The wall was built using stones of different sizes and textures, reflecting the specific construction technology of the era in which each section was renovated.
Inscribed characters on many of the stones indicate the names of the regional officials and craftsmen responsible for that specific segment of the wall.
The trail features the 'Four Great Gates' and 'Four Small Gates,' which traditionally served as the only entry points into the capital city.
King Taejo, the founder of the Joseon Dynasty, mobilized over 190,000 workers to complete the initial wall construction in just over two months.
Certain sections near Bugaksan were restricted for decades due to security concerns near the presidential residence and only reopened fully to the public in recent years.
The Seoul City Wall Trail follows an 18.6-kilometer fortress wall originally constructed in 1396 during the Joseon Dynasty. It encircles the historic center of Seoul, connecting four major mountains: Bugaksan, Namsan, Naksan, and Inwangsan. The trail is divided into six distinct sections, each offering varying levels of terrain difficulty and historical perspectives. It served for centuries as a defense barrier, though significant portions were destroyed during the 20th century. Modern restoration efforts have reclaimed large segments of the wall, incorporating watchtowers and traditional gates. The trail serves as an urban hiking route that bridges ancient stone masonry with contemporary city skylines. Parts of the path run directly through residential neighborhoods, including the steep slopes of Changsin-dong. The trail is fully managed by the Seoul Metropolitan Government, which maintains markers and educational signage along the route.
The elevated point at Naksan Park providing a direct sightline of the wall snaking through the Seoul skyline at dusk.
Start with the Naksan section for a gentle, paved walk that offers panoramic views of the city with minimal incline.
Wear sturdy hiking shoes, as some sections involve uneven ancient stone stairs and steep natural trails.
Bring your own water and snacks, as facilities are scarce on the mountain-top portions of the trail.
Attempting the entire 18.6km length in a single day without prior hiking experience; failing to check section-specific closures.
Mountainous sections (Bugaksan/Inwangsan) may close during high-wind or extreme weather events; some sections remain closed on Mondays for maintenance.
Stay on marked trails to protect the stonework; do not climb or lean on the historic wall sections.
