Naksan JeongSang is the highest point in Naksan Park in Seoul, a natural conservation area on a low hill about 124 meters above sea level. It offers views of the city and the night scenery. The Hanyangdoseong walking trail runs from Hyehwamun to Sungnyemun, and its flat, gently sloped course takes about an hour and a half. There is little space to rest at the top.
