The National Nakdonggang Institute offers 40-minute permanent-exhibition tours and 20-minute themed tours without an extra guiding fee for visitors. Weekday starts: 10:00 (permanent), 11:00 (theme), 13:00 (permanent), 14:00 (theme), 15:00 (permanent). Weekend starts: 10:30, 11:30, 13:30, 14:30 and 15:30, in the same sequence.
Online reservations are available until the day before visiting. Walk-ups depend on remaining capacity and online reservations take priority. Arrive at the information desk five minutes before the start. On Saturdays, Sundays and holidays, free sensory-table activities are listed at 11:00 and 14:00 and microscope activities at 13:00 and 15:00, with participants recruited by on-site announcements. A free guided tour is not the same as free general admission.
