Hiking in Korea — Best Mountain Trails for Every Level — is not just a weekend activity here; it is practically a national religion, and once you lace up your boots and step onto one of these granite ridgelines with the wind cutting across your face and a sea of autumn color spreading out below you, you will understand completely why Koreans treat the mountains with the same devotion they give to family. I have been hiking these trails for over twelve years, and I still find myself genuinely moved every single time I reach a summit. What makes Korea’s hiking scene so extraordinary is the sheer variety packed into a relatively small country — you can be scrambling up a rugged volcanic peak on Jeju Island one weekend and navigating a forested temple path in the heart of Seoul the next.
The Korean mountains are not remote, either, which is part of what makes them so addictive. Most of the best trailheads are accessible by subway or direct bus within an hour or two of any major city. Bukhansan rises dramatically right behind the northern neighborhoods of Seoul, Hallasan crowns Jeju like a sleeping giant, and Seoraksan in Gangwon Province delivers the kind of dramatic rocky scenery that looks photoshopped but is completely real. Whether you are a first-timer who needs a gentle forest walk or a seasoned trekker hunting for a technical ridge traverse, Korea’s mountain trail network has something that will stop you in your tracks — in the best possible way.
Seoul’s Best Mountain Trails — Hiking Right From the City
Bukhansan National Park is the trail that most first-time hikers in Korea tackle, and honestly, it earns its reputation every single time. The most popular route is the Baegundae Peak trail, which climbs to 836 meters and rewards you with a 360-degree view of the entire Seoul skyline framed by jagged granite spires — it genuinely does not look real. Take Line 3 to Gupabal Station, Exit 1, then grab Bus 34 directly to the Bukhansan Ui entrance. The round trip takes roughly four to five hours at a comfortable pace, and entry to the national park costs ₩1,000 (about $0.75) per person — yes, really, less than a can of coffee from the vending machine at the trailhead. One thing only locals know: start before 7 AM on weekends. By 9 AM, the main trail to Baegundae is genuinely shoulder-to-shoulder crowded, but in those early morning hours, you will have the granite slopes almost entirely to yourself with mist still clinging to the valleys below.
For an easier Seoul mountain hike that still delivers serious scenery, Inwangsan (338m) is my personal recommendation for beginners and anyone short on time. You can reach the trailhead on foot from Gyeongbokgung Station (Line 3, Exit 2) in about twenty minutes, walking through the Chebu-dong neighborhood. The trail winds past a genuine shamanist ritual site, ancient city wall fortifications, and Buddhist shrines tucked between boulders — all within the city limits of a metropolis of ten million people. The full loop takes under two hours and costs nothing. I have brought countless visitors here and every single one has said some version of “I cannot believe this is just here, in the city.” That reaction never gets old for me.
At Bukhansan, skip the crowded Baegundae course on autumn weekends and instead take the Jingwan-dong entry to the Bibong Peak trail — it is quieter by 80%, the foliage is just as spectacular, and you will pass Bukhansanseong Fortress walls that most tourists never see. The trailhead is a short taxi ride from Gupabal Station and costs roughly ₩5,000 (~$3.75) from the subway exit.
Intermediate Mountain Trails — Where Korea’s Hiking Scene Gets Serious
Once you have the Seoul trails under your belt, Seoraksan National Park in Gangwon Province is the natural next step — and it is where hiking in Korea truly begins to feel epic. The Daecheongbong Peak course (1,708m) is the most demanding day hike on the peninsula outside of Jeju, but the Ulsanbawi Rock circuit is the sweet spot for intermediate hikers: a 6km round trip with a 900-step iron ladder staircase bolted directly into the rock face that leads to one of the most theatrical viewpoints in all of Northeast Asia. Take the Dong Seoul Bus Terminal express bus to Sokcho (₩16,800 / ~$12.50, about 2.5 hours), then a local bus 7 or 7-1 directly to the Seoraksan park entrance. Entrance fee is ₩3,500 (~$2.60) for adults. The Ulsanbawi trail takes three to four hours round trip, and I strongly recommend going in mid-October when the maple and oak forest below those pale granite towers turns every shade of red, orange, and gold simultaneously — it is
