Naejangsan Autumn Foliage 2026: Korea's 108-Tree Maple Tunnel Is About to Turn Red (And How to Beat the 100,000-Person Crowd)
Everyone races to Seoraksan in October. The locals who actually plan their leaf-peeping know the second act happens in the south, and it starts about a week from now.
Quick question before you book that Seoraksan bus: what happens when you arrive on the "peak" weekend and the trail looks like a rush-hour subway platform?
That is exactly why a smaller group of Korean hikers heads to Naejangsan National Park in Jeongeup instead. It is often called the most famous fall-foliage destination in the south, and the timing works in your favor: the leaves begin to change around mid-October, which means that if you are reading this on October 8, you still have time to plan a trip that lands right on the color wave.
Why This Mountain Gets Its Own Pilgrimage
Naejangsan used to be called Yeongeunsan, after the temple at its foot. It was renamed because the mountain is said to "hide" countless treasures within its folds, and honestly, that is the best way to describe it. From the entrance you cannot see the show. You walk in, and the valley opens up like a bowl filled with red.
Most foliage guides rank spots by how photogenic they are. I rank them by how much the walk changes your mood. The Naejangsan approach does something the cable-car-and-selfie places cannot: it makes you slow down for twenty minutes before the payoff even arrives.
When to Go (The Honest Timing Guide)
Color changes begin in mid-October, peak around the first week of November in the source I relied on, and the last leaves fall by mid-November. Another travel guide places the deep red in the second half of October. The sensible reading: nature does not follow a calendar, so aim for the last week of October through the first week of November and check the national foliage forecast a few days out.
Seoraksan peaks earlier, around the second week of October. Naejangsan peaks later. If you love autumn leaves, you can chase them for nearly a month by going north first and south second.
| Window | What to expect | Best for |
|---|---|---|
| Mid-October | First color, green still mixed in | Quiet walks, fewer people |
| Late October | Deepening reds and oranges | The best balance of color and crowd |
| First week of November | Peak color, heaviest crowds | Photographers who arrive at opening |
| Mid-November | Leaves falling, carpet of red on the ground | Moody photos, cold weather gear |
Three Ways to Hike It, Depending on Your Legs
The easy loop: Wonjeokam Hermitage
Mostly flat and shaded, which makes it friendly for families and beginners. Just before the hermitage you hit a steep staircase that takes around ten minutes, so keep a little energy in reserve.
The scenic loop: Byeongnyeonam Hermitage
This route passes a pavilion with mountain views and a large ginkgo tree, and the trail is downhill after that point, which your knees will appreciate.
The lazy-genius option: cable car
The cable car runs from 9:00 AM to 5:30 PM and costs W11,000 round trip for adults and W7,000 for children. At the top, a roughly 300-meter walk leads to the Yeonjabong Peak viewpoint. Weekend lines can be long, so go early or accept the wait.
Crowds build from around 10 AM. If you arrive at the park gate before then, you get the maple tunnel almost to yourself for the first hour, and the low morning sun hits the leaves from behind. That light is worth the early alarm.
Getting There From Seoul Without a Car
Also worth knowing: the park was testing an "AI Travel Butler" service through April 2026 that offered QR-code route suggestions and real-time congestion levels. Availability this season is not something I could confirm, so check at the visitor center.
What to Eat Around the Mountain
Do not expect a gourmet strip. Expect something better for a cold day: stalls near the entrance and temple area selling crispy pajeon (savory pancakes) with makgeolli, Korea's milky rice wine. A quieter local restaurant on the Wonjeokam trail serves ramen, jeon and makgeolli, which is exactly what hiking calls for. Jeongeup is also known for its hanu (Korean beef), and a beef dinner in town is a fair reward after a long day, though I did not verify specific restaurants, so ask your guesthouse host for a local pick.
If your itinerary allows, add Jeonju, the home of bibimbap, as a second stop. It is the same province and an easy pairing for a two-day trip.
Key Takeaways
- Naejangsan's leaves start turning in mid-October and peak from late October into early November, later than Seoraksan.
- Entry is free, the cable car costs W11,000 round trip, and crowds build from about 10 AM.
- From Seoul, take the KTX to Jeongeup (about 1.5 hours), then bus #171 to the park entrance.
Final Thoughts
Korea does autumn better than almost anywhere, but the best version is rarely the one on the front of the tourism poster. Walk the maple tunnel slowly, drink the makgeolli, and let the 108 trees do their quiet work.
Your turn: if you had to pick, would you chase Seoraksan's early peak or Naejangsan's late one? Tell me in the comments, and I will plan the next route around your answer.
