The Naksan Mountain Trail of the Seoul City Wall covers an enjoyable scenic route beginning from Hansung University Station and the Hyehwamun Gate, travelling south alongside Naksan Park and Ihwa Mural Village, and leading to the crowded, neon streets of Dongdaemun with the landmark Dongdaemun Gate at the foot of the trail. The fortress trail just takes less than an hour to walk. There are fantastic views across the city as you follow the path, especially at sunset.
