I finally visited the famous Yonggwolsan!
The Sky Road stretched out along the smooth cliffs and had an open view of Seomjingang River. It was phenomenal.
The weather was a bummer, but the path was still pretty!
(FYI)
The way to the Yonggwolsan Healing Forest Parking Lot is narrow, so it's hard to control traffic when packed with vehicles. There aren't enough parking spaces, so I recommend you visit on the weekdays!
