Seoraksan National Park stands fiercely radiant in autumn, its peaks pushing upward as if daring you to match their climb. Hiking here across the fall foliage isn’t a casual stroll but a deliberate engagement with nature that’s both relentless and gorgeous. The park’s rocky ridges and forested valleys are draped in reds, burnt oranges, and golds, threaded through with the whisper of crisp, cool wind and the crunch of leaves underfoot.

Starting from the main entrance near Sokcho city, the well-marked Ulsanbawi Rock trail rises rapidly over 5 kilometers with an elevation gain of about 800 meters. This path demands steady effort: rocky steps, occasional chains for assistance, and narrow ledges that test balance. The forest canopy is a lively crowd — maples and ginkgo push their colors forward, framing panoramic views of jagged peaks and the East Sea shimmering in the distance.

Hydration is non-negotiable; cool autumn air can mask hidden dehydration. Sturdy hiking boots that grip on mossy stone and leaf-littered paths will keep your footing sure. Early morning or late afternoon hikes offer softer light that reveals the depth and contour of the foliage, while mid-day is best reserved for rest and replenishment.

Trailheads can get busy on weekends during peak foliage, so weekday excursions will grant a quieter experience. Allow 4 to 6 hours for the full circuit from parking to summit and back, pacing yourself to absorb the environment but respecting the toughness beneath the beauty. The park commands respect — weather shifts quickly, and the terrain insists on focus and respect.

Along the routes, streams chat with urgency and cliffs wear their age openly. Don’t rush past them. Each scene is a challenge of its own, a fiercely independent aspect of Seoraksan that rewards patience and persistence. In autumn, the mountain isn’t just a backdrop but an active participant, inviting you to test your endurance against its time-honed stone and seasonal flames.
