The 'Wood Imagination Playground' inside Daejeon Wood Culture Experience Center at Bomunsan is designed for preschool children aged 0–5. The operator's official guide charges KRW 5,000 per child and permits one accompanying adult free of charge; adult supervision is mandatory and only one guardian may enter. The two daily sessions are 10:00–12:00 and 13:00–15:00, each two hours, with a displayed capacity of 20. Only on-site card payment is accepted. Activities may be reserved through Daejeon OK Reservation or requested on arrival, but groups must call before booking. The official October–December 2026 institutional listing offers Tuesday–Friday use from October 1 through December 18, with applications starting September 1 and payment on site. The city's reservation-list view gives December 14 as the deadline, while the site's front-page listing shows December 12; check the active booking form rather than assuming either. The operator separately lists KRW 5,000 per individual child and KRW 3,500 per child for qualifying groups of 20 or more. Do not assume institutional booking availability also applies to individual families. The overall wood center opens 09:00–17:00 in winter and closes on Mondays, January 1 and Lunar New Year/Chuseok holiday periods. Address: 442 Bomunsangongwon-ro, Jung-gu, Daejeon.
