A short walk
Naksan is one stretch of wall, not Bukhansan. Go up from Hyehwamun, and come down once you have the view. Do not turn it into a hike. Dongmyo can follow. If you eat, one bowl at the Yangnyeong herb market, then stop. Do not continue to Gwangjang for a second meal, and do not continue to Daehak-ro or Dongdaemun for a second night. Incheon and Gimpo are not on this map. In rain, indoors at the herb market. Save the wall for a clear day. Once the wall has given you the view, come down. The bowl at Yangnyeong is the half-day's food. It is not a ticket to Gwangjang. Hyehwa station is the way back. Do not transfer to a Daehak-ro night. Hyehwa station is the exit for this half-day. Once the wall has given you the view and the bowl is finished, board the train.
