Seoul — City and Peak: Discovering Seoul’s Natural Trails
The side of Seoul most first-time visitors don’t see coming — and shouldn’t miss.
Most people arrive in Seoul with a very specific image in their head. K-dramas, K-pop, street food alleys, neon-lit shopping districts. All of it real, all of it worth your time. But Seoul has another side that most first-time visitors don’t see coming — and it is one of the things that makes this city genuinely unusual among the world’s great capitals.
Seoul is surrounded by mountains. Real ones. And the Han River cuts through the middle of it all. This post is about that side of the city.
01
Seoul’s Natural Setting
Seoul sits in the middle of the Korean Peninsula, along the lower reaches of the Han River. The city covers roughly 605 km², home to around 9.5 million people — with the greater metropolitan area exceeding 25 million, one of the largest urban concentrations on earth.
What makes Seoul’s geography unusual is this: the city is ringed by mountains. To the north, Bukhansan and Dobongsan form a dramatic ridge. To the south, Gwanaksan and Cheonggyesan anchor the other end. At the very centre of the old city, four inner mountains — Naksan, Namsan, Inwangsan, and Bugaksan — encircle the site of the Joseon-era capital, still standing in roughly the same form they always have.
According to Seoul Metropolitan Government records, Seoul is unlike most foreign capital cities in that its outer mountains form a continuous green belt around the city’s edge, while the inner four mountains serve as natural oases within the urban core — all connected by the Han River and its tributaries, the Cheonggyecheon, Jungnangcheon, and Anyangcheon. Mountains and river, city and nature — in Seoul, they are not separated.
02
The River — Han River
514 km — from source at Geomnyongso, Taebaek, Gangwon Province.
Approximately 41 km, running east to west through the city.
Average approximately 1 km, up to approximately 1.2 km near Yeouido.
Average approximately 6–8 m in the Seoul section.
The Han River runs through Seoul from east to west, dividing the city into its northern and southern halves. But for Seoul residents, the Han River is far more than a geographic boundary. It is the city’s living room.
If you have spent any time watching Korean content — dramas, reality shows, vlogs — you have almost certainly seen it already. People spread out on the grass with convenience store food and instant ramen cooked on portable stoves. Couples cycling along the riverside paths. Friends gathered with fried chicken and a view of the bridges at night. That is not a stylised version of Seoul life for the camera. That is just a weekend on the Han River.
Twelve Han River Parks line both banks, with Yeouido, Banpo, Ttukseom, and Mangwon among the most frequented. Cycling paths run continuously along both sides of the river. If the timing works, go at dusk. The view across the water with the city lit behind it is one of Seoul’s quiet rewards.
03
Lakes & Reservoirs
Beyond the Han, the greater Seoul area has a number of lakes and reservoirs worth knowing — each with a distinct character.
Songpa-gu · Jamsil Station, Line 2 / 8
Seokchon Lake
Right in the middle of Jamsil, with Lotte World and Lotte Tower forming the backdrop. Split into East Lake and West Lake, combined perimeter approximately 2.5 km. At its absolute best in spring, when the cherry blossom trees lining the perimeter come into bloom — one of the most visited spots in Seoul during that window. Covered in detail in an earlier post: Seoul in Spring — Cherry Blossom, Seokchon Lake and Coffee.
Goyang-si, Gyeonggi · Daehwa Station, Line 3
Ilsan Lake Park
One of the largest artificial lakes in the metropolitan area, created as part of the Ilsan New Town development. Well-maintained surrounding park, with cycling paths, seasonal flower festivals, and broad open spaces. A solid half-day destination in the northwest of the metro area.
Suwon-si, Gyeonggi · Gwanggyo Jungang Station
Gwanggyo Lake Park
Built within the Gwanggyo New Town development, centred on two connected lakes — Woncheon and Sidae. Well-designed waterfront walkways, and a high density of cafés and restaurants nearby. Popular weekend destination for residents of southern Gyeonggi.
Uijeongbu & Namyangju · Line 1 / Gyeongui–Jungang Line
Uijeongbu & Namyangju Area
The hills north and east of Seoul contain numerous smaller reservoirs, streams, and valley paths. Less destination-specific, more about hiking into the terrain and finding a valley restaurant on the way down — a very local way of spending a Sunday.
04
Mountains — Seoul & the Capital Region
Many visitors to Seoul don’t think of hiking as part of the itinerary. But the conditions are genuinely remarkable — subway to trailhead in under twenty minutes, summit in one to two hours, back in the city for dinner. Very few world capitals offer this.
Seoul’s tourism infrastructure has begun to reflect it: the Seoul Urban Hiking Tourism Center (seoulhiking.or.kr) provides free equipment rental — boots, trousers, shirts — specifically for international visitors who haven’t packed for the trail.
Bukhansan Ui / Dobongsan Station
Bukhansan · 837m
Seoul’s highest peak and its only national park, on the northern boundary with Goyang-si. Main summit Baegundae (836.5m), joined by Insubong (811m) and Mangyeongdae (800m). Ninety-seven trails total. Fastest route to the summit takes approximately ninety minutes.
Dobongsan Station, Line 1 / 7
Dobongsan · 725m
Part of the same national park as Bukhansan, with its own distinct character. Trail begins almost directly from the station — one of the most convenient trailhead access points in the region. Known for sharp granite ridgelines and strong visual drama.
Seoul National University Station, Line 2
Gwanaksan · 629m
The dominant peak south of the Han River, rising behind Seoul National University. Rocky summit with excellent views from Yeonjudae. Accessible from both Seoul and Anyang.
Danggogae Station, Line 4
Suraksan · 640m
Known for unusual rock formations and multiple waterfalls. Particularly popular for valley hiking in summer, when the streams are running.
Cheonggyesan Station, Sinbundang Line
Cheonggyesan · 609m
On Seoul’s southern edge, straddling Seocho-gu, Gwacheon, and Seongnam. The name translates roughly as “clear stream mountain.” Mostly staired, beginner-friendly trails. Wide, satisfying view from the summit ridge, Maebong.
Gyeongbokgung / Dongnimmun Station, Line 3
Inwangsan · 338m
One of Seoul’s four inner mountains, between Jongno-gu and Seodaemun-gu. The mountain depicted in Inwang Jesaekdo, the famous ink painting by Joseon-era master Jeong Seon. The Seoul City Wall runs along the summit. Excellent views across the old city centre.
Gyeongbokgung Station, Line 3
Bugaksan · 342m
Directly behind Gyeongbokgung Palace. Trails were closed for over fifty years from 1968, gradually reopened between 2020 and 2022. Walking the ridge alongside the restored City Wall is one of the better historical walks in Seoul.
Myeongdong / Dongguk University Station
Namsan · 265m
The most accessible mountain in Seoul — N Seoul Tower sits on its summit. Cable car available, also walkable from Myeongdong or Itaewon. Excellent summit view, with a forested approach path that offers genuine respite from the urban density below. The ideal first mountain for visitors.
Seoul National University Station, Line 2
Samseongsan · 481m
Connects to Gwanaksan for a longer combined route. Accessible from both Anyang and southern Seoul.
Gwanggyo Jungang Station, Sinbundang Line
Gwanggyo Mountain · 582m
On the border of Suwon and Yongin in southern Gyeonggi. Dense forest, relatively gentle gradient. Popular for woodland trail walking rather than technical climbing.
Subway to trailhead in under twenty minutes, summit in one to two hours, back in the city for dinner. Very few world capitals offer this.
05
Recommended Courses
Four courses worth planning around — each covered in detail in a dedicated post.
Course 01
Namsan → Myeongdong
Start at the summit of Namsan — cable car up if you prefer, trail down on foot. Descend through the forested slope toward Myeongdong. The transition from mountain quiet to city noise takes about thirty minutes and is one of Seoul’s stranger pleasures. Finish with dinner or street food in Myeongdong.
Course 02
Achasan → Seongsu
Trail up Achasan from the east side of the city, then descend toward Ttukseom and walk into Seongsu. One of Seoul’s most satisfying half-day loops — modest difficulty, followed by one of the city’s best neighbourhoods for coffee and food.
Course 03
Naksan → Hyehwa or Dongdaemun
Naksan is one of Seoul’s four inner mountains — modest at 125m, but its ridge walk along the old City Wall is one of the most rewarding in the city. Start from Naksan Park, follow the wall south, past Ihwa Mural Village and the old Jongno rooftops. Descend toward Hyehwa for university-district cafés, or continue to Dongdaemun for the market and the Zaha Hadid-designed DDP.
Course 04
Namhansanseong · UNESCO Heritage Walk
Namhansanseong Fortress in Gwangju, Gyeonggi Province is a UNESCO World Heritage Site. Fortress walls run along the mountain ridge; the full circuit is around 7.7 km. An ideal day trip from central Seoul — history, nature, and a long lunch in the fortress village at the end.
06
Korean Hiking Culture
In Korea, hiking is not simply exercise. It is a culture — something all generations enjoy, from young couples on a first date to grandparents who have been climbing the same mountain every weekend for decades.
After the hike, you eat. This is non-negotiable. Around the entrance of virtually every major mountain in Seoul, there is a cluster of restaurants — and eating there after a descent is as much a part of the experience as the climb itself.
Acorn Jelly
Dotori-muk
Yes — acorn, as in the things squirrels eat. Technically translated as “jelly,” but the texture is closer to a firm, silky pudding — smooth, dense, mildly nutty. Made from ground acorn starch, served cold and seasoned as a salad-style side (dotori-muk-muchim), or warm in savoury broth with rice (dotori-muk-bap). Found almost only at mountain-entrance restaurants.
Green Onion Pancake
Pajeon
A thick, pan-fried pancake built on a base of green onions — “pa” means green onion. Crispy outside, tender inside, is the mark of a well-made one. Common variations: haemul pajeon with mixed seafood, kimchi-jeon with fermented kimchi, gamja-jeon with grated potato. Pajeon goes with makgeolli — an informal rule that is widely observed.
Ginseng Chicken Soup
Samgyetang
A whole small chicken, stuffed with glutinous rice, ginseng, jujube dates, and garlic, slow-simmered in a clear broth. Rich and deeply savoury. Traditionally eaten in summer as a restorative — a bowl after a hot-weather climb is hard to argue with.
Rice Wine
Makgeolli
An unfiltered Korean brew made from rice and nuruk, a fermentation starter — lightly fizzy, mildly sweet, low in alcohol at around 6%. Long history as the working person’s drink in Korea. Its pairing with pajeon on a mountain-entrance terrace feels entirely right in context.
Before you go, search the mountain name on Google Maps to find the restaurants near the trailhead. The better ones fill up on weekend lunchtimes — worth knowing in advance. Koreans call this the course — the mountain plus the meal after, treated as a single outing. You hike the course. You don’t just hike the mountain.

Practical Notes
A significant number of Seoul’s mountains are granite rock mountains. Wet granite is slippery — bring trail shoes or hiking boots with solid grip. The Seoul Urban Hiking Tourism Center offers free rental if you haven’t packed them.
Temperature at the summit is consistently lower than at the trailhead. Multiple thin layers you can add or remove beat one heavy layer — the standard approach among Korean hikers.
Rocky sections are dangerous without light. Check the sunset time before you start and allow enough margin to be off the trail before dark.
Download the 119 emergency app in advance. Korea’s mountain rescue teams are fast and professional, but accurate location information makes everything easier.
You don’t need to be an experienced hiker to enjoy Seoul’s mountains. If you’ve never hiked before, Namsan or Inwangsan are gentle enough for a first attempt. If you’re dealing with jet lag and want to reset your body clock, an early morning climb — cool air, quiet trails, the city slowly waking up below you — is one of the better remedies. And if you simply want to see Seoul from a different angle, the view from any of these summits is worth the effort.
A city seen from the ground is one thing. Seen from the ridge above it, it becomes something else entirely.
