Hiking in Korea: Bukhansan, Seoraksan, and the Best Trails
Plan your trip
Hiking in Korea is not a niche interest. On any given weekend, millions of Koreans take to the trails in matching technical gear, stop at the summit for a meal brought in their pack, and return to the city in time for dinner. The national parks fill to capacity. The trails near Seoul require an early start to beat the crowds. The gear culture is sophisticated — Blackyak, K2, and Kway are Korean outdoor brands with serious technical reputations.
The mountains are accessible. Over 20 national parks protect the best terrain, most with well-maintained trails, staffed information centers, and food vendors at the trailheads. Summit makgeolli — a tradition of drinking rice wine at the peak — is a social ritual, not a joke.
Bukhansan: Seoul’s Mountain
Bukhansan National Park sits within Seoul’s city limits and handles more visitors per square kilometer than almost any national park in the world. The park’s two main peaks — Baegundae (836m, the highest) and Insubong — dominate the northern Seoul skyline.
Main Trails
Baegundae Summit Trail (from Bukhansan-ui IC entrance):
- Distance: 3.5km one way (7km return)
- Elevation gain: 700m
- Time: 3-4 hours return
- Difficulty: Moderate to strenuous. The final approach to the summit involves steel cables bolted into granite — not technical climbing but requiring hands.
The view from the summit over Seoul is the best urban mountain view in Asia. The city extends in every direction; on clear days Incheon’s port is visible to the west and the mountains of Gyeonggi Province to the north.
Insubong (Rock Climbing): The granite dome of Insubong is Korea’s most important traditional climbing destination. The routes (hundreds of them, graded on Korean and UIAA systems) range from beginner multi-pitch to serious technical lines. Korea Alpine Club runs weekend beginner sessions; equipment rental available at the trailhead.
Bukhansanseong Fortress Trail: A 7km circuit following sections of the ancient mountain fortress walls, with gates, watchtowers, and the fortress grounds accessible throughout. Less strenuous than the Baegundae summit; historically interesting; the walls themselves are photogenic.
Getting There
Bukhansan-ui Station (Line 4, extended): Exit 1, then shuttle bus or 20-minute walk to the main trailhead. Early start essential on weekends — the shuttle buses fill by 8am.
Seoraksan: Korea’s Most Dramatic Mountain
Seoraksan National Park (설악산) in Gangwon Province is the most visually dramatic mountain landscape in Korea. Granite peaks, deep valleys, waterfalls, and a Buddhist temple complex (Sinheungsa) in the foothills combine to produce the landscape that appears on Korean autumn foliage photographs.
Key Trails
Daecheongbong Summit Trail (from Seoraksan bus terminal):
- Distance: 7.7km one way (15.4km return) or 25km loop
- Elevation gain: ~1,650m
- Time: 10-12 hours for the summit and return
- Difficulty: Strenuous. Requires a full day and early start.
Daecheongbong (1,708m) is the highest peak in South Korea outside Jeju. The trail crosses several secondary peaks and valleys; the views from the summit ridge on clear days are the best in the Korean mainland mountains.
Inner Seorak (Outer vs. Inner routes): The park is divided into Outer Seorak (the peaks and approaches from Sokcho) and Inner Seorak (the Baekdam Valley from Inje). The Inner Seorak valley trail is less crowded, more remote, and more beautiful for its combination of stream gorge and forest. The Baekdamsa Temple at the valley head is accessible in a 6km walk from the Inner Seorak entrance.
Biseondae Rock: A large flat granite slab in the Outer Seorak accessible in a short 1km trail from the main entrance — the most accessible viewpoint in the park, crowded accordingly.
Ulsanbawi Rock: A 873m granite formation accessible via 3.7km trail. The final approach is steel ladders and steps cut into the rock. The view of the formation from below and the view from its summit are both excellent.
Getting There
Sokcho is the gateway city. Express buses from Seoul (East Seoul Terminal or Seoul Express Bus Terminal): 2.5-3 hours. From Sokcho, local buses connect to the park entrance (30 minutes).
Staying Near Seoraksan
Sokcho has the full range of accommodation. Seoraksan Resort at the park entrance has the most convenient access but the poorest value. Guesthouses and minbak in Sokcho are better priced. Hanwha Seoraksan Resort for a higher comfort level.
Jirisan: The Sacred Mountain
Jirisan (지리산, 1,915m) is the highest mountain in South Korea on the mainland (Hallasan on Jeju is higher) and one of the country’s most revered — it’s been considered sacred since ancient times and has multiple Buddhist temples at various altitudes.
The Jirisan Ridge Trail (종주 코스) is a famous 47km traverse across the entire mountain range, taking 2-3 days with overnight stays at the trail shelters (sanjangsso). It requires advance booking of the shelters and proper preparation — this is a genuine multi-day mountain traverse at serious altitude.
For day hikers: Nogodan Peak (1,507m) from Seongsamjae trailhead (accessible by bus from Gurye) gives the ridge views without the full traverse commitment. 4-5 hours return.
Hallasan: Jeju’s Volcanic Summit
Hallasan (한라산, 1,950m) is the highest point in South Korea and the dominant feature of Jeju Island — a shield volcano whose summit Baengnokdam crater lake is seasonally accessible.
Seongpanak Trail: The longer (9.6km) but less steep approach, through subtropical forest to the summit. The cloud level often obscures the summit crater; the morning windows are the best chance for views.
Eorimok Trail: Shorter (4.7km) but steeper. Does not reach the summit; the viewpoint at Witsere’oreum (1,700m) is accessible and the trail through Hallasan’s unique shrub landscape (gureum cloud forest) is worth doing for the vegetation alone.
Practical note: The summit crater trails close in winter (November–May roughly) due to ice conditions. Eorimok and lower trails remain open year-round.
Korean Hiking Culture
The gear: Korean outdoor retail culture is exceptional. Dongdaemun’s outdoor gear district in Seoul has every technical brand; the Korean domestic brands (Blackyak, K2, Lafuma Korea) produce high-quality gear at prices below the international names.
The food: Koreans bring serious food on trails. Gimbap (rice rolls), fried chicken, makgeolli, dosirak (lunch boxes), and elaborate spreads unpacked at summit rest areas. The trail shelter restaurants (sanjangdo) in national parks serve instant noodles, rice, and makgeolli at prices reflecting their remote location (₩8,000-12,000 per bowl).
Summit makgeolli: Drinking rice wine at the summit is tradition. Most hikers bring their own flask; some peaks have vendors. The combination of altitude, exertion, cold air, and milky fermented rice wine is genuinely excellent.
The timing: Koreans start hiking at dawn. The summit of Bukhansan sees crowds by 9am on weekends; Seoraksan parking lots fill by 7am in autumn peak. Start before sunrise if you want the mountain to yourself.
Trail Difficulty Overview
| Mountain | Best Trail | Difficulty | Hours |
|---|---|---|---|
| Bukhansan | Baegundae summit | Moderate | 4-5 |
| Seoraksan | Ulsanbawi rock | Moderate | 3-4 |
| Seoraksan | Daecheongbong summit | Strenuous | 10-12 |
| Jirisan | Nogodan peak | Moderate | 4-5 |
| Hallasan | Seongpanak summit | Moderate | 8-9 |
Practical Notes
Registration: National parks require trail reservation during peak periods (spring and autumn) through the Korea National Park Service website. Register at least 2 weeks in advance for popular trails on weekends.
Equipment: Proper hiking footwear required above the lower trails. Most Korean hikers wear full technical hiking boots; trail runners are adequate for all except the Jirisan traverse. Trekking poles are used by most Korean hikers and recommended for descent.
Weather: Check the national park forecast website before departure. Mountains create their own weather; the summit conditions can be severe while the trailhead is clear.
