Nakgang Mulgil Park is an ecological park below the Andong Dam with a small pond and forest trails. Stone footpaths, fountains and waterside decks sit among metasequoia and fir trees. The park takes 10 to 20 minutes to walk through, and the entrance to Andongru is about 10 minutes on foot. Operations are suspended from May 22, 2026 to December 31, 2027 for a safety reinforcement project.
