Autumn Foliage Spots

2026 Autumn Foliage Peak Season and Hotspots — When and Where to Go

For autumn foliage trips, dates are more important than locations. On the same weekend, Seoraksan might be past its peak while Naejangsan is still green. Korean autumn foliage begins in the northern high mountains each year and descends to the south and lowlands over approximately three weeks. This page compiles official 2026 predictions and observation news, along with regional hotspots and routes, tips for avoiding traffic and crowds, and photography advice, all in one place. This page is updated annually with the latest information.

2026 Autumn Foliage Peak Season at a Glance

On September 22, 2026, the Korea Forest Service announced the "2026 Korean Peninsula Autumn Foliage Peak Prediction Map," reflecting plant phenology observation data from forests and arboretums nationwide. It predicted that the peak season would begin in the northern mountainous regions of Gangwon Province in early October, reaching its peak nationwide in late October, approximately 0.8 days later than the average of the past five years.

This year's first foliage was confirmed by citizen observation on September 14 at the Jeombongsan Forest Genetic Resource Reserve.

It's important to understand the criteria to avoid confusion. The Korea Forest Service's prediction map considers the peak when over 50% of the trees have changed color, while the Korea Meteorological Administration (KMA) considers the peak when 80% of the entire mountain has changed color. Therefore, even for the same mountain, dates reported by different agencies and media outlets may vary by a few days. A Newstravel report on September 10, 2026, listed Seoraksan's peak as October 25, Bukhansan as November 4, Jirisan as November 5, Naejangsan as November 11, and Hallasan as November 13. The most reliable method is to use the official prediction (Korea Forest Service) as a baseline and then, about a week before your trip, check the actual progress on the KMA's Weather Nuri website for mountain-specific foliage status (September 21 to November 27, 21 famous mountains).

Peak Season and Representative Courses for Famous Mountains

In the mountains, colors vary even on the same day depending on altitude. Around the predicted peak date, the mid-slopes and valleys are often the reddest, and going 2-3 days earlier than the predicted date can help avoid both fallen leaves and crowds.

Detailed information on hiking trails and transportation for each mountain can be found on the linked mountain pages. National parks may restrict access to trails during bad weather or fire prevention periods, so please check the National Park Service website for control information before departing.

Autumn Foliage in Seoul and the Greater Seoul Area

Foliage in downtown Seoul and the Gyeonggi plains changes later than in the mountains, generally between late October and early to mid-November. The tree-specific predictions (Ginkgo October 30, Maple October 31) align with this period. There are many places that are sufficient without traveling far.

• Palace Foliage: Changdeokgung Huwon has limited viewing with set numbers of visitors and guided tours, so reservations fill up quickly in autumn. The area around Hyangwonjeong in Gyeongbokgung is also a good urban foliage walking spot.
• Urban Parks: Olympic Park and Haneul Park offer both foliage and eulalia grass on flat walking paths.
• Nearby List and Day Trip Itineraries: For Gyeonggi area hotspots, choose by region from the List of Seoul Urban and Nearby Autumn Foliage Hotspots, and for day trip courses, check the time-based itineraries in Seoul Nearby Autumn Foliage Day Trip Courses.
• Riverside Walks: Yangpyeong Dumulmeori is a place where you can see morning mist and autumn foliage together, so an early visit is recommended.

Southern and Jeju Foliage — Autumn Continues Until November

Even after the peak in the central region, the southern regions and Jeju offer autumn foliage until early to mid-November. If you missed the October holidays, a trip south on the first or second weekend of November is a realistic option.

• Jeonbuk Jeongeup Naejangsan: Korea Forest Service predicts peak on November 4. The foliage tunnel from Iljumun to Naejangsa and Uhwajeong are representative sights.
• Jeonnam Damyang: The Metasequoia-lined road and Gwanbangjerim are autumn courses for walking without hiking. Refer to the Damyang and Damyang Juknokwon·Gwanbangjerim Metasequoia Road pages for itineraries.
• Gyeongbuk Gyeongju: Courses combining temples and autumn foliage are summarized in the Gyeongju Bulguksa·Seokguram Autumn Guide.
• Jeonbuk Jeonju: For an urban autumn trip combining traditional hanok alleys and ginkgo trees, see Jeonju Hanok Village Autumn.
• Jeju Hallasan: Korea Forest Service predicts peak on November 6, the latest nationwide. Incorporating a half-day hike into your Jeju travel itinerary is a good approach.

Drives, Palaces, Temples — Enjoying Foliage Without Hiking

Not everyone needs to climb mountains. If you want to reduce walking distance, choose according to your purpose.

How to Avoid Traffic, Parking, and Crowds

On popular mountain weekends during foliage season, parking lots fill up early in the morning, and entrance road congestion can last for 1-2 hours.

1. Date: Aim for a weekday 2-3 days before the predicted peak, or Sunday afternoon during the peak week rather than Saturday. In 2026, traffic will be concentrated during the three-day holiday weekend starting with Gaecheonjeol (Sat, Oct 3) and Hangeul Day (Fri, Oct 9). This period corresponds to the high mountains of Gangwon (between Seoraksan's first foliage and peak).
2. Time: Arriving before 7 AM is the most reliable. For cable cars, aim for the first operating time slot due to long on-site waits.
3. Shuttle/Public Transport: Some national parks, like Naejangsan, have restricted vehicle access and operated temporary parking lots and shuttle buses during foliage season (e.g., 2023 Naejangsan free shuttle from Parking Lot 4 to Wolyeonggyo, 2.1km). Operation status and routes change annually, so check announcements from the relevant National Park Office and local government.
4. Control Information: Trails are restricted during fire prevention periods and special weather advisories. Check the National Park Service website for daily restricted sections.
5. Attire: Mountain temperatures vary greatly between morning and evening. Prepare thin layers of clothing, a windbreaker, and hiking shoes that are not slippery on leaf-covered paths.

How to Take Good Autumn Foliage Photos

• Light: In the low sun around 9 AM and after 3 PM, backlighting the leaves makes the red colors more vibrant.
• Composition: Instead of just filling the frame with foliage, include contrasting elements like stream water, rocky peaks, or temple roofs on one side.
• Overcast Days: Photographing shaded valleys or inside forest paths yields calm photos without color bleeding.

Detailed smartphone settings and location-specific compositions are summarized in the Smartphone Autumn Foliage Photo Guide.

Frequently Asked Questions

Q. When is the peak autumn foliage in 2026? A. Based on Korea Forest Service predictions, Seoraksan is October 20, Songnisan October 28, Naejangsan November 4, and Hallasan November 6. Nationwide, late October is the peak.

Q. Will there be autumn foliage if I go during the October 3 and 9 holidays? A. The high mountains of Gangwon will be starting to change color. Seoraksan's first foliage was observed on September 28, and the peak is predicted for October 20, so during the holidays, you will primarily see colors around the mountain peaks. The central plains and southern regions will still be early.

Q. Why do different agencies have different peak dates? A. This is because their criteria differ; the Korea Forest Service considers 50% colored as the peak, while the KMA considers 80%. Check actual observation news about a week before your departure.

Q. I want to see autumn foliage without hiking. A. Choose palace, temple, tree-lined road, or drive courses. In Seoul, Changdeokgung Huwon and urban parks in late October to early November are sufficient.
