Seoul is often described as a fast, modern megacity — but one of the best ways to truly understand it is by walking its historic edge.
The Seoul Hanyangdoseong Completion Challenge is an 18.6 km city hike that follows the ancient fortress wall surrounding old Seoul.
It’s a unique urban trekking experience where mountains, neighborhoods, history, and skyline views all connect into one continuous walking route.
For travelers who enjoy city hiking, urban trekking, or walking-based exploration, this challenge is one of the most rewarding ways to experience Seoul.
What Is the Seoul Hanyangdoseong?
Hanyangdoseong is the fortress wall built during the Joseon Dynasty to protect the capital city, Hanyang (present-day Seoul).
Today, much of the wall remains intact, and a continuous walking trail has been created along its path.
The full route forms a loop of approximately 18.6 km around central Seoul.
The trail connects four mountains:
Along the way, walkers experience:
- Historic stone fortress walls
- Forested mountain paths
- Residential neighborhoods
- Wide views over modern Seoul
It’s a rare chance to walk through 600 years of history inside a living city.

Why This Is a “Completion Challenge”
The Seoul Hanyangdoseong route is designed as more than a casual walking trail.
It’s officially operated as a completion-based walking challenge, giving walkers a clear goal and a sense of achievement.
Participants complete the challenge by:
- Walking each official section of the trail
- Taking verification photos at designated spots
- Submitting their records online
Once verified, walkers receive official completion rewards.
Quarterly Completion Badges: What Makes This Challenge Special
One of the most motivating parts of the Seoul Hanyangdoseong Completion Challenge is its quarterly badge system.
- Each quarter of the year offers a different color completion badge
- Completing the challenge in different quarters allows you to collect multiple badge colors
- The badges change every quarter, encouraging repeat visits across seasons
This means walking the same route in spring, summer, fall, or winter feels like a new challenge each time, with its own reward.
For many walkers, collecting these seasonal badges becomes part of the fun — not just finishing the trail once, but experiencing Seoul in different moods throughout the year.
How the Completion Challenge Works
The challenge is flexible and traveler-friendly.
- Start at any section of the trail
- Walk at your own pace
- Take verification photos at official points
- Submit your completion online
- Receive your certificate and seasonal badge
You can complete the full 18.6 km:
- In one day (for experienced walkers)
- Over several days
- Or spread across multiple trips to Seoul
There’s no fixed order or schedule, making it ideal for independent travelers.
