Overview
Biryong Falls (비룡폭포) is the easy signature waterfall hike at Seoraksan's main entrance — a 4.8 km out-and-back along a clear forest stream that ends at a 16 m waterfall. Where Ulsanbawi punishes you with 808 stairs and Daecheongbong demands a full alpine day, Biryong asks for a comfortable pair of shoes and an hour and a half.
This is the right trail when you want to be inside Seoraksan but not on it — a half-day option that delivers genuine park scenery without the cardio of the bigger names.
The Route
Sogongwon Entrance → Yukdam Falls (1.4 km): After the park entrance fee, the trail follows the Sogongwon-side stream upstream. The path is wide, well-maintained, and gently graded — comfortable for almost any fitness level. About 1.4 km in you reach Yukdam Falls (육담폭포) — six small, stair-stepped pools cascading through a tight rock canyon. Most travelers stop here for photos.
Yukdam Falls → Geumganggul Bridge (0.4 km): Just above Yukdam the trail crosses the bright red Geumganggul (금강굴) suspension bridge — short, photogenic, and a useful waypoint. The forest tightens here and the stream noise picks up.
Geumganggul → Biryong Falls (0.6 km): This is the only meaningful climb on the trail — a series of stone steps and short rocky stretches. It's the part that decides whether you arrive at the falls in 30 minutes or 50, depending on pace. The waterfall is dramatic: a single 16 m drop into a small pool, fed year-round by the upper Seorakdong watershed.
What to Expect
This is a maintained tourist trail, not a wilderness route. Expect:
- Other people — Biryong is one of Seoraksan's most accessible trails. Weekend afternoons in autumn can feel busy, especially the first 1 km.
- A stream the whole way — the route never strays far from running water, which is most of the appeal.
- Limited shade on hot days — the canyon section past Yukdam is partially exposed.
- Good footing — sturdy walking shoes are fine; full hiking boots are not necessary.
The last stretch from Geumganggul Bridge to the falls is the only part where you'll feel like you're hiking. Stone steps, occasional roots, and one short stairway. Take it slow with kids and on damp days.
How to Get There
The Biryong Falls trail starts from the same Sogongwon (소공원) entrance as the Ulsanbawi route and the Seoraksan Cable Car. Practical access:
- Bus: Bus 7 or 7-1 from Sokcho Intercity Bus Terminal — about 20–25 minutes, ₩1,530 by card.
- Taxi: From central Sokcho, 15 minutes, ₩12,000–₩15,000.
- Car/Parking: Paid parking at the Sogongwon lot — ₩6,000 for a standard vehicle. Fills early on autumn weekends.
After the park ticket booth, the Biryong trail branches off to the right (south side of the stream). It is signposted in Korean and English; the trailhead board labels it 비룡폭포 / Biryong Falls.
When to Go
- Spring (April–May): the stream runs full from snowmelt; the canyon is at its loudest and greenest.
- Autumn (mid-October to early November): the maple and pine canopy turns; Yukdam Falls is the photo stop.
- Summer: comfortable temperatures inside the canyon even when the city is hot, but afternoon rain is common — start before noon.
- Winter: open but icy. The falls partially freeze from late December through February; microspikes make the difference between a pleasant walk and a tense one.
Biryong Falls pairs beautifully with the Seoraksan Cable Car for a no-stairs half-day plan: cable car in the morning, lunch near Sogongwon, Biryong in the afternoon. Both share the same entrance area, so you only pay parking once.
