Haeundae Arboretum's 'Grow in the Forest' helps children and teenagers explore nature, sharing and conservation. The Busan reservation page lists Thursdays, a programme window of May 14–December 11, 2026 and an online application window of March 3–November 30. This does not mean a session is offered every day within that range: check the dates actually available in the booking calendar. Register as a member, as non-members may have difficulty viewing or cancelling bookings. Registration opening times may be based on the city's server clock. For questions call 051-888-7146.
