Yonggwolsan Sky Trail (용궐산 하늘길): Cliff Decks Above the Seomjin River
Sunchang (순창) is a small county in North Jeolla Province (전라북도, Jeonbuk), better known for its gochujang (고추장, Korean fermented red pepper paste) than its scenery. But along the Seomjin River (섬진강), Yonggwolsan Mountain holds something worth the trip: a cliff-side deck trail that locals compare to Zhangjiajie in China — hence the regional nickname 순창의 장가계, “Sunchang’s Zhangjiajie.”The trail runs along sheer granite walls, with the river winding far below. We came as a family and had the same question most people do: is this actually manageable with kids? The stone path at the start is well-laid and stable. Small children move through the lower section without trouble. The wooden deck sections higher up take most of the footing challenge away — though the sheer step count is a different matter.This is the full record: parking, tickets, courses, the 1,300 stairs, the view from the top, and the charcoal BBQ dinner that followed.
Getting There and Parking
Search “용궐산 자연휴양림” (Yonggwolsan Natural Recreation Forest) in your navigation app. The final approach follows the Seomjin River — narrow road, no lane markings, two-way traffic. Fine for most drivers, but worth a heads-up if you’re less confident on Korean mountain roads.Most visitors stop near the lot entrance. That’s the farthest spot from the ticket booth. Drive a bit further in and you land right in front of it. The trade-off: the snack bar is a little farther from the inner spaces. We arrived around noon on a Saturday to a half-full lot.
Tickets, Hours, and What to Bring
Admission: ₩4,000 per person — adults and students, same rate, individual or group. Each ticket includes ₩2,000 in Sunchang Love Gift Certificates (순창사랑상품권), redeemable at participating shops within Sunchang County. Four tickets cost ₩16,000; we got ₩8,000 back in vouchers and used them at the snack bar on the way down.Hours:
March–November: 09:00–17:00
December–February: 09:00–16:00
Water. Non-negotiable. The deck stairs alone count to 1,300. The snack bar near the entrance sells water and snacks — buy before you head up. We left ours in the car. Learned the hard way.Near the entrance, dust-removal machines (흙먼지 털이기) are set up — a practical trail fixture for cleaning boots and gear after the descent.Dust-removal stations (흙먼지 털이기) at the trailhead — use on the way back down
Three Courses — We Chose the Sky Trail
Three marked courses start from the ticket booth:
Course
Distance
Time
Sky Trail (하늘길)
3.2 km
~2 hours
Yonggwolsan (용궐산)
6.1 km
~4 hours
Yongul (용굴)
5.7 km
~3 hours
The Sky Trail loops: ticket booth → Sky Trail cliff section → Biryongjeong (비룡정) pavilion → return to trail start → ticket booth.The Yonggwolsan course extends past Biryongjeong to the summit, then down through Naeryong Village (내룡마을) to Yogang Rock (요강바위). The Yongul course branches off to Dragon Cave (용굴) and Dragon Egg Rock (용알바위). Both share the cliff deck section — the Sky Trail covers it and turns around. We came for the cliff decks. Sky Trail it was.Yonggwolsan trail map (용궐산 등산로 안내) — three courses, all departing from the ticket booth
The Hike
The trail opens on stone. Flat rocks laid into the slope — well-fitted, stable underfoot. About 15 to 20 minutes of this before the wooden deck stairs begin. Kids move through without issues.Lower stone-step section — 15 to 20 minutes before the wooden deck stairs begin
Once the stone section ends, the numbered deck stairs take over. The count runs up to 1,300 by the time you reach Biryongjeong. Each post is numbered — you can track your progress, which is either motivating or demoralizing depending on the day.Step 1,300 — the deck stairs count all the way to Biryongjeong (비룡정)
For the first 70–80% of the climb, the views stay blocked — trees, cliff face, canopy overhead. Keep going. At the 80% mark, the granite opens up and the Seomjin River appears below, threading through a wide valley of layered green ridgelines. That’s when the effort starts to make sense.The 80% mark: Seomjin River (섬진강) opens below for the first time
From there, the steep climbing mostly stops. The trail flattens into wide deck sections built directly against the cliff face — railed on the outer edge, granite wall on the inner side. The exposure is real but there’s nothing dangerous about it. If you somehow stepped off path, rocks and trees would catch you long before anything serious. A cool breeze rolls in off the valley here. After the stairs, it lands well.The sky trail deck (하늘길) on the cliff face — flat walking from here to the pavilion
Along the cliff, large Chinese characters are carved directly into the granite. Classical Korean-Chinese carving tradition — common on older mountains in Korea, and a bit startling to come across mid-hike.Biryongjeong (비룡정), the open-air pavilion at the high point of the Sky Trail section, is a good place to stop. Sit, look at the valley. We moved through faster than planned — no water, counting the steps to the snack bar.The summit is reachable from here. We passed on it. The cliff deck is what this trail is about.
Coming Down and After
The descent retraces the same path. Take the stairs carefully — they feel steeper going down than up.From the base of the cliff, the deck structure reads differently: tiers of railing stacked against open granite, each level separated by bare rock.Chinese characters carved into the granite base — the deck trail runs above
Below the parking lot, a path leads down to the Seomjin River bank — worth the extra few minutes if your legs have anything left.Round trip: about two hours, including breaks and photos. Difficulty: medium. The 1,300 stairs are the main variable — sustained but not technical. Anyone with a baseline of regular exercise gets through it without trouble.
Dinner in Imsil: Charcoal BBQ with Makchang (막창)
We were staying in Imsil (임실), a small town about 20 minutes from Sunchang. Dinner in the town center — a local charcoal BBQ place specializing in makchang (막창, pork large intestine grilled over charcoal).Two signals that it’s the real deal: reservations are needed, or you arrive before 6 p.m. By early evening, the place is full. In a town this size, a consistently packed house means something.Inside: compact. Partitioned booths along the walls, a bar-counter row down the center.We ordered samgyeopsal (삼겹살, pork belly), beef galbi strips (소갈비살), makchang (막창), and dwit-deolmusal (뒷덜미살, pork neck). The table came with meoljeot (멜젓, salted fermented anchovy dipping sauce) and baekkimchi (백김치, white kimchi without chili) — both worth throwing on the grill alongside the meat. Post-hike appetite is real. The pace of eating was not moderate.Imsil and Sunchang together don’t get much international attention, but the trail and the dinner made a day worth repeating. If you’ve already been to this corner of Jeonbuk (전라북도), or if Yonggwolsan is on your list — drop a note in the comments. Curious what brought other visitors out this way.
