Wonju History Museum publishes free admission and visiting hours of 09:00–18:00. Listed closures include Mondays, January 1, Seollal, Chuseok and the day after a public holiday.
For museum groups of 20 or more, a booking must be made at least one week before the visit. Check the official reservation calendar for available sessions. Student groups must be accompanied by a supervising teacher. Contact the museum if normal booking is difficult.
The museum's different official guidance pages give inconsistent last-entry times, so this guide deliberately does not assert a fixed final entry cutoff. Confirm directly for late afternoon visits.
The museum is listed at 134 Bongsan-ro, Wonju-si, Gangwon. Individual travelers should still check day-specific opening notices and any current program limits.
