Autumn Hiking in Seoul: Climb Bukhansan's Baegundae Like a Local

The short answer: climb Bukhansan in the second half of October, and respect it

If you love a good hike and you're in Seoul this autumn, you don't need a long bus ride to find a real mountain. It's already on the skyline.

My pick is Bukhansan, up to its highest peak, Baegundae, in the second half of October. Go with a guide if it's your first Korean mountain. Go on your own if you're a steady hiker with proper shoes. Either way, please don't treat it as an easy walk. Korean mountains look friendly from the city, and then the granite starts.

Below: what those mountains behind the palace are, when the leaves turn, what the climb asks of you, how to pack like a local, three guided options, and how to spend the hours after you come down.

The mountains behind the palace are Seoul's guardians

Stand in front of Gyeongbokgung Palace and look past the roofs. The rocky mountain right behind it is Bugaksan (342 m), which the Encyclopedia of Korean Culture calls Seoul's main mountain. The palace sits at its foot on purpose: in Joseon-era feng shui (pungsu-jiri), a capital needed a main mountain at its back, with Namsan in front and streams flowing past.

Behind Bugaksan, to the north, rises the bigger range it branches from: Bukhansan. In that same feng shui layout, Bukhansan was the city's guardian mountain, the one that watches over Seoul from the north. Up there, you're standing on the mountain the old capital was built to lean on.

Bukhansan became Korea's 15th national park in 1983. It spans Seoul and Gyeonggi Province, and the Korea National Park Service (KNPS) describes it as a rare natural park inside a city. Its highest peak, Baegundae, stands at 836.5 m. Korea stopped charging admission to its national parks in 2007, so walking in is free. Parking costs money, and a temple can charge for its own grounds.

Why autumn, and when to go this year

Spring and autumn are the best hiking seasons here, and to me autumn wins. The leaves turn, the sky clears, the air is clean, and from the top you can look down over the whole city. For anyone who loves trekking, that view is worth the effort.

Timing matters. The Korea Forest Service's 2026 forecast, released September 22, says colors start in the northern Gangwon mountains in early October and peak across most of the country in late October.

If you want Korea's most famous autumn colors, the same forecast puts Seoraksan at its peak around October 20. It's a beautiful mountain, but from Seoul it's a long bus day, and day tours meet before 7 a.m. Bukhansan is the one you can reach by subway, hike properly, and still be back for dinner.

Don't take it lightly: what the climb to Baegundae asks of you

This is the part I'd tell a friend twice. Treat Bukhansan as an easy hill and it will humble you.

There are two main ways up:

• From the Ui side: KNPS lists 1.9 km one way from Baegun Visitor Center to the summit, about 1 hour 30 minutes. Before that, there's more than 2 km of paved road from the Ui-dong bus terminus to the trail. The Seoul Tourism Organization's trail map starts its Baegundae loop at its hiking center, a 5-minute walk from Bukhansan Ui Station.
• From Bukhansanseong (west): 3.4 km one way, about 2 hours 40 minutes, rated medium by KNPS. Take Line 3 to Gupabal Station, then bus 704 or Yangju 37 to the Bukhansanseong entrance stop.

The last stretch is short but very steep. KNPS says the hardest parts have fixed wire ropes to hold, and the trail narrows as you near the top. It recommends hiking boots and poles, and warns that weekend crowds can slow the summit section a lot. Plan around your fitness and the sunset time, and stay on the marked trails: the closed areas around Baegundae are closed because the fall risk there is high.

Two more rules worth knowing:

• KNPS sets an entry window of 4 a.m. to 5 p.m. on the Baegundae trails from March through November, and it controls access outside those hours. Don't treat 5 p.m. as your plan; build the day around your fitness and the sunset time, as KNPS advises.
• Save the drinks for the bottom. Korea's Natural Parks Act and its decree ban drinking at shelters and on trails and summits the park has designated and signposted. The fine is ₩100,000.

Pack like a local: gimbap, snacks and room for your jacket

Here's how I'd do it, the local way. On the way to the trail, stop at a gimbap shop and buy a few rolls to take with you. I'd pick a real gimbap shop over convenience-store gimbap. My favorite is tuna gimbap (chamchi gimbap), but plain gimbap is fine, and cheese gimbap is tasty too.

Then fill a backpack with gimbap, water, a couple of chocolate bars and some bananas. Leave room for your jacket, because you'll warm up on the climb and want to take it off. Wear trekking shoes or hiking boots if you can.

No boots in your suitcase? The Seoul Hiking Tourism Center (Bukhansan), run by the Seoul Tourism Organization a 5-minute walk from Exit 2 of Bukhansan Ui Station, rents hiking shoes, clothes, gloves, trekking poles and backpacks to foreign visitors, and you can reserve gear online. Its English brochure lists 9 a.m. to 6 p.m., closed Mondays, but says hours may vary, so check the website first.

Guided or on your own: which Bukhansan day fits you

The takeaway: pick by how much of the logistics you want to handle, not just by the summit.

If you want the summit with a guide, the local way: Hiking Adventure Bukhansan Highest Peak & Old Buddhist temples visit (Lunch inc) meets at Exit 2 of Bukhansan Ui Station and takes the shortest route to the top, passing old Buddhist temples and the Bukhansanseong fortress. Lunch is gimbap before the hike, which I like, though you bring your own water. It suits fit first-timers who are fine with the subway.

If you want the summit with no logistics at all: Private Hiking tour to Bukhansan Peak(Baegundae: 836.5m) with Mountain Expert includes hotel pickup and drop-off, a driving guide and a mountain expert, bottled water and a lunch box on the mountain. The route passes Doseonsa Temple on the way up, and the operator puts the climb at 4 to 6 hours depending on your pace. It's private, so the day moves at your speed.

If you want the whole local day at a gentler pace: Private Hiking to Bukhansan & Korean Local Spa(Include Lunch) takes the Gugi-dong trail, which the operator rates as easy and puts at 2 to 4 hours, past Seunggasa Temple. Then come a traditional Korean lunch and a Korean-style spa, with hotel pickup. You won't stand on Baegundae, but you get the full hike, eat, soak rhythm.

After the hike: pajeon, acorn jelly, makgeolli, then a spa

For me, the meal at the bottom is part of the hike. The way I see it, Koreans coming off the mountain head to a restaurant at its foot for pajeon (a green-onion pancake) with makgeolli (milky rice wine), or for a bowl of samgyetang (chicken soup with ginseng). To me, samgyetang is the pricey option. My order is pajeon, dotorimuk (acorn jelly) and makgeolli. With that on the table, I feel like I own the world.

Then take your tired legs to a Korean spa. Hot water after a granite climb is pure bliss. If you'd rather not plan this part yourself, it's exactly what the spa tour above builds in.

The rest of your day, and one thing to do tonight

After the spa, go back to your hotel and rest, or find a cafe, have a coffee and let your appetite come back. For dinner, how about samgyeopsal (grilled pork belly) with soju? If you're new to Korean drinks, Brandon's guide to makgeolli, soju and somaek (opens in a new tab) covers what to order.
