Bukhansan National Park Main Ridge

Bukhansan National Park Main Ridge claims the top spot as the most-used national park trail worldwide by visitor density, with over 5 million annual visitors traversing the granite ridge from Dobongsan to Baegundae summit at 836 meters. Its mix of dramatic rock scrambling and ancient fortress walls delivers panoramic Seoul views, especially during autumn foliage season. Compared to #2 Hallasan Summit Trail, Bukhansan offers more accessible yet equally rewarding climbs within a metropolitan setting, outperforming typical park trails with its urban proximity and historical fortress remnants, such as the 2.3-kilometer Bukhansanseong Fortress wall.
