As of November 6, 17 of the 21 major mountains monitored by the Korea Meteorological Administration (KMA) have officially reached peak foliage. Hallasan and Gajisan reached peak colors on November 6, while Mudeungsan, Gayasan, and Jogyesan peaked on November 3, and Songnisan and Wolchulsan on November 2. Naejangsan saw its first autumn colors only on November 3—later than the October 29 forecast by the city of Jeongeup. Although peak-foliage photo records for Naejangsan, Palgongsan, and Geumosan were logged on November 6, their official status is still marked as "first foliage." The remainder of the autumn foliage season will stretch through mid-November across the mountain valleys of Honam and Jeju, urban plains, and the southern coastal regions.
The Korea Meteorological Administration (KMA) defines "first foliage" when about 20% of the mountain turns color from the summit down, and "peak foliage" when about 80% is blanketed in autumn colors. The dates below reflect actual field observation dates from the KMA Weather Nuri Foliage Status at Famous Mountains report. Because the KMA table retains the "Peak" label even after peak colors have faded, tracking the specific observation dates offers a far more accurate picture.

Forecasts from the Korea Forest Service differed from actual observations by only a few days this autumn. The Korea Forest Service had projected peak dates of October 20 for Seoraksan, October 28 for Songnisan, November 4 for Naejangsan, and November 6 for Hallasan. In comparison, the KMA recorded actual peaks on October 16 for Seoraksan, November 2 for Songnisan, and November 6 for Hallasan. Because the Forest Service defines peak foliage when 50% or more of the canopy has turned color, dates between the two agencies inherently diverge.
November 7–8. You are right in the thick of peak foliage across the southern regions. Naejangsan is expected to hit its peak around November 7–8 according to Jeongeup City, and because the first coloring arrived late, this weekend is likely to see the heaviest crowds of the season. Mudeungsan, Wolchulsan, Jogyesan, Gayasan, and Juwangsan all hit peak earlier this week, making right now an ideal window to visit. On Jeju Island, the Eorimok trails on Hallasan—where peak was officially logged on November 6—are your best bet.
November 14–15. By this point, the focus shifts from high peaks to lowlands and the southern coast. Haenam's Duryunsan has yet to log its peak. For easy walking without steep climbs, the Damyang Metasequoia-lined Road and Gwanbangjerim Forest, along with Gyeongju Bulguksa and Seokguram, remain well worth visiting through this period. Traffic restrictions in Naejangsan will remain in effect through November 15.
From the third week of November onward. Mountain foliage will be almost entirely finished, giving way to quiet walks over fallen leaves. For a complete look at nationwide options, consult our curated guide to Best Places to Visit in November.
| Region | Destination | Status as of November 6 | Recommended Window |
|---|---|---|---|
| Gangwon | Seoraksan, Odaesan, Chiaksan | Past peak (October 14–19) | Late-season walks on fallen leaves; aim for mid-October next year |
| Seoul | Bukhansan | Past peak (October 26) | Focus on low-elevation forest trails |
| Seoul | Changdeokgung Secret Garden, Olympic Park, Inwangsan, Namsan | Late stage in urban areas | Early to mid-November |
| Gyeonggi | Dumulmeori, Hwadam Forest, and outlying areas | Late stage | Early November |
| Chungcheong | Songnisan, Gyeryongsan, Woraksan | Peak recorded (October 28–November 2) | Through this weekend |
| Jeonbuk | Naejangsan | First foliage November 3; peak imminent | Second week of November |
| Jeonbuk | Jeonju Hanok Village | Late stage for ginkgo trees | Early November |
| Gwangju / Jeonnam | Mudeungsan, Damyang | Mudeungsan peaked (November 3) | Early to mid-November |
| Gyeongbuk | Gyeongju Bulguksa and Seokguram, Juwangsan, Palgongsan | Juwangsan peaked (November 4) | Early to mid-November |
| Jeju | Hallasan | Peaked (November 6) | Through the second week of November |

With Bukhansan having logged its peak on October 26, the high ridges are winding down. However, downtown royal palaces and parks turn later than the mountains, holding their rich hues well into early November.
Three full weeks have passed since Seoraksan logged its peak on October 16. If you were hoping for vivid crimson ridges across the high peaks, your best option this year is to head south instead. That said, if you prefer peaceful valley walks with far thinner crowds, the Sogongwon and Biseondae sections offer serene autumn ambiance. Detailed routes and cable car information are outlined on our Seoraksan page.
Seoraksan. The city of Sokcho will implement special autumn foliage traffic measures from October 3 to November 8. Once the Sogongwon parking lot and access roads reach capacity, vehicle entry will be restricted in phases, directing drivers to free parking lots in Seorak-dong Districts B and C, where free shuttles run to Sogongwon. The Heullimgol trail section (Heullimgol Visitor Information Center to Yongso Falls Intersection, approx. 3.1 km one way) requires advance reservations via the Korea National Park Service reservation system through November 30, with November entry hours between 9:00 AM and 2:00 PM. On-site registration is only available if unfilled slots remain.
Naejangsan. The Naejangsan National Park Office will restrict vehicular access inside the park from October 30 to November 15, running free shuttle buses between the Naejangho Lake parking lot and Wollyeonggyo Bridge. Jeongeup City is implementing peak foliage traffic measures from October 26 to November 22, targeting October 31 to November 15 as an intensive management period when an estimated 350,000 visitors are expected. If driving, plan your route around leaving your car at the Naejangho Lake parking lot and riding the shuttle bus in. Cable car details and hiking routes are covered on the Naejangsan page.
Other National Parks. Trail closures and reservation-only sections vary by mountain and year. Check trail restriction updates and reserved sections on the Korea National Park Reservation Service before heading out. Keep in mind that even with a confirmed reservation, trails may close unexpectedly in severe weather.
Timing & What to Wear. Parking lots at popular mountains fill up early on weekend mornings. Aim to arrive before 7:00 AM, and try to catch the first cable car run of the day. According to Korea Meteorological Administration observation records, the temperature at Hallasan was 8.6°C on November 6. Early mornings on the mountain drop even lower, so dress in layers with a windbreaker and warm outer shell. Sturdy hiking boots with reliable traction are essential for navigating downhill slopes blanketed with fallen leaves.
| Style | Recommended Spots | Remaining Window |

Q. Is the autumn foliage at Seoraksan completely over? A. The official KMA peak was logged on October 16, three weeks ago. If you are after fiery red ridges across the high peaks, plan for mid-October next year.
Q. Where should I go this weekend (November 7–8)? A. Top picks include Naejangsan (approaching peak), Mudeungsan, Wolchulsan, Jogyesan, Gayasan, and Juwangsan (all recorded peak earlier this week), along with Hallasan on Jeju Island.
Q. When is the best time to visit Naejangsan? A. Its first foliage arrived late on November 3, and peak photo records were logged on November 6. Jeongeup City forecasts the peak around November 7–8. To avoid weekend gridlock, visit on a weekday during the second week of November. Keep in mind that vehicles are restricted within the park through November 15, so use the Naejangho Lake parking lot and take the free shuttle bus.
Q. Can I still see autumn foliage on Hallasan? A. Yes. First foliage was observed on October 14, and peak was recorded on November 6. You can comfortably add a half-day hike into your Jeju travel itinerary through next week.
Q. Why do government agencies report different peak dates? A. The KMA marks peak foliage when 80% of the entire mountain turns color, whereas the Korea Forest Service forecast map sets peak at 50% or more canopy coloration. Because their standards differ, reported dates for the exact same mountain can vary by several days. Use KMA observation data to track actual conditions on the ground.
