Seoraksan National Park: Hiking Trails, Seasonal Highlights & Visitor Tips

Seoraksan National Park sits in the northeast of South Korea, in Gangwon Province, where the Taebaek mountain range drops toward the East Sea in a jumble of granite spires, deep valleys and temple-dotted forest. Its highest peak, Daecheongbong, rises to 1,708 metres, and the trails range from flat riverside strolls to full-day ridge scrambles. This guide covers the main hiking routes, what the park looks like through each season, how to base yourself in nearby Sokcho, and the practical details that decide whether a day on the mountain goes smoothly.

Why Seoraksan Stands Apart

South Korea has 23 national parks, and Seoraksan is the one most people name first when asked about dramatic scenery. The reason is geological. Rather than the rounded, forested ridges common elsewhere in the country, Seoraksan is built from bare granite that has been cracked, split and polished into pinnacles, domes and sheer faces. The name roughly translates as “snowy crag mountain,” a nod to the pale rock and to how early snow dusts the high peaks while valleys below are still green.

The park was designated in 1970 and later recognised by UNESCO as a Biosphere Reserve, which reflects how much wildlife survives here, including the endangered Korean long-tailed goral, a goat-antelope that clings to the cliffs, and musk deer. You will rarely see either. What you will notice is the way the landscape works as a living gallery: waterfalls hidden behind bends, temples tucked below rock walls, and a constant sound of running water almost anywhere you walk.

Entry to the park itself no longer costs anything, although individual attractions such as temples, the cable car and some car parks do charge. That makes Seoraksan one of the most accessible big mountain landscapes in Asia, and it also explains the crowds on autumn weekends.

Reading the Map: Outer, Inner and Southern Seorak

The park is traditionally split into three areas, and choosing between them shapes your trip more than any other decision.

Outer Seorak (Oe-Seorak)

This is the side facing the sea and the one closest to Sokcho. Most first-time visitors start at the Seorak-dong entrance, where short trails lead to Sinheungsa Temple, the cable car and the waterfalls. Facilities are the best here, buses are frequent, and the rock scenery is at its most photogenic.

Inner Seorak (Nae-Seorak)

Inland and on the western side of the main ridge, Inner Seorak is quieter, more forested and more remote. Access is via the Baekdam Valley and Baekdamsa Temple in Inje County. It suits hikers who prefer long river valleys to sightseeing.

Southern Seorak (Nam-Seorak)

The southern section is reached from Osaek, a small hot-spring settlement. Its trails climb steeply and are used mainly for the shortest ascent to Daecheongbong. Osaek is also the logical stop for hikers who want a soak afterward.

Moving between sections by road takes time because the range blocks direct routes. Most visitors pick one side per trip, and for a first visit Outer Seorak is the sensible choice.

Gentle Walks from Seorak-dong

The park entrance at Seorak-dong opens onto a broad, mostly flat path beside a stream, and this stretch alone justifies a visit if you have limited energy or time. The first landmark is Sinheungsa Temple, believed to have been founded in the seventh century and rebuilt several times after fires and war. The bronze Unification Buddha, nearly 15 metres tall, sits outside the temple grounds and faces the mountains, a symbol of hopes for reunification of the peninsula. The temple’s setting, with granite walls rising behind the main hall, is among the best in the park.

Beyond the temple, a short side trail leads to Heundeulbawi, a huge boulder balanced on a rock shelf at the edge of a ledge. Visitors take turns pushing it, and with the right technique it rocks back and forth, despite weighing many tonnes. It is a good reward for a walk that takes well under an hour at an easy pace from the temple.

Continue a little further along the valley and you reach Biseondae, a flat rock terrace beside a clear pool and under a high wall of granite. Legend says that immortals came down from the heavens to rest here. Whether or not you believe it, the spot is ideal for a picnic or a rest before heading back. A round trip from the entrance to Biseondae is manageable in two to three hours including stops, and trails are wide and well graded, which makes this a comfortable outing for families and older travellers.

Gwongeumseong by Cable Car

The cable car near the park entrance takes about five minutes to climb to a station just below the ruined Gwongeumseong fortress. From there a steep stone and metal stair path climbs for roughly 15 to 20 minutes to a rocky summit at around 800 metres. It is short but not trivial: the steps are uneven and the air gets noticeably cooler and windier at the top.

The reward is a full 360-degree panorama. On a clear day you see the serrated Dinosaur Ridge to the west, the valleys of Outer Seorak below, and Sokcho with the East Sea beyond. The fortress itself is mostly a scatter of stone remains, but it gives the viewpoint a sense of history, since it was a defensive position during the Goryeo dynasty.

Queues for the cable car can be long on autumn weekends, sometimes more than an hour, and the service may stop in strong wind or heavy snow. Arriving at opening time or late in the afternoon avoids the worst of the wait. If you prefer to earn the view, a steep walking trail runs beside the cable car route, though many walkers find the descent hard on the knees.

Ulsanbawon: The Iconic Granite Climb

Ulsanbawon is a cluster of six granite peaks that look like a stone screen, and it is probably the most recognised silhouette in the park. According to local legend the rocks were meant to travel to the Diamond Mountains in present-day North Korea but arrived too late, and so they stayed in Seorak. The summit sits at about 873 metres.

The trail begins at Sinheungsa and runs roughly 3.8 kilometres one way. The first half is gentle and follows the valley, passing the cable car and a few small shrines. The second half is steeper, ending with a long climb of well over 800 steps up a metal staircase bolted to the rock face. Allow around four hours for the round trip at a moderate pace, a little more if the stairs are crowded.

The view from the top looks over the spiky ridgelines of Seoraksan on one side and the sea on the other. It is one of the best payoffs per kilometre in the country. People who dislike heights may find the final staircase uncomfortable, since parts are open and the drop is clear. The stairs also close when winds are strong or ice makes them unsafe, so check conditions at the visitor centre before you commit.

Waterfall Valley Hike: Biryong, Towangseong and Yukdam

Another route out of Seorak-dong follows the Cheonbuldong Valley toward a series of waterfalls. It is one of the best walks in the park for people who want water, shade and moderate effort without climbing a peak.

The first major stop is Biryong Falls, a double-tiered cascade that drops through a narrow rock gorge. A viewing platform sits just below, and the spray cools the air even in summer. Further along is Towangseong Falls, a trio of waterfalls on a separate branch of the valley, best seen after rain when the flow is strong. The trail then continues to Yukdam Falls, a sequence of six pools linked by cascades and framed by high cliffs.

Walking from the entrance to Yukdam Falls and back takes about four to five hours depending on the extent of side trips. The paths are rocky in places and can be slippery in wet weather, so decent footwear matters more than usual. The reward is a hike that feels remote without requiring ridge-walking experience.

In dry seasons the flow can shrink noticeably, so late spring after snowmelt and the weeks after summer rains are the best times for the falls.

Summit Routes: Daecheongbong and the Dinosaur Ridge

Daecheongbong is the third-highest peak in South Korea, and reaching it is the goal of most serious hikers who visit. There are two main ways up.

The shortest is from Osaek in Southern Seorak, a climb of around five kilometres one way that gains elevation almost continuously. It typically takes three to four hours up and a little less down. The path begins gently along a stream and then turns into steps and rocky switchbacks. Hikers who start early are often at the summit before clouds arrive.

The longer route starts in Outer Seorak, passing Sinheungsa, Biseondae and a mountain shelter before the final ascent, and totals more than ten kilometres one way. That makes it a demanding full-day outing, or a two-day trip with a night in a shelter.

For experienced hikers, the Dinosaur Ridge (Gongnyongneungseon) is the park’s signature challenge. This long ridge walk follows a spine of rock with exposed sections and sweeping drops on both sides, and it can take ten hours or more. It is physically demanding and the weather can change quickly. It is not a route for beginners, and the park service may restrict access in bad conditions.

Whichever route you choose, start before dawn, carry more water and food than seems necessary, and be prepared for the summit to be several degrees colder than the trailhead. Rangers set cut-off times at trail entrances, and these are enforced.

Inner Seorak: Baekdamsa and Suryeomdong Valley

The western side of the mountain is a different experience. Baekdamsa Temple lies at the end of a long valley road in Inje County and has a quieter, more meditative feel than the temples near Sokcho. The poet and Buddhist reformer Han Yong-un, known by the pen name Manhae, lived here for a time and wrote part of his best-known work, and the temple has a small memorial to him.

The valley trail from the temple follows a clear stream through a corridor of pools, rocks and rounded boulders. The walk to Suryeomdong, a valley where waterfalls drop through a narrow cleft, is roughly seven kilometres one way and takes about two and a half to three hours. Along the way, stone cairns built by passing hikers line the water. The scenery is gentler than Outer Seorak, with thicker forest and fewer vertical cliffs, but the trails are far less crowded.

Public transport to Baekdamsa is limited and some visitors drive or take a taxi from nearby towns. That distance filters out many casual visitors, which is exactly why some regulars prefer this side. Several temples in the area, including Baekdamsa, have offered temple-stay programmes, though availability and details should be checked in advance.

Seasonal Highlights

Spring

Spring arrives late at altitude. Cherry blossoms and forsythia show in the lowlands from April, and azaleas colour the higher slopes in May and early June. Snow can linger on the upper trails into April. Many routes are closed for part of spring for fire prevention, so check the schedule before planning.

Summer

Summer means lush forest, strong waterfalls and humidity. Monsoon rains between late June and July can swell streams and close some trails. Valley hikes are pleasant, but ridge walks can be hot and storms build quickly in the afternoon. Beaches in Sokcho offer a good way to cool down afterward.

Autumn

Autumn is peak season. Foliage typically starts on the upper slopes of Daecheongbong in late September or early October and moves downhill, reaching the valley floor around late October. The colour contrast between red maples and pale granite is the park’s most famous image. It is also when crowds are at their heaviest, with queues for the cable car and packed trails on weekends. Weekdays and early mornings are far calmer.

Winter

From December to March the park is covered in snow, and the rock formations look sharper against white slopes. Lower trails remain walkable, but icy sections require crampons or microspikes, and some high routes close. Winter visitors get far fewer people and a quiet, stark beauty, with temple roofs frosted and streams partly frozen.

Sokcho as a Base: Harbour Town Character

Sokcho is the practical gateway to Outer Seorak, but it has enough personality to make it more than a place to sleep. This is a working fishing port, with squid boats, fish markets and seafood restaurants lining the waterfront. Its story is closely linked to the Korean War, when many refugees from the north settled here, and that history still shapes the food and local identity.

The city sits between the mountains and the sea, so the same day can include a morning hike and an afternoon on the beach. Sokcho Beach has a long, wide stretch of pale sand and a promenade that fills with walkers in the evening. A short walk from the main fish market leads to Abai Village, a former refugee settlement where residents once crossed the narrow Cheongchoho channel on a hand-pulled cable ferry. The ferry still runs and gives a small taste of local history.

Further out, Yeongnangho Lake and the Sokcho Lighthouse viewpoint provide quieter spots for a sunset walk. The city is compact enough that you can reach most of these places on foot or by short bus rides, and it feels relaxed compared to Seoul or Busan.

What to Eat: Sokcho and Mountain Flavours

Food is a strong reason to spend a night or two in the area. Sokcho specialises in seafood, but the mountains add their own dishes, so you can eat well in both settings.

• Squid sundae (ojingeo sundae): squid stuffed with a mixture of vegetables, glass noodles and sometimes rice, then steamed and sliced. It is a Sokcho signature, and Abai Village is known for its version.
• Dakgangjeong: crispy fried chicken in a sweet, sticky sauce. Sokcho’s central market is famous for it, and queues often form at the most popular stalls.
• Mulhoe: a cold, spicy raw fish soup, usually served with noodles. It is refreshing after a summer hike.



• Snow crab and fresh fish: the port at Daepo is the place for crab in winter and a long list of sashimi options year round.
• Sanchae bibimbap: a mountain-vegetable version of the classic rice bowl with wild greens, mushrooms and roots. Restaurants near the Seorak-dong entrance serve it with pajeon (savoury pancake) and makgeolli (milky rice wine).
• Soft tofu: the Gangwon coast is known for tofu made with seawater, and several restaurants near Sokcho specialise in it.

Eating near the park entrance is convenient but can be pricier and more tourist-oriented. The central market and harbour offer better value and more variety.

Getting There and Getting Around

Most visitors travel from Seoul. Express buses run from Seoul’s Express Bus Terminal and Dong Seoul Terminal to Sokcho, and since the opening of the Seoul–Yangyang Expressway the journey takes roughly two and a half hours in normal traffic. Buses are frequent, comfortable and the easiest option. Travelling by train is possible by taking the KTX to Gangneung and then continuing by bus, though that is slower for Sokcho itself.

From Sokcho’s bus terminal, local city buses run to the Seorak-dong entrance in about 30 to 40 minutes. Services are frequent in the daytime and extra buses run in peak foliage season. A taxi is a fair alternative if you are in a group. For Osaek and Baekdamsa, services are less frequent, and checking timetables in advance is wise. Many hikers hire a taxi or drive for those areas.

Inside the park, almost everything is reached on foot. Parking near the main entrance fills early on busy days, so public transport is often faster even if you have a car. If you drive, carry some cash for parking and a few small tolls.

Where to Stay

The best choice depends on the kind of trip you want.

Sokcho offers the widest range, from guesthouses and business hotels to beachfront resorts. It has restaurants, markets and transport links, which makes it easy for non-hikers or mixed groups. Staying here means a daily bus ride to the park.

Seorak-dong is the cluster of hotels and pensions along the road leading to the main park entrance. It is the most convenient for early starts, and staying here lets you reach the trailheads before the day-trippers. The trade-off is fewer dining options and higher prices in peak season.

Osaek is a hot-spring village on the southern side. Its mineral-rich waters are known for soothing tired muscles, and a few hotels have their own bathing facilities. It suits hikers planning to climb Daecheongbong from the south.

Mountain shelters on the high trails can be reserved through the national park service, which is useful for multi-day routes but requires advance booking, especially in autumn. Weekends in October book out weeks ahead, so reserving early matters wherever you stay.

Day Trips Beyond the Park

The surrounding coast and hills add variety if you have more than a couple of days.

• Naksansa Temple, Yangyang: a seaside temple perched on cliffs, famous for a statue of Haesu Gwaneum, the Guanyin of the Sea, and for sunrise views. It is about 30 to 40 minutes south of Sokcho by road.
• Gangneung: a larger coastal city with coffee shops along Anmok Beach, the Gyeongpo Lake area and traditional houses such as Ojukheon. It makes an easy half-day or full-day trip.
• Goseong and Hwajinpo Lake: heading north brings quieter beaches and a coastal lagoon. The Unification Observatory looks across the border toward North Korea, though visits require advance registration and rules can change.



• Daepo Port: just north of Sokcho, a small harbour with a market and some of the freshest seafood in the area.

Practical Tips: Closures, Gear, Timing and Safety

A few practical points prevent most problems at Seoraksan.

• Check trail status first. The Korea National Park Service closes certain routes for seasonal fire prevention, usually in spring and late autumn into early winter, and also after storms or heavy snow. Confirm your route is open before leaving.
• Start early. Trails have entry cut-off times, and daylight shortens quickly in autumn and winter. Plan to be off the mountain before dusk.
• Wear proper footwear. Granite gets slippery when wet. Hiking boots or sturdy trail shoes with good grip are better than sneakers.
• Dress in layers. The temperature drop between the valley and the summit can be significant, and wind at higher points is cold even in summer. Pack a waterproof shell.
• Bring enough water and food. Water sources on long routes are limited, and shops are only found near the main entrance and a few trail points.
• Use trekking poles on steep descents. Many Korean hikers do, and they protect knees on long stair sections.
• Carry some cash. Small vendors, parking and some temple entrances may not accept cards.
• Respect the rules. Staying on marked trails, avoiding open fires and carrying out rubbish are enforced, and fines apply for breaches.
• Know the emergency number. Dial 119 for mountain rescue. Mobile reception is patchy in deep valleys, so tell someone your route before setting off.

With a flexible plan, a few good layers and an early alarm, Seoraksan rewards visitors of nearly every fitness level. The easy valley walks give a taste of the scenery, the big summit routes challenge experienced hikers, and the harbour town below provides a warm, flavourful end to the day.
