South Korea In October: Autumn Travel Guide 2026

October may be the month when South Korea looks nothing like the Korea you see in summer photos.

The first sign that summer is over in South Korea isn’t the calendar. It’s the trees. One week, the streets look familiar; the next, parks and palace grounds turn yellow, orange and red. That’s what makes South Korea in October so interesting. October is also a popular month for autumn getaways, so checking cheap flights to Seoul early can help. But where should you go for the best autumn views? Let’s find out.

Weather In South Korea In October

Weather in South Korea in October is cool and pleasant, which makes it a great time to walk around and see the sights. In Seoul, the afternoons reach about 20°C and the nights drop to around 11°C, while Busan stays a little warmer. South Korea temperatures can fall fast once the sun goes down, especially up in the mountains, so a jacket and some light layers really help. Good walking shoes are also a smart idea. South Korea weather can be different from one region to another, so it’s worth checking the local forecast before you head out for the day.

The best places to visit in South Korea in autumn include a mix of lively cities, historic towns, islands, and mountain areas. October is particularly appealing because visitors can combine outdoor sightseeing with autumn foliage without dealing with the heat of summer.

1. Seoul – Autumn Parks And Palaces

Seoul is an easy starting point for South Korea in October, especially for first-time visitors. Gyeongbokgung Palace, Seoul Forest, Olympic Park and Namsan Seoul Tower are popular places for seasonal colour. The autumn colours in Seoul are especially noticeable around palace grounds and large parks. Bukhansan is also worth considering later in the month, with 2026 forecasts expecting foliage to begin around October 23 and reach its peak around November 4.

With Seoul as a convenient base, staying somewhere close to a metro station can make early starts and day trips much less tiring. Comparing best hotels in Seoul by location, transport access, and nearby facilities can make a noticeable difference to the trip

2. Nami Island – Colourful Autumn Foliage\

Nami Island is a popular day-trip option from Seoul and is known for its tree-lined paths. South Korea’s autumn foliage becomes more noticeable as October progresses, although the exact timing depends on weather. The island works well for visitors looking for a slower day away from the city. Arriving early is useful during peak weekends, when popular walking routes can become quite busy.

3. Busan – Coastal Views And Autumn Walks

Busan offers a different side of South Korea in October, combining coastal views with city neighbourhoods and outdoor walks. Haeundae, Taejongdae and Gamcheon Culture Village can be added to a flexible itinerary. The coastal climate is also milder than many inland areas. After sightseeing, an evening around the waterfront makes for an easy change of pace, especially when the weather remains comfortable.

4. Jeju Island – Scenic Trails And Countryside

Jeju Island is a good choice for open landscapes, coastal roads and short nature walks. Hallasan is the island’s main mountain, with the 2026 foliage forecast expecting its first autumn colour around October 31 and peak foliage around November 13. South Korea in autumn feels different here, with volcanic landscapes, countryside and coastline sharing the same itinerary. October also avoids the intense summer heat, making outdoor exploration easier.

5. Gyeongju – History, Temples And Autumn Colours

Gyeongju combines historic attractions with seasonal scenery, making it an interesting stop during autumn in South Korea. Bulguksa Temple is among the notable foliage locations highlighted in Korea’s 2026 forecast. The historic surroundings look particularly appealing once the trees begin changing colour. Rather than rushing through every attraction, visitors can spend more time around Bulguksa and the surrounding heritage areas.

6. Seoraksan National Park – Mountain Foliage And Hiking

Seoraksan National Park is one of the key destinations for autumn scenery. The 2026 forecast expects its first foliage around October 3 and peak colour around October 25. South Korea autumn activities here range from shorter walks to longer mountain hikes. Proper walking shoes are essential, and trail conditions should be checked before setting out. Late October can be particularly attractive for those hoping to catch the mountain at peak colour.

Walk through Gyeongbokgung Palace and nearby streets while the weather remains comfortable and the trees begin changing colour.
Take a day trip to Nami Island for tree-lined paths, seasonal views and a break from Seoul’s busy streets.
Visit Seoraksan National Park around its expected late-October peak for hiking and mountain scenery.
Explore Gyeongju’s historic sites and Bulguksa Temple while autumn colour begins appearing around the heritage areas.
Spend an evening along Busan’s waterfront after exploring the city’s markets, neighbourhoods and coastal attractions.
Try Korean street food and seasonal dishes at local markets between sightseeing stops.
Take short countryside walks in Jeju when the weather is comfortable and the summer crowds have eased.

Before finalising the itinerary, it’s worth checking the latest South Korea visa requirements, as entry rules and documents can vary depending on the traveller’s nationality. Getting the paperwork sorted early leaves more time to focus on flights, stays and the autumn itinerary

What To Eat In South Korea In October

Food is a big part of exploring South Korea in October, especially when cooler evenings make warm dishes more appealing. Try Korean barbecue, tteokbokki, hotteok, japchae, and hearty soups during city walks. Busan is a good place to look for fresh seafood, while traditional markets offer quick snacks between attractions. Visitors staying longer can also explore regional specialities rather than eating the same dishes throughout the trip. A food market stop can easily become an unplanned highlight.

Carry layers instead of one heavy jacket, as afternoons can feel mild while mornings and evenings become noticeably cooler.
Book accommodation early if visiting during peak foliage weekends, especially around Seoul, Nami Island, and Seoraksan.
Check foliage forecasts close to departure because actual dates can shift depending on temperature and rainfall.
Wear comfortable shoes because palace grounds, markets, parks and mountain trails involve plenty of walking.
Keep some cash available for smaller food stalls, traditional markets and local purchases.
Consider options for securing travel insurance before a trip, particularly when the itinerary includes hiking or several destinations.
If planning a longer trip, compare the South Korea tour package options alongside an independent itinerary to see which arrangement suits the travel plans.

Closing Note

October brings together many of the things that make the country interesting to explore: comfortable weather, colourful parks, historic neighbourhoods, mountain trails and plenty of food stops. The 2026 forecast suggests Seoraksan should peak around October 25, while Hallasan is expected to peak later in November. That makes timing important for foliage fans. For anyone planning a first visit, South Korea in October offers enough variety to build a relaxed itinerary without trying to cover the whole country at once.
