Wonang Falls sits in the Donnaeko Valley in Seogwipo, where two streams of water drop into the gorge. The clear blue water reaches depths of 2 to 3 meters and stays cold even in midsummer. After parking at the lot, walk 15 to 20 minutes along the deck path and stairs, and you can borrow a free life jacket by leaving your ID at the bottom. The stairs down to the falls are steep, and the area is crowded during Seongsu.
