Korea is small and its trains are fast. Seoul to Busan takes about two and a half hours on a KTX running at up to 330 km/h, which means a country that looks like a week-long trip on a map is actually a series of day trips from wherever you are sleeping. That fact is what makes an unlimited rail pass tempting.
The KORAIL PASS is Korail’s answer, sold only to foreign nationals. It is also surrounded by more outdated information than almost any other travel product here — consecutive versus flexible passes that no longer exist, youth tiers that are not in the price table, a six-month residency rule that does not appear in the current terms, and a wrong web address repeated on page after page. This guide works only from what Korail itself publishes, and it says plainly where the pass is a bad deal.
What the KORAIL PASS Actually Is
It is a pass that lets foreign nationals ride most Korail trains without buying individual tickets, for a set number of travel days. Korail’s own framing is that it lets foreigners visiting Korea travel across the country by train at a reasonable price.
Two words in that sentence matter more than the rest: foreigners and most. The first is the eligibility rule. The second is the reason a pass can lose you money — it does not cover everything, and it does not include a guaranteed seat.
Note the web address before anything else. The official site is korail.com. A great deal of writing about this pass points readers to a different domain, and that matters because unauthorised resellers exist and charge real markups. More on that at the end.
Who Can Buy One — and the Rule That Isn’t in the Terms
Korail states that any foreigner visiting Korea can travel with the pass, and that it is unavailable to persons with Korean nationality. Purchase requires a valid passport and a credit card.
That credit card requirement has a trap in it. A WOWPASS prepaid card — the card many visitors get on arrival precisely because it needs nothing but a passport — cannot buy this pass, because it does not work for online payments at all. If your plan was to land, get a prepaid card and then book rail travel with it, that plan does not work. Bring a card that works online.
That is the whole eligibility statement. And it is worth dwelling on what is not in it.
You will read almost everywhere that foreign residents who have been in Korea more than six months are barred, and that a separate pass exists for them instead. We looked for that rule in Korail’s published terms and it is not there. The terms as posted in November 2025 exclude one thing: Korean nationality.
We are not going to flip that into a promise, either — and here is why, stated plainly. Korail’s own pages block automated retrieval, so we could not re-read the source text directly on this update. Meanwhile several authorised and third-party sellers state the opposite of a permissive reading: that the pass is for non-residents, or that resident foreigners may not be eligible. So the honest position is that the widely-repeated six-month rule is not something we could find Korail publishing, while the broader idea that residents are excluded is actively asserted by sellers.
Do not resolve that on our word or theirs. If you hold a residence card, ask Korail before you pay — the English line is 1599-7777, open 08:00 to 22:00. Buying on an assumption here means a pass that is non-refundable the moment its start date arrives.
If you are hosting someone from abroad, this is squarely a product for them rather than for you — see our host’s guide to visitors in Korea for what else your guest can access that you cannot.
Prices, and the Only Format That Still Exists
Price verification limit — 6 October 2026: we could not retrieve Korail’s current pass terms or price table. The figures below are the earlier reference figures, not a confirmed October quote. Confirm your product, travel-day window and eligibility with Korail before paying.
| Pass | Adult | Child |
|---|---|---|
| 2 day select | ₩131,000 | ₩66,000 |
| 3 day select | ₩186,000 | ₩93,000 |
| 4 day select | ₩234,000 | ₩117,000 |
| 5 day select | ₩275,000 | ₩138,000 |
How the select format works: from your chosen starting date, you pick your travel days within a 10-day window. A 3-day pass is not three consecutive days. It is any three days out of ten.
Age brackets, which also differ from what you will read elsewhere:
- Adult — age 13 and over
- Child — age 6 to 12
- Under 6 — free, up to one child per adult aged 13 or over
There is no youth tier and no saver tier in Korail’s price table. Third-party sellers still advertise youth and group-saver passes, and older guides describe consecutive passes. Neither appears in the current official pricing. If a seller is offering you a product category Korail does not list, that is a reason to look closely at who you are buying from.
Prices are set in Korean won. A price quoted to you in another currency is a conversion, and the conversion is where a markup hides.
Which Trains It Covers — and the Tourist-Train Split
Covered, on standing and non-reserved seats:
- KTX, including KTX-Sancheon and KTX-Eum
- ITX-Cheongchun and ITX-Saemaeul
- Saemaeul, Mugunghwa and Nuriro
- Regular tourist trains
Not covered:
- SRT — a different operator entirely, running from Suseo rather than Seoul Station
- Metropolitan railway — the subway networks
- Special or temporary tourist trains
That last pair is the distinction almost every guide flattens. You will read that the pass covers scenic tourist trains, and you will read that it excludes them. Korail draws a line between its regular scheduled tourist services and special or temporary ones, and only the second group is excluded. So the answer to “can I use it on a tourist train” is: it depends which train, and you check the specific service before you plan a day around it.
The SRT exclusion is the one that catches people mid-trip. On some Seoul–Busan and Seoul–Dongdaegu searches, SRT departures appear alongside KTX ones on third-party apps. They are not the same operator and your pass will not work on them. If your train leaves from Suseo, it is not a Korail train.
The Pass Is Not a Seat
This is the most expensive misunderstanding available. Buying a pass does not put you on a train.
You reserve seats separately. Reservations open a month before the departure date, and you can select up to two seats per person per day. If you are using a transfer ticket, that drops to one per person per day. The same journey cannot be reserved twice on the same date.
If the train is sold out, you stand. Korail’s instruction is to board with a valid pass and your passport and take a standing place. On a busy Friday to Busan that is two and a half hours in a vestibule with your luggage.
First class costs extra. Pass holders are charged 50% of the first-class price for that route. The pass is an economy-class product.
Bicycles have to be folded or taken apart. Korail allows bicycles on board only when they are folded or completely disassembled, so as not to inconvenience other passengers. If you are planning a ride-and-train trip, that shapes what bike you bring — our guide to cycling across Korea covers the routes.
A screenshot is not a valid ticket. Korail states this explicitly for both the pass and seat reservations. The pass or reservation must be the live version — the actual screen when you open the site on your phone, or a print. A photo of it does not count, and this is checked.
Practical consequence: reserve as soon as your dates are fixed. Weekends, public holidays and the Seollal and Chuseok periods sell out, and a pass holder has no priority over anyone else. If you are travelling on a peak weekend, the pass saves money and costs comfort.
Where You Buy It Decides How You Refund It
Three purchase channels: the Korail website, designated sales agencies, and a KORAIL Travel Center in person — Seoul, Yongsan and Busan stations among them.
The channel is not a neutral choice, because refunds have to go back through it. Korail states that online refunds are unavailable for purchases made through travel agencies or train stations. If you bought your pass on a discount platform, you refund it there, on their terms and their timetable, not Korail’s.
That is worth weighing against the discount. A platform selling slightly below Korail’s price is offering you a real saving and a slower, less certain exit.
Two more purchase-stage rules that are easy to trip over:
- You cannot change the pass type, the passenger type, or your personal information after purchase. The fix is to refund the pass and buy a new one — which only works before the start date.
- You can change the starting date once. Once.
Refunds: One Deadline, and No Second Chances
The rule is short and unforgiving.
- Before the start date: refundable. Korail states there is no refund fee up to a day before the pass’s starting date, based on Korean time.
- On or after the start date: not refundable at all. Not at a fee — not at all.
If you have made a seat reservation, you must cancel that reservation first before the pass itself can be refunded.
Compare this to an ordinary ticket, which is refundable at a penalty right up until the train reaches your destination. The pass trades that flexibility away. Do not buy a pass “just in case” and decide later. Once the start date arrives, the money is spent whether you ride or not.
What You Quietly Give Up: Delay Compensation
Here is the clause nobody quotes.
If a KTX or general train is delayed more than 20 minutes for reasons attributable to Korail, an ordinary ticket holder can claim compensation under Korea’s Consumer Dispute Resolution Standards. The amount depends on the length of the delay and the form of compensation chosen.
Pass holders cannot. Korail’s pass conditions state that you cannot receive compensation for train delays and suspensions.
For a two-hour delay on a day you had a booking at the other end, that is a real difference. It will not change most people’s decision, but it belongs in the comparison, and it is missing from every promotional page we found.
Do the Maths Before You Buy
The pass is not automatically cheaper. Work it out with your actual itinerary.
Compare in Korean won: potential saving = the total price of the individual tickets you would actually buy minus the pass price and any additional charges. Use the same travel dates, trains and seat class. A positive result suggests a saving; it does not guarantee seat availability.
A multi-city itinerary can favour a pass, but the number of legs alone does not determine value. Price every planned journey first.
Where the pass loses:
- A return trip whose individual tickets cost less than the pass
- A trip that is mostly Seoul, where you are riding the subway and not Korail at all
- A trip built around SRT departures
- Any itinerary where you would happily take a slower, cheaper Mugunghwa anyway
A cheap sanity check: price your actual legs as individual tickets on korail.com first, add them up, and compare. Note that the airport railway into Seoul is a separate service from your first long-distance leg — see getting from Incheon Airport to Seoul for that part. Tickets can be bought from 07:00 one month before departure, and the website sells until 20 minutes before the train leaves — so there is no penalty for deciding late and buying individually.
And remember what the pass does not replace. City transit is separate: you still need a transit card for subways and buses. Our T-money guide covers the basics and Korea’s transit passes covers the city-level options that sit alongside a rail pass.
Buy From Korail, Not From a Lookalike
Korail has published its own warning about unauthorised train ticket websites in Korea, and the numbers in it are worth repeating.
For a Seoul to Busan standard-class KTX, Korail puts its official price at about 43 USD and an unauthorised seller’s price at about 76 USD. That is roughly a 77% markup for the same seat on the same train. Korail’s warning also notes that such platforms may charge excessive fees and expose you to financial loss or even invalid tickets.
We are not naming the sites. Any list we published would go stale, and the rule outlives the names: check the price against the official site before you pay. If a seller’s number is far above what korail.com quotes for the same train, you have your answer.
The .go.kr Exception Worth Knowing
Our guide to Korea’s government websites gives you a rule for immigration: if the address does not end in .go.kr, it is not the government. Korail is the exception. The official site is korail.com, because Korail is a state-owned corporation rather than a ministry, and public corporations here generally use commercial domains.
So the .go.kr test is exactly right for visas and entry declarations, and it simply does not extend to state-owned companies. Authorised resellers also legitimately exist, which means “not korail.com” on its own does not tell you anything is wrong. For a rail pass, the reliable test is the price comparison, not the domain.
Who It’s Actually For
Buy it if you are a foreign visitor doing three or more long-distance Korail legs inside a 10-day window, your dates are fixed enough to reserve seats early, and you have priced the alternative.
Skip it if you are doing one return trip, staying mainly in one city, travelling SRT routes, or unsure of your dates — the start date is a hard refund deadline.
Check first if you hold a Korean residence card, and you cannot buy it at all if you hold Korean nationality, including as a dual national travelling on a Korean passport.
FAQ
How much is the KORAIL PASS?
Adult passes are ₩131,000 for 2 days, ₩186,000 for 3, ₩234,000 for 4 and ₩275,000 for 5. Child fares are roughly half. Prices are set in Korean won and change periodically — check korail.com.
Is it consecutive days or flexible?
Flexible. All four current products are select passes: you choose your travel days within a 10-day window from your start date. The consecutive passes described in older guides are not in Korail’s current table.
Is there a youth or student price?
Not in Korail’s official price table. Adult means 13 and over. Third-party sellers still advertise youth and saver tiers; those are not currently listed by Korail.
Can foreign residents in Korea buy one?
Unresolved, and treat it that way. We could not find Korail publishing the six-month rule that circulates online, but several sellers state the pass is for non-residents. Confirm your own case with Korail on 1599-7777 before paying — the pass is non-refundable once its start date passes.
Verification note. On September 24, 2026 an AI-assisted check went back through the official sources linked in this guide and confirmed each still resolves to the same official page. I publish this guide under my own name and am responsible for what it says.

Sources & What We Could Not Verify
This guide has an unusual limitation, and it belongs at the top of this section rather than buried in it.
Korail’s own web pages block automated retrieval. On the verification date above, every Korail endpoint we tried returned an empty shell or an error rather than readable text. So unlike our other guides, we could not re-read the operator’s terms directly on this update. Everything below is flagged for how it was checked, and where sources disagree we say so rather than picking one.
- Pass format and the 10-day select window — that all current products are select rather than consecutive passes, chosen within a 10-day window / confirmed independently by two 2026 English-language rail guides and a Korean travel platform, all describing the same flexible format and window.
- Age brackets — adult from 13, child 6 to 12, one under-6 free per accompanying adult / confirmed by a travel platform product page and an independent rail guide giving identical brackets.
- Excluded services — SRT, metropolitan subway networks and temporary tourist trains / confirmed by two independent sellers and a travel platform listing the same three exclusions.
- Seat reservations and standing travel — reservations separate from the pass, capped per person per day, with standing travel when a train is sold out / confirmed by two independent sellers describing the same cap and the same fallback.
- Prices — ₩131,000 / ₩186,000 / ₩234,000 / ₩275,000 adult and ₩66,000 / ₩93,000 / ₩117,000 / ₩138,000 child, plus the roughly 43 USD and 76 USD figures in Korail’s own reseller warning and the 86 USD return comparison derived from it / partially unconfirmed. A May 2026 guide matches the 2-day and 5-day adult fares and a rail site the 2-day and 4-day, but published prices differ between sellers and one 2026 source quotes an entirely different set including youth tiers Korail does not list. Price the pass on the official site before paying.
- Residence-card eligibility — unresolved, and the most important gap here. The six-month rule repeated across the internet is not something we could find Korail publishing, but several sellers state the pass is for non-residents or that resident foreigners may not be eligible. We could not read Korail’s terms directly. Call 1599-7777 before paying.
Deliberately excluded. We have not named any reseller, because a list of sites goes stale while the underlying test does not: compare the price against the official site before paying. We have also left out add-on products and lounge or discount perks quoted in older material, since we could not confirm their current status or price from the operator.
