The official Foresttrip directory for Yumyeongsan National Recreational Forest, 79-53 Yumyeongsan-gil, Seorak-myeon, Gapyeong, lists cypress mood lights for KRW 15,000 and mini trays for KRW 16,000, effective May 27, 2026. Both activities run in the forest activity center from April to November except Tuesdays, 10:00–11:30 and 14:00–16:00. Individuals register on site and groups book ahead. A separate mini wood-table class costs KRW 52,000 and requires advance booking for five or more, so its rules are different. Check day-visitor eligibility and stock on 031-589-5487.
