Cheonjeyeon Falls isn't just breathtaking to look at — it sounds pretty special as well. Find a nice spot to sit, close your eyes and listen to the water tumbling down.
To explore this cascade of water, find your way to Jungmun. There are lots of other things to see and do in this area, such as Sanbangsan Mountain, Jungmun Saekdal Beach, and Jeju Teddy Bear Museum.
