The Seoul Metropolitan Government (SMG) has created the Yongmasan Skywalk Observatory on Seoul Trail Course 4 for clear views of both forest and city scenery. Seoul Trail is a citywide trekking route comprised of 21 connected paths that follow mountains, rivers, and village roads around the outer edge of Seoul. The full course extends for 156.5 km.

The Yongmasan Skywalk Observatory is the first project built under Seoul Trail 2.0 to add a fresh spatial experience. Yongmasan Mountain is the highest mountain in Jungnang-gu with an elevation of 348 m. The trail is well-maintained, allowing visitors to enjoy an easy walk with clear city views.

The skywalk stretches about 160 m and rises 10 m above the ground. It is a wooden deck path that crosses above the forest. The highest viewing point displays a panorama toward N Seoul Tower, Bonghwasan, Dobongsan, and the distant ridgeline of Bukhansan Mountains.

Nearby paths such as Yongmasan Jarak Trail, Jungnang Trail, and Manguri Trail connect to the area, convenient access.

The skywalk will be open on a trial basis until November 28, with hours set from 9 AM to 5 PM during this period. Full access will begin afterward.

The total number of full-course finishers on Seoul Trail reached 92,756 as of October 31, 2025, and is close to reaching 100,000. The city expects new spaces such as the Yongmasan Skywalk Observatory to draw more visitors to Seoul Trail and support both mental health and physical well-being for citizens.

Seoul will also build the Hoamsan Skywalk Observatory on Course 12 by late December to provide more to see and experience for visitors.
