National Byeonsan Recreation Forest in Buan lists two free nature activities: 'Stories from Sky, Land and Sea' explores tidal-flat ecology and pollution, while 'Pine Scents and Sea Sounds' introduces local trees and natural sounds.
Both are listed during March–November except Tuesdays, with 10:00–12:00 and 14:00–17:00 time windows. Individuals register onsite; groups book ahead. A separate Byeonsan salt-making activity costs 3,500 won.
Address: 3768 Byeonsan-ro, Byeonsan-myeon, Buan, Jeonbuk; phone 063-581-9977. Check whether tidal and weather conditions affect the day's activity.
