South Korea has 22 national parks covering 6.7% of the country's total land area, and its mountain trails are among the most technically maintained in Asia — yet they remain largely unknown outside the region. From Hallasan's 1,950 m summit on Jeju Island to the granite spires of Seoraksan's Ulsanbawi Rock, South Korea offers serious hiking within 90 minutes of Seoul.
Why South Korea Belongs on Every Hiker's List
Korean hiking culture runs deep. You'll see locals in full technical kit — gaiters, trekking poles, compression tights — on trails that most Western hikers would treat as casual walks. The Korea National Park Service (KNPS) maintains its trails to an exceptional standard, with rope-assisted sections, metal staircases bolted into granite faces and reliable hut infrastructure on multi-day routes. Trail signage is bilingual (Korean and English) on all major routes. The permit system operates entirely online via the KNPS website, opening one month in advance for summit trails — set a calendar reminder or you'll miss your window.
Seoraksan National Park: Granite Towers in Eastern Korea
Seoraksan is the most dramatic mountain landscape in Korea. The highest peak on the Taebaek Range reaches 1,708 m, and the surrounding granite spires, ridgelines and valley waterfalls rival anything in the Alps for visual impact — at a fraction of the cost. The Ulsanbawi Rock circuit covers 6.4 km with 873 m of elevation gain and includes a 808-step metal staircase bolted onto the north face of the rock formation. Allow 4–5 hours. For multi-day hikers, the Dinosaur Ridge traverse from Heunsadeam to Biseondae is a technical scramble on exposed rock that requires solid footwear — the Salomon X Ultra 4 Mid GTX handles Seoraksan's angular granite and occasional wet rock sections reliably. The trail to Daecheongbong summit (1,708 m) requires a KNPS online permit booked one month ahead.
Getting to Seoraksan
- Fly into Incheon (ICN) or Gimpo (GMP) airports in Seoul
- KTX bullet train to Gangneung: 90 minutes, around ₩27,000 ($20)
- Bus or taxi from Gangneung to Sokcho (the gateway town): 40 minutes
- Cable car to Gwongeumseong Fortress: optional shortcut saving 300 m of gain
Hallasan: Summiting South Korea's Highest Peak
Hallasan on Jeju Island sits at 1,950 m — the highest peak in South Korea and a UNESCO World Heritage volcano. Two main trails reach the summit: the Seongpanak trail (9.6 km one-way, 1,050 m gain, forest path) and the Gwaneumsa trail (8.7 km one-way, more dramatic canyon scenery). Both require a summit permit booked through the Korea National Park website. The summit closes at 12:00 noon via Seongpanak to ensure all hikers descend before dark — an early start by 7:00 AM is mandatory. Water on the trail is limited to two shelter points; carry at least 2 L from the trailhead. Direct flights from Seoul to Jeju take 55 minutes and cost $30–70 depending on booking lead time.
The Baekdu-daegan Ridge Trail: Korea's Spine
The Baekdu-daegan is a 735 km mountain ridge that forms the geographical backbone of the Korean peninsula. Thru-hiking the entire route takes 40–50 days; most hikers tackle it in multi-day sections. The Jirisan section is the most popular — Jirisan at 1,915 m is the highest peak on the Korean mainland and the section from Nogodan to Cheonwangbong (36 km, 3–4 days) is considered the premier multi-day backpacking route in the country. Shelters (sanjang) are spaced 7–12 km apart, cost ₩10,000–15,000 ($7–11) per night, and require advance reservation through the KNPS booking portal. A Black Diamond Speed 40 sits at the right capacity for a 3-night Jirisan traverse with shelter use — you won't need to carry a tent or cooking system, keeping base weight under 7 kg. Navigation on the ridge is straightforward in summer but winter conditions can be severe; the Garmin GPSMAP 67 loaded with Korean topo maps provides reliable off-grid navigation.

The Jeju Olle Trail: Coastal Walking at Its Best
The Jeju Olle is a 437 km coastal walking route divided into 26 sections averaging 14 km each. No permits are required and the trail is open year-round — the mild oceanic climate on Jeju means even January daytime temperatures hover around 5–8°C. Sections 7 and 10 are the visual highlights, tracking clifftop paths above black lava sea stacks. The Olle App (free download) provides offline maps for all 26 sections. Korean tourism data shows October and November as peak Jeju visitor months due to autumn foliage on the slopes of Hallasan visible from the coastal path. Rain protection is essential — the Patagonia Torrentshell 3L handles Korea's heavy spring and autumn rain events reliably.
Planning Your Korea Hiking Trip
Direct flights from major European hubs (London, Amsterdam, Frankfurt) to Incheon Airport run 11–13 hours. Budget airlines offer Seoul–Jeju connections for as little as $25 booked three weeks ahead. The best overall hiking season is May for azalea blooms and October for autumn foliage — Korea tourism statistics confirm these as the peak visitor months, so book accommodation and permits early. The KNPS permit portal at english.knps.or.kr opens exactly one month before the hiking date at midnight Korean Standard Time. For navigating between parks and cities, the T-Money transit card (available at Incheon Airport) covers all buses, trains and subways from $1.30 per journey. For further trail variety across Asia, compare Korea to the routes covered in our Dolomites hiking guide. Pack for variable weather — our ultralight rain jacket guide and best hiking boots guide cover the options suited to Korean trail conditions. If digital navigation matters to you, the best navigation apps guide includes apps with Korean map support.
Frequently Asked Questions
Do I need a guide to hike in South Korea's national parks?
Most Korean national park trails are self-guided — no compulsory guide requirement. You do need an online permit for designated summit trails (Hallasan summit, Daecheongbong on Seoraksan). Trail signage is bilingual, and the Naver Maps app provides reliable offline navigation across Korean trails with English-language search.
What is the best time of year to hike in South Korea?
May and October are the two premium months. May brings azalea blooms on high ridges and stable temperatures of 15–22°C at valley level. October delivers the famous Korean autumn foliage (danpung), particularly on Seoraksan and Jirisan. Avoid July and August — monsoon season brings heavy, persistent rain across most of the country.
How difficult are Korean hiking trails compared to European ones?
Korean trails tend to be shorter but steeper than equivalent European routes — elevation gain per kilometre is often 150–200 m, compared to 80–120 m on typical Alpine paths. The terrain is predominantly granite and rock, requiring footwear with sticky rubber soles. The KNPS difficulty ratings (Easy / Moderate / Difficult) are broadly reliable but use a Korean reference frame — a Korean "moderate" trail often matches a European "hard."
Can I hike the Baekdu-daegan Ridge Trail as a solo foreigner?
Yes. The ridge trail is open to independent foreign hikers without a guide. The main challenges are shelter reservations (all online, with some Korean-language navigation required) and route-finding on less-maintained sections. Download the Baekdu-daegan Trail App for offline maps or carry printed 1:25,000 topo maps from the National Geographic Information Institute of Korea.
What currency and costs should I expect for hiking in Korea?
The South Korean Won (KRW) is the currency. National park entry is free at most parks; parking costs ₩4,000–5,000 ($3–4). Shelter accommodation runs ₩10,000–15,000 ($7–11) per night. A full day of food and transport outside Seoul costs $25–40. Credit cards are accepted almost everywhere, including small trailhead shops.
