Korea in Autumn 2026: The Best Places to See Fall Foliage
There is a short time every year when Korea seems to change its colours overnight.
The mountains turn red and gold, the palace gardens look even more beautiful and even an ordinary walk down a city street can feel a little special. If you have ever seen photos of Korea in autumn and wondered if the colours really look that good in person, I can tell you, they do!
Autumn would be one of my favourite times to think about visiting Korea. The weather is comfortable, the summer heat has finally disappeared and there is something lovely about being outside without having to rush from one place to another.
The only tricky part is TIMING.
The leaves do not all change at once. Autumn starts in the northern mountains and slowly moves south, so the best time to see the colours depends on where you are going.
That is actually part of the fun! If Seoraksan is already past its best, Seoul might just be reaching peak colour. And when Seoul begins to lose its leaves, places further south, including Jeju, can still have plenty of autumn left to enjoy.
So, if you are planning a Korea trip this autumn, here are the places I would keep on your list!
When Does Autumn Foliage Season Happen in Korea?
In general, Korea's autumn foliage season runs through October and November.
The first colours usually appear in the higher, northern mountain areas before gradually moving south. For 2026, the forecast gives us a useful idea of when different destinations should begin changing and when they are expected to reach their peak.
Destination | First foliage | Expected peak |
Seoraksan | October 3 | October 25 |
Chiaksan | October 10 | October 31 |
Bukhansan | October 23 | November 4 |
Nami Island | October 24 | November 8 |
Woraksan | October 25 | November 5 |
Bulguksa Temple, Gyeongju | October 25 | November 10 |
Palgongsan | October 26 | November 12 |
Jirisan | October 28 | November 5 |
Hallasan, Jeju | October 31 | November 13 |
Of course, these dates are a forecast rather than a guarantee. Weather can make the leaves change a little earlier or later.
If you simply want the easiest general window, late October to early November is a good time to plan around. But if you have a particular destination in mind, it's worth checking its expected dates before booking your trip.
1. Seoraksan: Where Autumn Begins
If you want that classic Korean autumn feeling, mountains, colourful forests and dramatic scenery, Seoraksan is probably the place that comes to mind first.
This is where autumn begins earliest on the 2026 forecast, with the first foliage expected around October 3 and peak colour around October 25.
And Seoraksan is beautiful even without the leaves. Add red and golden trees to the rocky peaks and forested valleys, though, and it becomes something else entirely.
You do not have to be an experienced hiker to enjoy it. There are trails at different levels, and the cable car gives you a chance to see the scenery without committing to a long mountain hike.
If you can, go on a weekday and start early. The most popular areas can get busy once the day gets going, especially during peak foliage.
My tip: Don't worry about seeing every trail. Pick one area, slow down and actually look around. The views are the reason you're there.
2. Seoul: You Don't Have to Leave the City
One of the nicest things about autumn in Korea is that you don't need to travel to a national park to enjoy it.
Seoul has plenty of beautiful places to see the changing leaves, from Gyeongbokgung Palace and Namsan to Seoul Forest and Olympic Park.
The expected first foliage around Bukhansan is October 23, with peak colour around November 4, so early November can be a particularly lovely time to explore Seoul.
And honestly, some of the best autumn moments would not involve sightseeing at all!
It might be walking past a row of golden ginkgo trees with a coffee in your hand. Or wandering around a palace when the leaves have started covering the ground. Or taking the long way back to your hotel because the street looks too pretty to leave.
Namsan is especially nice if you want an easy autumn walk without making a whole day of it.
My tip: Leave an afternoon free in your Seoul itinerary. Grab something warm to drink and go for a slow walk. You don't always need a plan.
3. Nami Island: For a Slower Kind of Autumn
Nami Island is famous for its connection to Winter Sonata, but you don't have to know the drama to understand why people love coming here.
The tree-lined paths are made for autumn.
The 2026 forecast places the first foliage around October 24, with peak colour around November 8. That makes Nami Island a particularly nice option if you're visiting Seoul around the beginning of November.
It is also an easy day trip, which makes it convenient if you do not want to change hotels or spend several days travelling around the country.
The best way to experience Nami Island, in my opinion, is not to rush through it trying to see everything.
Walk. Stop for a while. Take photos when you feel like it. Sit somewhere and watch people go by.
Sometimes autumn is best enjoyed when you are not trying too hard to enjoy it.
My tip: If you can, visit on a weekday. You will have a much easier time finding those quieter moments.
4. Gyeongju: When Autumn Meets History
Gyeongju is already one of the most atmospheric places to visit in Korea. In autumn, it gets even better.
As the former capital of the Silla Kingdom, the city is filled with ancient temples, tombs and historic sites. It often feels like you are walking through a very open-air museum and then you notice the autumn trees framing everything.
At Bulguksa Temple, the first foliage is expected around October 25, with peak colour around November 10.
The combination of old architecture and red and golden leaves is hard to beat.
Gyeongju is also a place where rushing from one attraction to the next is not recommended. Give yourself time to wander, rent a bicycle if you would like, stop for coffee and enjoy the quieter side of the city.
If you can spare it, a day and a half or two days gives you much more room to enjoy Gyeongju properly.
5. Jirisan and Hallasan: Save Some Autumn for Later
If you are travelling later in the season, don't worry, you haven ot missed everything.
Autumn moves south, which means places like Jirisan and Hallasan come into their own later.
Jirisan is expected to see its first foliage around October 28, reaching peak colour around November 5. It is a great choice if you want a more natural, mountain-focused experience away from the busiest city attractions.
Then there is Hallasan on Jeju Island, where the first foliage is expected around October 31 and peak colour around November 13.
What I love about Jeju is that you can combine your autumn trip with everything else the island offers. Spend part of the day around the mountain, then head towards the coast, find a café and warm up with a drink while looking out at the sea.
November can also feel a little quieter on Jeju, which is another reason to consider travelling later in the season.
If you are hiking Hallasan, make sure you check the trail opening and cutoff times before setting out. Mountain conditions and access can be very different from a casual city walk.
One More Place Worth Knowing: Naejangsan
Naejangsan is not on the map we are using, but I would not leave it out of an autumn conversation.
It is one of those places that comes up again and again when people talk about beautiful fall foliage in Korea, particularly for its colourful maple trees.
The famous maple-lined paths can look almost unreal when the leaves turn deep red. Its peak is expected around November 11, making it another good option for travellers visiting in early to mid-November.
If you go, an early start is worth considering. The quieter morning atmosphere can make a big difference.
You Don't Have to Be a Hiker to Enjoy Autumn in Korea
This is probably worth saying because when you search for Korean autumn foliage, you will see a lot of mountain trails.
But you really do not have to hike.
Seoul alone has more than 100 designated autumn foliage walking routes and many beautiful spots are completely accessible to casual walkers.
You can see autumn from a palace courtyard, beside a river, in a city park, along a quiet neighbourhood street or simply on your walk to dinner.
So don't feel as though you are missing out because you are not planning a mountain trek.
A Few Things to Keep in Mind
Foliage dates can change. Weather plays a big part, so use the forecast as a guide rather than an exact appointment.
Popular places get busy. If you want a quieter experience, weekdays and early mornings are your friends.
Pack layers. Autumn days can be comfortable while mornings and evenings feel surprisingly chilly, particularly in the mountains.
Don't pack your itinerary too tightly. This is one season where leaving some breathing room can make your trip better.
Why Autumn in Korea Is Worth Experiencing
There are plenty of reasons to visit Korea in autumn, but I think the biggest one is simply the atmosphere.
The mountains become red and gold. Palace courtyards seem softer. Seoul's ginkgo trees turn bright yellow, and suddenly even familiar parts of the city feel different.
And perhaps that is what makes autumn so lovely here.
You don't always have to go looking for it.
It finds you.
Come for the food. Stay for the cafés. Explore the palaces, the mountains and the small, quiet streets. And somewhere along the way, take an afternoon to simply walk beneath the autumn leaves.
You might find that it becomes one of your favourite memories of Korea.
