Halla-San National Park in Jeju Island contains Halla-San or Halla Mountain, one of Korea’s three notable mountains and their Natural Monument #182. It’s referenced in dramas a ridiculous number of times(I think it may be the mountain they visit in Wish to See You Again but unfortunately I can’t remember) A volcanic peak, it’s South Korea’s highest point at 1950 meters

Beautiful, no? I hope I get to visit there someday. Apparently it’s often hidden by clouds and the natives compare it to a beautiful woman hiding her face.
