Daejeon Hanbat Arboretum's overall 2026 interpretation programme began on 16 March with no fixed end date, but its weekday walk-in sessions began on 7 April, while Saturday bookable sessions began on 4 April. Independent garden visits do not require reservations.
Weekday individual walks run Tuesday–Friday at 15:00, meeting outside the ground-floor entrance of the research administration building beside the East Garden tropical greenhouse. Saturday interpretation runs 10:00–11:00 and 14:00–15:00 with mandatory reservations via Daejeon's OK Booking Service, 20 participants per session. Saturday bookings open 90 days before the visit. Applications may initially show as 'pending' until bulk confirmation on the preceding Friday, so a submission does not guarantee a place. Organized groups of 10 or more may book the general programme three months ahead. The general scheme is for ages six and up, with free tours of about 40–60 minutes, depending on the group.
The official 2026 past seasonal pauses differed by programme: Saturday sessions were suspended 4 July–29 August, and weekday individual walks 20 July–14 August. Do not interpret those past summer breaks as a year-round closure. No listed interpretation on Sundays, public holidays or Labour Day; rain can cause cancellations.
