Ask a Korean to name their favorite mountain and the answer is predictable. When Gallup Korea surveyed 1,777 people across the country in March–April 2024, the top pick was Seoraksan at 22%, followed by Hallasan at 20% and Jirisan at 18%. Bukhansan scraped into fourth place at 4%.
But here’s the twist. The same year, the Korea National Park Service tallied actual visitor numbers — and Bukhansan National Park came first, with roughly 7 million people. That’s 17.2% of all 40.65 million national park visits across 22 parks, crammed into a single mountain.
The gap between those two numbers is the whole point of this article. The mountain Koreans daydream about and the mountain their feet actually take them to on a Saturday are different things. For someone living in Seoul, hiking isn’t a trip — it’s something that happens inside their daily radius.
The Short Answer
- The four mountains Seoul locals hike most: Bukhansan · Gwanaksan · Dobongsan · Cheonggyesan. All reachable by subway, all 1–2 hours to the summit one way.
- The deciding factor isn't scenery — it's distance. A 2026 survey found the #1 criterion for choosing a trail is "a mountain close to home" (43.8%).
- If you're new to this, start with Ansan · Achasan · Inwangsan. These are also, by the numbers, the mountains foreign visitors summit most often.
- All 13 mountains are free to enter. But Bukhansan and Dobongsan close entry gates at 5pm (4pm in winter).
Why do Seoul locals insist on hiking inside the city?
Because you step off the subway and start walking. Suraksan Station (Line 7), Exit 1 — the trailhead is right there. Yongmasan Station (Line 7) — five minutes on foot to the mountain entrance. Dobongsan Station (Lines 1 & 7) — about 1km past a row of hiking gear shops to the ranger station.
How much this matters is backed by hard numbers. Embrain Trend Monitor surveyed 1,000 Koreans aged 19–69 in March 2026 and asked them what drives their choice of trail. Here’s how the priorities stacked up:
Scenery comes third. Accessibility and comfort come first. In the same survey, 82.9% agreed that “light trekking has overtaken summit climbing,” and 80.5% said they “pair a hike with a cafe or restaurant after.” The real picture of hiking in Seoul isn’t about conquest — it’s a half-day outing.
The four Seoul mountains locals hike most
Bukhansan · Gwanaksan · Dobongsan · Cheonggyesan. These four are the heavy hitters — the ones with the scale, the name recognition, the buzzing hiking-forum threads, and that unmistakable feel of a “real” mountain.
The personality of each, distilled: Bukhansan is about scale, Gwanaksan about difficulty, Dobongsan about rock ridges, Cheonggyesan about being unfailingly reasonable.
The 'ak-san' rule of thumb
Korean hikers have a saying: if a mountain's name contains the character ak (岳, meaning a rough, rocky peak), it's going to be hard. Seoraksan, Chiaksan, Woraksan — and yes, Gwanaksan. These mountains have more bare rock than soil trails, and they genuinely drain your energy faster. Gwanaksan is counted among the Five Great Peaks (O-ak) of Gyeonggi Province, and its name comes from the rock formations that look like an overturned scholar's hat (gwan). Stick to the beginner routes and it's perfectly tame. Take the Sadang, Yukbong, or Palbong ridges and the mountain lives up to every bit of its reputation.
Dobongsan vs. Cheonggyesan — two mountains, opposite reputations
Dobongsan is a full 100 meters lower than Bukhansan, yet hikers routinely call it harder. The reason: brutal elevation swings and a high ratio of rocky ridge. The Y-Gorge between Podae Ridge and Seonseondae hits a perceived grade of 70 degrees — you’re squeezing through a gap barely wide enough for one person, pulling yourself along on metal bars. The summit of Seonseondae has safety fences and, soberingly, an actual accident-notice board. An alternate route exists; if you’re not confident, take it.
Cheonggyesan, on the other hand, is that rare mountain that tops 600 meters while retaining a reputation for being easygoing. Wonteogol to Maebong is 2.8km, about 1hr 30min. There’s a section nicknamed Kkalttak-gogae (literally “gasping hill” — a steep section that leaves you panting), but it’s fully staircased now. Small landmarks like Dolmunbawi (Stone Gate Rock — three laps around it and your wish comes true, or so they say) break the route into digestible chunks.
All 13 Seoul mountains — one comparison table
🗻 13 Seoul mountains at a glance — elevation, nearest station, one-way time to summit, difficulty (July 2026)
| Mountain | Elevation | Nearest Station | One-Way to Summit | Difficulty | Character |
|---|---|---|---|---|---|
| Bukhansan | Baegundae 836m | Bukhansan-Ui (Ui-Sinseol Line) / Gupabal (Line 3) | ~2hr | Hard | Seoul’s highest, national park |
| Dobongsan | Seonseondae 726m | Dobongsan (Lines 1 & 7) | 1hr 40min–2hr | Hard | Rock ridges, climbing |
| Suraksan | Main Peak 638m | Suraksan / Jangam (Line 7) | 1hr 30min–2hr 30min | Medium-Hard | Train Rock slab |
| Gwanaksan | Yeonjudae 632m | Gwanaksan (Sillim Line) / Seoul Nat’l Univ. (Line 2) | 1hr–2hr 40min | Varies widely | Rocky, diverse routes |
| Cheonggyesan | Maebong 582.5m | Cheonggyesan-ipgu (Shinbundang Line) | ~1hr 30min | Medium | Most manageable “real” hike |
| Bulamsan | ~508m | Danggogae / Sanggye (Line 4) | 1hr–1hr 30min | Medium | Night views, observatory |
| Yongmasan | 348m | Yongmasan (Line 7) | ~50min | Easy-Medium | A notch above Achasan |
| Bugaksan | 342m | Gyeongbokgung (Line 3) + bus | ~1hr | Medium (stairs, all of it) | City wall, history |
| Inwangsan | ~338m | Gyeongbokgung (Line 3) | ~1hr | Easy-Medium | Fortress wall, night views |
| Ansan | ~296m | Dongnimmun (Line 3) | Under 1hr | Easy (barrier-free) | Jarak-gil loop, accessible |
| Achasan | ~296m | Achasan (Line 5) | 40min–1hr | Easy | Sunrise, New Year’s Day |
| Namsan | 270m | Myeong-dong (Line 4) | 20min (North Forest Trail) | Easy | Sightseeing, stroll |
| Eungbongsan | 80–95m | Eungbong (Gyeongui-Jungang Line) | 10–15min | Anyone can do it | Forsythia, night views |
One thing the table makes obvious: elevation and difficulty don’t correlate neatly here. Bugaksan is only 342m, but the trail from Changuimun to Baegakmaru is essentially a 2.5km staircase — your legs will feel every meter. Suraksan sits at a modest 638m, but the mountain is almost entirely granite ridge, making hiking boots and gloves close to mandatory.
Bring gloves
The upper sections of Seoul's major mountains are mostly bare rock. The steel-cable pitch below Bukhansan's Baegundae, the metal bars in Dobongsan's Y-Gorge, the 30-meter slab rope on Suraksan's Train Rock, the vertical face on Gwanaksan's Sadang Ridge — all of them require gripping something with your hands. Seoul's official trail guide for Bukhansan explicitly states hiking boots with good grip and anti-slip gloves are required. A pair of cheap work gloves from any convenience store or Daiso will do the job.
Which mountain should you pick, based on what you want?
Decide on your fitness level and your goal first, then choose the mountain. You’ll have a much better time.
🎯 Goal-based matching — what you want → which mountain → time needed
| What You Want | Recommended Mountain | Round Trip | Why |
|---|---|---|---|
| First hike ever | Ansan, Achasan | 1hr 30min–2hr | Ansan Jarak-gil stays under 9% grade; Achasan is a gentle ridge walk |
| Only have sneakers | Namsan, Eungbongsan, Ansan | 30min–2hr | Fully decked or paved. Hiking boots unnecessary |
| Stroller or wheelchair | Ansan Jarak-gil, Namsan Haneul Forest Trail | 1hr–3hr | Ansan: Korea’s first barrier-free loop (7km); Namsan Haneul: 1.45km, step-free |
| Seoul skyline photos | Inwangsan, Bugaksan, Bulamsan | 2hr–3hr | Inwangsan faces Gyeongbokgung head-on; Bugaksan’s Gokseong section frames the whole mountainscape |
| Night views / after-dark hiking | Inwangsan, Eungbongsan, Bulamsan | 30min–3hr | Inwangsan is open 24hr with lit fortress walls; not a national park, so no curfew |
| Sunrise / New Year’s Day | Achasan, Yongmasan | 1hr 30min–2hr 30min | Achasan Haematji (Sunrise) Plaza; Gwangjin-gu runs an official event every January 1 |
| History and heritage | Bugaksan, Inwangsan, Namsan | 2hr 30min–3hr 30min | Three sections of the Seoul City Wall trail; walk the fortress as it winds around the old capital |
| Spring blooms | Eungbongsan (forsythia), Ansan (cherry blossoms) | 30min–3hr | Eungbongsan Forsythia Festival kicks off Seoul’s flower season in late March |
| A proper mountain day | Bukhansan, Gwanaksan, Dobongsan | 4hr–6hr | Summit is about 2hr one way. Boots, gloves, and water — no compromises |
| Rock-ridge thrills | Suraksan Train Rock, Dobongsan Y-Gorge | 4hr–5hr | Ropes and metal bars. Intermediate or better; if you’re scared of heights, take the bypass |
| Peace and quiet | Ansan, Yongmasan, Bulamsan | 1hr 30min–3hr | No queues even on weekends. Gwanaksan and Bukhansan summits get photo lines |
You'll queue for that summit photo on weekends
Gwanaksan's Taegukgi-bong (Flag Peak) and Yeonjudae, Bukhansan's Baegundae, and Cheonggyesan's Maebong summit stone all develop photo queues between 11am and 3pm on weekends. Gwanak-gu Office has officially designated these hours as peak congestion and ramped up on-site patrols. There's exactly one way around it — start before 7am. National park entry opens at 04:00, so nothing's stopping you from an early start.
Which mountains do foreigners hike in Seoul?
This part comes from mobile data, not guesswork. The Seoul AI Foundation published its 2025 analysis of foreign visitor foot traffic in July 2026. Here are the daily average foreign visitors to four urban Seoul mountains:
What’s interesting is that the mountains people actually summit are different again. The Seoul Tourism Organization’s “10 Summit Challenge” — 500 participants from 62 countries logging 863 completions in 2024 — saw foreign hikers tackle Ansan → Yongmasan → Inwangsan more than any others. Foot traffic data shows Bukhansan draws the biggest crowd, but when it comes to actually reaching the top and checking it off a list, people gravitate toward the shorter, lower peaks.
Three downtown hiking support centers for foreigners
Run by the Seoul Tourism Organization, these centers lend hiking boots, clothes, poles, and crampons — lockers, changing rooms, and showers are free. In the first half of 2025, they saw 44,387 visitors (+25% year-on-year), including 7,343 foreigners. Gear rentals hit 1,648, up 82% from 906 the year before.
- Bukhansan Center — 52 Samyang-ro 173-gil, Gangbuk-gu; 5min walk from Bukhansan-Ui Station. Closed Mondays. Foreigners make up ~60% of visitors
- Bugaksan Center — 88 Samcheong-ro, Jongno-gu; a traditional hanok. Closed Tuesdays
- Gwanaksan Center — B1, Gwanaksan Station (Sillim Line). Closed Wednesdays. Highest total visitors of the three
All open 09:00–18:00. Reservations via Klook.
Rules you need to know before hiking in Seoul
Three things. Entry hours, wildfire season, and the mountains where the “summit” isn’t actually the summit.
1. Designated entry hours — gates close at 5pm
Bukhansan and Dobongsan are national parks, which means entry is only allowed during set hours.
⏰ National park entry hours (applies to Bukhansan & Dobongsan)
| Season | Entry Window |
|---|---|
| Summer (Mar–Nov) | 04:00 – 17:00 |
| Winter (Dec–Feb) | 04:00 – 16:00 |
Times can vary slightly by specific trail, so check the Korea National Park Service website to be safe. Meanwhile, Gwanaksan, Suraksan, Bulamsan, Inwangsan, Bugaksan, Namsan, Ansan, Achasan, Yongmasan, and Eungbongsan are not national parks — these rules don’t apply. Inwangsan is open 24 hours, and Seoul’s official materials confirm it.
2. Wildfire season — no night hiking in spring or fall
Spring February 1–May 15 and fall November 1–December 15 are wildfire-prevention periods. During these windows, night hiking is banned even on open trails, and some trails are closed entirely by district ordinance. Dates shift slightly year to year.
3. Two mountains where you can’t reach the real summit
Cheonggyesan's true summit is Manggyeongdae at 618m, but a military base occupies it. The de facto peak is Maebong, 582.5m.
Gwanaksan can trip you up too. Taegukgi-bong, where the Korean flag flies, is a photo-op magnet — but it's not the summit. Gwanak-gu Office officially states: "The summit is Yeonjudae. Taegukgi-bong is one of several peaks where flags happen to be installed."
What changed in Seoul hiking in 2026
Gwanaksan is drawing a wave of 20- and 30-somethings. A TV documentary in late April 2026 featured the mountain as a place young people visit before a new challenge, and word spread that Gwanaksan has powerful jeong-gi (positive spiritual energy). Job seekers and exam-takers have been showing up in visible numbers; locals say “on weekends you’re queueing just to walk up.”
Namsan got the K-pop Demon Hunters bump. After the Netflix anime used Namsan as its climactic backdrop, the mountain became a pilgrimage route. The newly opened North Forest Trail (2025) cut the walk from Myeong-dong Station to the summit to 20 minutes, and in October 2025, the step-free Haneul Forest Trail (1.45km) opened to the public.
Infrastructure has expanded, too. Dobongsan’s Songchu Valley barrier-free trail was completed in November 2025. Suraksan’s Train Rock got a new viewing deck, rest area, and eight replacement safety ropes courtesy of Uijeongbu City in November 2025. The Inwangsan trail toward Train Rock — damaged in the 2023 wildfire — finished its first phase of repairs in January 2026, handled by Seodaemun-gu.
The post-hike meal is half the experience
In Korean hiking culture, eating after you come down is part of the route, not an afterthought. The Embrain survey backs this up: 80.5% of respondents said they "pair a hike with a cafe or restaurant after."
- Bukhansan (Ui-dong · Gupabal) — tofu hot pot, acorn jelly, mung bean pancake
- Dobongsan Station area — scallion pancake and makgeolli, right where the hiking-gear shop strip is
- Suraksan Station · Madeul Station — gamjatang (pork bone soup), soft tofu stew, knife-cut noodle soup
- Ansan (Dongnimmun Station) — Yeongcheon Market street food. Seoul's official channels recommend this as a classic route
- Inwangsan (Buam-dong · Seochon) — your descent dumps you straight into a cafe alley
How is the Seoul Dullegil different from hiking a mountain?
The Dullegil is a trail that goes around the mountains, not up them — a sideways walk along the foothills. It loops the entire city over 156.5km across 21 sections. Originally launched in 2014 with 8 sections, it was restructured into 21 in 2024, bringing each segment down to roughly 3 hours.
As of July 1, 2026, 101,731 people have completed the full circuit. The annual numbers keep rising: 11,702 finishers in 2024, 12,972 in 2025.
Pick the Dullegil if…
You don't own hiking boots, your knees complain, your group has wildly different fitness levels, or it rained yesterday. There are no rock sections, so the slip risk is low, and you can bail out to a subway station at any point along the way.
So where should you go?
Three sentences:
- If you have a full day and the legs for it: Bukhansan Baegundae. Nothing else in Seoul delivers this kind of payoff — from the summit you see Namsan Tower to Lotte World Tower in a single sweep. Bring boots and gloves. No exceptions.
- If you want a solid half-day mountain: Cheonggyesan Maebong or the Gwanaksan Seoul National University route. Both clock in under 1hr 30min one way, with well-marked trails.
- If you’re here to see Seoul, not to hike: Inwangsan. Follow the old city wall up, and Gyeongbokgung and Gwanghwamun unfold right in front of you. It’s open 24 hours — head up at dusk and watch the city light itself.
Mountains don’t go anywhere. You’re better off hiking a smaller mountain twice than pushing yourself past your limit on the first one.
