Naksan Seonggwak-gil is a walking trail along the Hanyangdoseong city wall that connects Hyehwamun and Heunginjimun, running through the Naksan section above Ihwa-dong and Changsin-dong. Inside the wall, residential streets and cafes continue, with views of Dongdaemun, central Seoul, and Seongbuk-dong. The route from Hyehwamun to Heunginjimun is about 2.1 km, and the section leading to Naksan Park is the shortest and easiest of the Hanyangdoseong sunseong Course 2. The trail has uphill sections, so walking up is difficult.
