Only the summit sections of the Seongpanak and Gwaneumsa trails need a booking. The other five trails need none. Foreigners book on the English page of the park's reservation site. From October to March the park opens at 05:00, and the last start at the trailhead is 11:30. We read the park office and reservation site on 11 October 2026.

Note: Gwaneumsa reopened: the Samgakbong to summit section reopened on 24 September 2026 after construction. Bookings restarted on 21 September at 09:00 (park office notice, 21 Sep 2026)

How a foreigner books

Booking: Booking site: visithalla.jeju.go.kr, with a language menu in Korean, English, Japanese and Chinese. The home page picks the trail, the date and 1 to 4 people (read 11 Oct 2026)

Booking: Sign-in: Kakao login, or a "non-member verification" with your name and an email address, where the site sends you a code. The page says foreigners who cannot verify a real name should use the email code on the foreign-language page (sign-in page, 11 Oct 2026)

Note: We opened the home page and the sign-in page, and we did not book. The home page showed "Reservation unavailable" for 12 October on both trails. We do not know whether that meant full or closed

Keep the same sign-in method for the whole booking. The park office says you can only cancel with the login you used to book.

Note: A park office notice of 30 September 2026 is titled as a change to winter entry and descent times. Its text only lists the 05:00 start and the weather closure rules, so we cannot say what changed. Confirm the times on the park office site before you go

What is checked here and what is not

Checked on 11 October 2026: the Hallasan National Park Office pages for trails, fees and safety, its notices of 24 April 2025, 10 June 2026, 21 September 2026 and 30 September 2026, and the trail reservation system's English home page, sign-in page, reservation guide and fee page.

Not checked: how the booking screens work after sign-in, whether foreigners get a full allotment of slots, what the no-show penalty is, the bus routes to the trailheads, the 30 September 2026 winter-time change in detail, the hwpx guideline attached to the 10 June 2026 notice, and current conditions on the trail. We did not book a slot or hike.
