Korea in October: Weather, Foliage, Things to Do & Travel Tips

October is probably one of the easiest months to love in Korea. The sticky summer weather is finally gone, mornings and evenings feel cool, and the streets start getting that unmistakable autumn feel. You’ll see leaves changing around the city, mountains turning red and gold, and, in places like Jeju, fields of silver grass and pink muhly. It’s also still comfortable enough to spend most of the day outside without worrying about the heat.

If you’re coming to Korea in October, don’t plan your trip around foliage alone. This is a great month for palace walks, easy hikes, weekend markets, seasonal food, festivals, and day trips out of Seoul. Here’s what to expect in October, including the weather, where to catch the best autumn scenery, what to wear, and a few local tips that can make your trip a lot easier.

Korea Weather in October

Bài viết do Korea Travel Guide 🇰🇷 (@ivisitkorea) chia sẻ

October weather in Korea is generally cool, dry, and comfortable, but there is quite a noticeable difference between the beginning and end of the month.

In Seoul, average October temperatures are around 20°C during the day and 11°C at night. Busan is warmer, with average highs around 23°C and lows around 15°C. Jeju is also relatively mild, with temperatures generally staying around the low 20s during the day.

These are averages, though, so don’t treat them as a daily forecast. A sunny October afternoon can still feel surprisingly warm, while a cloudy or windy evening can feel much colder than the numbers suggest.

October Korea Itinerary Ideas

Not sure how to put your October trip together? Here are two sample itineraries created with our Korea Trip Planner, with one focused on Seoul and another on Jeju. They’re a good starting point if you want to see what a few days in Korea could look like without planning everything from scratch.

The best part is that you don’t have to follow them exactly. You can edit, save, and create your own itinerary for free, while getting local insights to help you choose places, plan your days, and make the most of your time in Korea. Just adjust the itinerary based on your travel dates, interests, and pace.

Best places to see Autumn foliage and scenery in Korea

Seoraksan Mt

If foliage is the main reason you’re coming to Korea, Seoraksan should be near the top of the list. The scenery here is completely different from seeing a few colorful trees in Seoul. You get entire mountainsides changing color, dramatic rock formations, valleys, streams, and temples.

The downside is that Seoraksan gets very busy during peak foliage, especially on weekends. If you’re going independently, starting early is worth it. If you don’t want to deal with figuring out transportation and hiking routes yourself, an organized autumn day tour can also make sense.

Nami Island

This island is popular for a reason. Its long tree-lined roads look particularly pretty in autumn, especially when the ginkgo and maple trees start changing.

But this is also one of those places where Instagram photos don’t really show how crowded it can get. If you visit during peak foliage, expect plenty of tour groups and people stopping for photos along the most famous paths. For a more relaxed experience, go on a weekday and get there early.

Seoul

You don’t have to leave Seoul to experience autumn. In fact, if your trip is short, I wouldn’t spend an entire day traveling somewhere far away just to see leaves when there are plenty of beautiful spots inside the city.

Good places include:

• Namsan Park
• Seoul Forest
• Seodaemun Independence Park
• Samcheong-ro
• Haneul Park
• Bukhansan
• Gyeongbokgung
• Changdeokgung
• Deoksugung Stone Wall Road

One of my favorite things about autumn in Seoul is that the city doesn’t stop being a city just because the leaves change. You can see colorful trees against palace roofs, apartment buildings, cafés, and busy streets. It feels much more like everyday Seoul than a dedicated tourist attraction

Best Experiences in Seoul!

Hwadam Botanic Garden

This is a local favorite for autumn foliage. Hwadam Forest is basically a giant colorful garden in fall, with maple trees, quiet trails, little ponds, and plenty of pretty spots to stop for photos. The monorail is worth trying too, it takes you through the forest and gives you a great view without all the uphill walking.

Autumn reservations can sell out, so don’t treat it like a spontaneous stop if it’s high on your list.

Naejangsan

If you have more time and really love autumn scenery, Naejangsan is worth considering. It’s famous for vivid maple foliage, mountain scenery, and temples. The scenery can be spectacular, but getting there takes more effort than visiting a Seoul park or Nami Island. This is one I’d save for travelers who have already seen Seoul and want to make autumn foliage a major part of their Korea trip.

Best Places to See Pink Muhly and Silver Grass in Korea in Autumn

Autumn in Korea isn’t just about red maple leaves. If you want something a little softer and more dreamy, look for pink muhly and silver grass. They usually start appearing from September and look especially beautiful in October, when the fields are full and the weather is cool enough for a comfortable walk.

Gyeongju Cheomseongdae Observatory

One of the prettiest places to see pink muhly is right in the middle of historic Gyeongju. The pink fields around Cheomseongdae create a lovely contrast with the ancient observatory, and you can easily combine it with nearby Daereungwon, Woljeonggyo Bridge, and other historic sites. It’s free and open year-round, so you don’t need to make a separate trip just for the flowers.

Haneul Park, Seoul

If you’re staying in Seoul, you don’t need to travel out of the city. Haneul Park is one of the easiest places to catch both pink muhly and silver grass in autumn. The wide open fields are especially beautiful in the late afternoon, although this is also when the park gets busy. Haneul Park’s annual Silver Grass Festival is another reason October can be a particularly lively time to visit.

Gochang Blue Farm

• Address: 469-1 Yejeon-ri, Gongeum-myeon, Gochang-gun, Jeonbuk State, South Korea

For a much larger pink muhly field, head to Gochang in Jeollabuk-do. The farm turns pink during the autumn blooming season, with walking paths and photo spots spread across the field. It’s a better option if you want that “pink as far as you can see” kind of scenery rather than just a small flower garden.

Saebyeol Oreum, Jeju

Bài viết do Jeju Tourism Organization (@visitjeju.en) chia sẻ

This is one of the classic places to see silver grass in Jeju. In autumn, the slopes of Saebyeol Oreum are covered with tall silver grass that moves with the wind, creating the kind of scenery that makes you want to slow down and just walk around. It’s also relatively easy to reach the top compared with some of Jeju’s other oreum.

Sangumburi Crater, Jeju

Another great option if you’re already exploring Jeju. Silver grass grows across the volcanic landscape around Sangumburi, so you get more than just a field of flowers, the combination of grass, crater scenery, and open sky is what makes it special.

Suncheonman National Garden

If you’re heading to Suncheon, Suncheonman National Garden is a lovely place to slow down and enjoy Korea’s autumn scenery without the crowds and pace of Seoul. The garden has a mix of seasonal flowers, landscaped gardens, and wide open areas where you can see silver grass and other autumn plants.

It’s especially nice in the late afternoon, when the soft light makes the grass look even more golden. After exploring the garden, you can also continue to Suncheonman Wetland, where the vast reed fields create one of the most iconic autumn landscapes in southern Korea.

Festivals to Check Out in Korea in October 2026

October is a surprisingly fun month for festivals in Korea. Beyond the autumn foliage, you’ll find everything from traditional mask dances and lanterns to huge EDM and film festivals. If you’re already traveling around Korea, it’s worth checking what’s happening near your route, you might be able to fit a festival into your itinerary without making a special trip.

Andong International Maskdance Festival

• September 24 – October 4, 2026 | Andong

The 30th Andong International Maskdance Festival is a great pick if you want to see a more traditional side of Korea. Held across Mask Dance Park, Andong’s old downtown, Andong Station, and Hahoe Folk Village, the festival brings together Korean and international mask dance performances.

One of the highlights is Hahoe Byeolsingut Talnori, a traditional mask dance drama from Andong’s Hahoe Village. You can also join mask-making activities, watch street parades, see international performances, and take part in the lively Daedong Nanjang mass dance. General admission is free, although some special programs may charge a fee.

EDC Korea 2026

• October 3 – 4, 2026 | INSPIRE Entertainment Resort, Incheon

If traditional performances aren’t really your thing, there’s always EDC Korea. This huge electronic dance music festival brings a completely different energy to the October calendar, with large-scale stages, DJs, light shows, and festival crowds taking over INSPIRE Entertainment Resort in Incheon.

It’s an easy one to consider if you’re staying in Seoul since Incheon is close enough for a day trip, although you’ll want to check transportation and event timings before going.

Busan International Rock Festival

• October 2 – 4, 2026 | Samnak Ecological Park, Busan

Prefer live music? The Busan International Rock Festival is another October option, bringing rock and alternative acts to Samnak Ecological Park.

The outdoor setting makes it a particularly nice match for October weather, so if you’re already planning a Busan trip around early October, check the lineup before deciding whether to add it to your plans.

Yeongdong Nangye Korean Traditional Music Festival

• October 15 – 18, 2026 | Yeongdong, Chungcheongbuk-do

For something more traditional, head to Yeongdong for the Yeongdong Nangye Korean Traditional Music Festival. The festival celebrates gugak, Korea’s traditional music, alongside local food and wine-related events.

It’s a good option for travelers who want to see something outside the usual Seoul-Busan route and experience a smaller local festival.

Jinju Namgang Yudeung Festival

• October 3 – 18, 2026 | Jinju

This is one of the most visually impressive festivals in October. The Jinju Namgang Yudeung Festival fills the Namgang River and surrounding area with thousands of colorful lanterns, with the main displays lighting up after sunset.

The festival takes place around Jinjuseong Fortress and the Namgang River, and its history goes back to the lantern tradition associated with the 1592 Siege of Jinju. Along with floating and wishing lanterns, you can see large-scale light installations, performances, and other nighttime events.

If you enjoy taking photos, go after 6 PM when the lanterns are lit. The atmosphere is completely different once the river starts glowing.

Gimcheon Gimbap Festival

• October 23- 25, 2026 | Jikji Culture Park, Gimcheon

For something a little more unusual, there’s the Gimcheon Gimbap Festival. As the name suggests, this local festival is all about one of Korea’s favorite everyday foods: gimbap.

It’s a fun choice if you’re interested in Korean food culture beyond the usual tourist food spots, with gimbap-related activities and local events taking place around Jikji Culture Park.

What to Pack for Korea in October

A practical October packing list:

• Light jacket
• Sweater or cardigan
• Long-sleeve tops
• A few T-shirts
• Comfortable walking shoes
• Small umbrella
• Portable charger
• Power adapter
• Lip balm
• Moisturizer
• Sunglasses
• Small day bag

If you’re going to Jeju, Seoraksan, or other outdoor destinations, add a warmer layer and shoes with decent grip. And don’t worry too much about packing every possible type of clothing. Korea is full of affordable clothing stores, so if the weather suddenly gets colder, buying an extra sweater here isn’t exactly difficult.

Public Holidays in Korea in October 2026

October has several important public holidays in Korea, so it’s worth checking the calendar before planning day trips or intercity travel. National Foundation Day falls on October 3, but in 2026 the observed holiday is Monday, October 5. Hangeul Day is on October 9 (Friday), giving locals another long weekend.

If you’re traveling around October 3 – 5 or October 9, expect more domestic travelers, especially at popular autumn destinations. KTX trains, intercity buses, hotels, and popular day tours can fill up faster than usual.

It’s not a reason to avoid these dates, though. You just need to plan a little earlier. Book intercity transportation and accommodation ahead of time, and if possible, visit famous foliage spots on weekdays rather than during the holiday weekends.

One more thing: public holidays don’t mean that everything closes in Korea. Most major tourist attractions, shopping areas, cafés, and restaurants remain open, although individual businesses may have different hours.

Must-Try Autumn Foods in Korea

Autumn in Korea is also a pretty good season for food. As the weather cools down, markets and street stalls start filling up with seasonal ingredients, and you’ll see plenty of chestnuts, sweet potatoes, persimmons, pears, and fall seafood. Some are simple snacks you can grab while walking around, while others are worth ordering at a restaurant.

• Soy Sauce-Marinated Crab (간장게장) – If you like seafood, don’t skip this one. Fresh crab is marinated in a savory soy sauce-based sauce until the meat and roe soak up all that flavor. It’s usually served with rice, and mixing the roe and sauce into a bowl of rice is honestly the best part.
• Grilled Gizzard Shad (전어구이) – Jeoneo is one of the fish most associated with autumn in Korea. It’s grilled whole and has a rich, slightly nutty flavor. You’ll see it especially often at seafood restaurants in coastal areas during the fall season.
• Roasted Chestnuts (군밤) – You’ll start seeing chestnuts everywhere once the weather gets cooler. They’re roasted until warm and slightly smoky, with a naturally sweet flavor. They’re an easy snack to pick up while walking around a traditional market or exploring an autumn festival.
• Roasted Sweet Potatoes (군고구마) – A simple Korean autumn classic. The outside gets slightly charred while the inside becomes soft, sweet, and almost creamy. They’re especially satisfying on a cool evening, and you may find them at street stalls, markets, or convenience stores.
• Persimmons (감) – Autumn is persimmon season, so October is a good time to try Korean varieties while they’re fresh and sweet. You’ll also see gotgam, or dried persimmons, which have a chewier texture and much more concentrated sweetness.
