Seoraksan Autumn Foliage Guide — Peak Timing, Trails by Difficulty, and Beating the Crowds

Seoraksan’s autumn colours usually peak in mid-October or just after, roughly October 15 to 25. Every autumn our phone gets busy with the same questions: “When are the leaves best?” “Is it already too late to go now?”

I was born and raised in Sokcho and have looked at Seoraksan all my life. Every year we watch it change colour from our third-floor windows. Here is what we have learned from that view.

When exactly does Seoraksan peak?

Seoraksan’s colours start in late September or early October and peak two to three weeks later, in mid-October or just after. Foliage has two milestones, first foliage and peak:

• First foliage: when about 20% of the mountain has turned. On Seoraksan this usually starts in late September to early October. It is one of the earliest in Korea.
• Peak: when more than 80% has turned. That comes roughly two to three weeks after first foliage, so Seoraksan generally peaks around October 15 to 25.

Seoraksan is tall, so colour moves from the top down. Daecheongbong summit turns first, then the mid-slopes, and finally the low ground near the park entrance.

So in early October the peaks look glorious while the base is still green. By late October the base is beautiful but the upper slopes have already dropped their leaves.

Around mid-October, top and bottom look good at the same time. That is why the crowds peak then.

It shifts a little every year

A long, hot summer pushes the colours back about a week. A cool September with big day-night temperature swings pulls them forward. Recent years have trended later as summers stretch longer.

The reliable move is to check three or four days before you travel:

• Korea Meteorological Administration (weather.go.kr) foliage observations
• Korea Forest Service (National Institute of Forest Science) foliage forecast map
• Seoraksan National Park’s official site for live photos and notices
• Search #설악산단풍 on Instagram or Naver sorted by newest. You will see photos from the trail a day or two ahead of the official reports.

Call us and we will tell you what we can see. We look at that mountain every day.

Trails by fitness level: you don’t need hiking boots

People assume you must be a serious hiker to see Seoraksan’s colours. Not necessarily. Several routes are fine in ordinary trainers.

1. Very easy: Sogongwon stroll (30 min to 1 hour, ★☆☆)

Flat path from the Seorakdong Sogongwon entrance past Sinheungsa Temple to the Great Unification Buddha. Pushchairs roll fine and older visitors manage comfortably.

The giant Buddha surrounded by autumn colour, with the Ulsanbawi ridgeline behind it, is far more impressive than it sounds. Ideal if you want the colours without the climb.

2. Our top pick: Biryong Falls & Towangseong Falls viewpoint (about 3 hours round trip, ★★☆)

This is what we recommend most in autumn. Sogongwon → Yukdam Falls → Biryong Falls → Towangseong Falls viewpoint is 2.8 km one way; allow about three hours round trip.

The path follows the stream, so you get water sounds with your foliage, and the colours reflected on the water photograph beautifully. The first stretch is gentle, but the last 400 m from Biryong Falls to the viewpoint is close to 900 steep steps (distances and step counts are from telltrip.com trail guides, checked October 2026). If you walk regularly you can manage it at an easy pace. The steps get slippery when wet, so take them slowly.

3. Worth the effort: Ulsanbawi Rock (4 hours round trip, ★★★)

Past the Rocking Rock, a long run of steep stairs climbs to the 873 m summit of Ulsanbawi. Those stairs are no joke, and you will stop to breathe several times.

But from the top you see the Seoraksan ridges, Sokcho city, and the East Sea all at once. It really does feel like floating above the foliage.

Bring trekking poles if your knees are weak; the descent is harder than the climb.

4. The easy option: the upper-station deck and Gwongeumseong by cable car (1.5 hours excluding the queue, ★☆☆)

If walking is difficult, or you have small children or elderly parents, the cable car is the answer. Five minutes gets you up to mid-mountain to look down over the colours. There is a viewing deck right at the upper station; the Gwongeumseong fortress site is another 15 to 20 minutes up a rocky path. If walking is hard, you can stop at the deck and ride back down. Fares, hours and queue tactics are in our separate Seoraksan cable car guide.

5. A bit further: Jujeongol Valley (3 hours round trip, ★★☆)

This one is on the Osaek side in Yangyang. From Sokcho it is easiest by car, and the drive takes longer than to the other trails. Mostly boardwalk, so it is easy walking, yet the valley scenery is dramatic. A good alternative when Sogongwon is overrun.

How do you avoid the Seoraksan foliage crowds?

To avoid the crowds, go on a weekday; at weekends, arrive before 7 a.m. or after 3 p.m. Mid-October weekends at Seoraksan are packed. The Sogongwon car park starts filling by 8 a.m. and cable car waits can hit two hours.

After years of watching this, here is what works.

One: go on a weekday. If you can manage it, nothing else comes close. From Tuesday to Thursday it is far quieter than at weekends.

Two: if it must be a weekend, arrive before 7 a.m., 8 at the latest. After 9 you start queueing just to enter the car park.

Three: after 3 p.m. works too. Crowds thin out sharply late in the day. Low autumn light also makes the colours look richer. Just pick a short route, because darkness comes early.

Four: go the weekend before peak. Once word gets around that it is peak week, people come from all over the country. The weekend before is already lovely, with far fewer people and plenty of colour.

Getting there and parking

• From central Sokcho to Seorakdong Sogongwon is 20–25 minutes by car. About the same from our restaurant.
• By bus, take city bus 7 or 7-1 from Sokcho Intercity Bus Terminal or near Sokcho Beach to Seorakdong Sogongwon. Buses are infrequent, so check the timetable first.
• Parking is at the Sogongwon car park, which frequently fills on autumn weekends. When full you are directed to overflow car parks further down, then walk or take a shuttle. Shuttle arrangements can change from year to year, so follow the signs on site.
• There is no national park entrance fee. You do pay for parking, though, and the cable car has its own fare (per national park visitor information, checked October 2026).

What to bring

October on the mountain is colder than you expect; it is noticeably cooler up top than in Sokcho town. Every year we meet people who set out in short sleeves and shivered at the top.

• A light windbreaker: packs small and helps a lot with staying warm
• Water and a snack: there are almost no shops on the trails
• Comfortable shoes: cushioned trainers are fine; boots not required
• A power bank: you will take many photos and cold drains batteries fast
• Hat and sunglasses: autumn sun is sharper than it looks

After the hike: where to eat

After three or four hours on the mountain your legs ache and you are properly hungry. Many people reach for something hot, but we would suggest a bowl of ice-cold mulhoe instead: sliced raw fish in a tangy, slushy iced broth.

That first sip of tangy chilled broth after a sweaty descent drops your body temperature and wakes you right up. The tiredness rinses away. Finish by stirring rice into what’s left of the broth and you leave genuinely full.

We are 20–25 minutes by car from Seorakdong, and we are right in front of Sokcho Beach, so you can look at the sea before heading home. Autumn sea has a quieter, deeper colour than summer.

We have a large third-floor hall for hiking groups. If there are many of you, please call ahead. Tables fill up fast in foliage season.

From our Sky Stairs rooftop viewpoint you can see the sea and the Sokcho Eye Ferris wheel in one frame. Go up for a photo after your meal.

Travel safely, and when you come down, stop by for a bowl of cold mulhoe.
