Daeyeon Arboretum's 'Preschool Forest—Rolling Enrollment' is a sensory forest experience for preschool institutions. Busan's official reservation page lists an operating period of 23 March–30 November 2026 and an application period of 20 March at 09:00 through 23 November at 17:00. The program is for institutions serving children aged three to five; it is not advertised as an individual-family booking. Sessions normally take place on weekdays (Monday–Friday), 10:00–12:00 or 13:00–15:00, but times may be adjusted. Each session serves one group of around 20 children. The location is 24 Sinseon-ro 447beon-gil, Nam-gu, Busan. The detailed official description says the program is free. The listed booking method is by telephone on 051-888-6870 or 6872. Some generic instructions on the city page also discuss online booking buttons, so confirm the actual process by phone. Participating institutions must have insurance covering possible forest-activity accidents. Cancellations are normally required seven days before the visit, excluding the visit day. Call the organizer to change group size or times.
