The only source of drinking water on the island, this trilevel fall is about 25m (82 ft.) high. When you pass the entrance, follow the trail up around a reservoir, but stop at the Punghyeol, a small hole in the hillside that blows a stream of constant cold air from April to September, especially nice during a summer hike up. Next to the Punghyeol is a pretty cedar forest, which is worth a stop on the way to see the falls.
