Free ranger-guided walks in four national parks — October 2026 only

On 1 September 2026 the Korea National Park Service posted a notice on its reservation site announcing a free month for its eco-education centre programmes. The programmes concerned are what the service calls its signature interpretation programmes, each named after the interpreter who leads it, and eight of them run through October at four centres: Jirisan, Hallyeohaesang, Byeonsanbando and Bukhansan.

Why you should not take "free" at face value

Check this before anything else. The booking screen will not show zero. The document attached to the notice states that you pay the programme fee when you book, and once your attendance has been confirmed the fee is waived in full within seven days. It is payment up front and reimbursement afterwards.

• You need a means of payment at the booking stage. The reservation is only confirmed once payment goes through.
• The waiver happens after the event. Book and then not turn up and there is no confirmed attendance to trigger it.
• Allow up to seven days for the money to come back. Nothing is refunded over the counter on the day.

What a "signature interpretation programme" is

These are guided programmes built around an individual interpreter's name and subject, so the title tells you who is leading it and what it is about — one is photography in Jirisan, another is its woodland birds. That is why the eight on offer are so unalike: photography, birdwatching, a walking talk, an island climb, a shoreline stroll and forest meditation are all in the same list. All of them are led in Korean.

All eight programmes and their dates

The full list as published in the notice's attachment. Some programmes run more than once, so check the time as well as the date.

Added up by centre, that is four sessions and 40 places at Jirisan, ten sessions and 150 places at Hallyeohaesang, one session and 20 places at Byeonsanbando, and one session and 8 places at Bukhansan. The earliest start is the 6am island climb at Hallyeohaesang; the narrowest door is the 8-place forest meditation at Bukhansan.

Which centre to choose

Hallyeohaesang has by far the most room: three programmes, ten sessions and 150 places, more than half the whole offer, and with several Sunday sessions it is the easiest to fit into a weekend. It is a coastal park of islands in the south, reached via Tongyeong. Bukhansan is the hardest to get into — it is the park inside Seoul, so it is the most accessible of the four, but it has one session and eight places, which is the sharpest competition in the list.

Jirisan offers the widest choice of subject: photography (16 and 31 October), birdwatching (2 October) and a walking talk (24 October) inside one month. Byeonsanbando has only one session but the largest single group, at 20 places.

How booking works

Bookings are taken only through the Korea National Park reservation site at res.knps.or.kr. The site has an English toggle, but an account is needed and the account is opened with Korean real-name verification. The steps are:

1. Sign in at the reservation site.
2. From Reservations at the top of the page, choose the eco-education centres.
3. Pick the programme and the session you want and reserve it.
4. Pay from My reservations in the My page section — the booking is only confirmed once payment clears.

Getting there, and whether you can actually book

Be clear-eyed about the barrier first. Opening an account on res.knps.or.kr means passing a Korean real-name check, offered as either a Korean mobile number or an I-PIN, and the social logins route through the same requirement. A traveller with no Korean phone number or resident registration cannot complete that online, and the 1670-9201 call centre is Korean-language only. If you live in Korea, none of this is an obstacle and the English interface covers the rest of the site. Bukhansan is the one of the four you can reach on a Seoul transport card: take Line 3 to Gupabal or the Ui LRT towards the northern trailheads and the park office publishes the bus connections. Jirisan's centre is near Gurye in South Jeolla, reached by KTX to Gurye-gu and a local bus; Hallyeohaesang's is on the south coast near Tongyeong, an express bus from Seoul of about four hours; Byeonsanbando's is on the west coast near Buan. All eight programmes are led in Korean by a named interpreter, and no English-language session, interpreter or printed material has been announced — so if your Korean is limited, treat the walk itself as the point and ask questions afterwards.
