Yes — the two summit trails, Seongpanak and Gwaneumsa, need a free reservation at visithalla.jeju.go.kr, while the four shorter trails need none.
That means a summit day on Hallasan is a booking decision, not just a fitness decision.
This post covers which trail to book, how long the hike takes, when to reserve for foliage season, and what the whole day costs.
Hallasan Hiking Guide: Do You Need a Reservation to Hike Hallasan?
| Seongpanak — summit, 1,947m Baengnokdam | Yes |
|---|---|
| Gwaneumsa — summit, 1,947m Baengnokdam | Yes |
| Eorimok, Yeongsil, Donnaeko, Eoseungsaengak — shorter trails | No |
You need a reservation only for the two summit trails — Seongpanak and Gwaneumsa — and the booking is free at visithalla.jeju.go.kr.
The other four trails (Eorimok, Yeongsil, Donnaeko, Eoseungsaengak) take walk-up hikers with no reservation at all.
Only Seongpanak and Gwaneumsa reach the 1,947m summit and the Baengnokdam crater lake, so if standing at the top is the goal, the reservation is not optional.
The reservation site caps Seongpanak at roughly 1,000 hikers a day and Gwaneumsa at roughly 500, so about 1,500 people can start for the summit on any given day.
Those cap numbers are approximate figures repeated across travel sources, not values from an official 2026 notice, so treat them as a scale rather than an exact count.
Park entry itself is free in every case — the reservation is the only administrative step.
Before anything else, check whether the reservation requirement is actually active on visithalla.jeju.go.kr — it has been suspended and reinstated before, so the live rule on the official site beats any guide, including this one.
If the summit is booked out and the reservation system is active, the four shorter trails are the fallback, not a lesser version of the trip.
Seongpanak vs Gwaneumsa: Which Summit Trail?
Seongpanak is the easier trail to book and the easier walk up — roughly 1,000 spots a day against Gwaneumsa’s roughly 500, on a gentler slope.
Gwaneumsa is steeper but considered the more scenic of the two, and its smaller cap means it fills faster.
Seongpanak takes 4-5 hours up and 3-4 hours down, an 8-10 hour round trip.
| Seongpanak | Gwaneumsa | |
|---|---|---|
| Daily cap | ~1,000 hikers | ~500 hikers |
| Slope | Gentler | Steeper |
| Round trip | 8-10 hours (4-5h up, 3-4h down) | Comparable 8-10 hours |
| Character | Easier to book | More scenic, books out faster |
- Book at visithalla.jeju.go.kr — reservations for both summit trails are free.
- If Seongpanak is full on your date, try Gwaneumsa — but expect it to book out sooner, because its daily cap is about half of Seongpanak’s.
- Pick Seongpanak if booking ease and a gentler grade matter most; pick Gwaneumsa if scenery matters more and your dates are flexible.
Whether Gwaneumsa closes in winter has not been confirmed for the 2026 season — it has historically closed in the cold months, so check its status on the official site before building a winter plan around it.
Whether Eorimok and Yeongsil still reach the Baengnokdam viewpoints or were shortened after trail damage is also not confirmed — verify current trail endpoints on the park site.
No-Reservation Trails With Crater Views
Four trails need no reservation: Eorimok, Yeongsil, Donnaeko and Eoseungsaengak.
They climb to high viewpoints that include views over the crater lake — but they do not reach the summit itself.
If your dates are booked out, these trails are the plan, and they still put you above the trees with crater views.
The tradeoff is straightforward: a no-reservation trail gives you a shorter day and a crater-lake viewpoint, while a reserved summit trail gives you the 1,947m top after 8-10 hours.
Park entry is free on all of them.
If the summit is the whole point of your Jeju trip, book early rather than settling for a viewpoint trail; if you just want a half-day of mountain scenery, the four shorter trails cover it without any booking step.
How Long It Takes and Why You Start Early
A summit hike takes 8-10 hours round trip — 4-5 hours up Seongpanak and 3-4 hours back down.
Trailhead cutoff times apply for the return descent, commonly cited around 13:00-14:00 depending on the trail, though the exact posted times have not been confirmed — check visithalla.jeju.go.kr before fixing your start time.
With that math, a late morning start risks reaching the top with too little daylight left for the descent window.
The cutoff turns this into a start-time decision: working backwards from an early-afternoon cutoff and a 4-5 hour climb, you want to be on the trail by early morning.
Starting early also buys slack for the sections where the pace drops on the climb.
Set an alarm, not a target pace — if the trailhead opens at 07:00 and the cutoff is around 13:00-14:00, a 07:00 start leaves the margin a 10:00 start does not.
When to Book for October Foliage
Autumn foliage on Hallasan starts in mid-October, which makes late September the window to reserve summit dates.
Foliage season is the peak demand period for summit permits, so mid-October dates are the ones that sell out first.
Booking roughly three weeks ahead is the practical rule for those dates.
- Late September: the reservation window for mid-October foliage-season dates — book at visithalla.jeju.go.kr before the booking spike.
- Mid-October: foliage starts on Hallasan — the busiest weeks for summit permits.
If your trip falls outside mid-October, the booking pressure drops and same-week reservations become realistic; if it falls inside, reserve the moment your dates are fixed.
What Hallasan Costs
Hallasan National Park entry is free, the summit trail reservation is free, and nothing is paid at the trailhead.
The only cost of the hike itself is getting to the starting point.
For a visitor, that makes Hallasan one of the cheapest full-day plans on Jeju — the budget line is transport and food, not admission.
If I were booking for foliage season, I’d reserve Seongpanak about three weeks ahead, because its larger daily cap gives the better odds once mid-October demand hits.
The first thing I check is the live reservation rule on visithalla.jeju.go.kr, since the requirement has been suspended before.
Bus routes and frequencies to the Seongpanak and Gwaneumsa trailheads were not covered in the sources used here, so plan that leg from a current transit map or the park site rather than this post.
Winter and night-hiking restriction schedules were also not confirmed from a primary page — if you are travelling outside the main season, read the posted notices on visithalla.jeju.go.kr.

- Full day, early start. 4-5 hours up, 3-4 down — start in the morning to stay inside the descent cutoff.
- Book late September for mid-October foliage — the peak demand window for summit permits.
- Costs: park entry ₩0, reservation ₩0. Transport to the trailhead is the only spend.
