-hour sessions run from 09:30–11:30 or 10:00–12:00. First-come bookings on Seoul's official public reservation site open at 10:00 fifteen days before a session and close at 10:00 one day before; each booking covers two to five family members. The program is free, with cancellation allowed until two days before. Meet outside Hanseong Baekje Hall in the museum's education wing at 71 Wiryeseong-daero, Songpa-gu, Seoul. Arriving over twenty minutes late prevents participation. Bring walking shoes, a hat and water. Rain or a poor-air-quality alert may move the program indoors. Parking fees are not covered.
