Yongyeon is where the freshwater and saltwater meet. The legend goes that an envoy was sent to the pond frequently by the Dragon King. The pond is flanked on both sides by eight rock walls that look like folding screens.
Yongyeon bridge moves up and down easily if someone jumps in the middle of the bridge. Also, it has such a beautiful night view. So, many people come to visit the pond at night for the beautiful night scenery.
