Climate Card vs M-PASS 2026: Which Seoul Pass Is Cheaper

There are two transit passes aimed at visitors to Seoul, and one costs three times the other. That alone would be an easy decision. The complication is that the cheap one does not get you to Incheon Airport, and a lot of people find that out at the ticket gate on the morning of their flight.

This post lays out what each pass costs, how many rides it takes before either one pays for itself, and the exact list of what the Climate Card will not cover. All figures come from the Seoul Metropolitan Government and the Korea Tourism Organization, checked on the day this was written.

The prices, side by side

Look at the three-day row. 10,000 against 30,500. If the two passes did the same thing, nobody would ever buy the second one. They do not do the same thing, and the difference is mostly about the airport.

How many rides before it pays off

Seoul raised the subway base fare to 1,550 KRW by transportation card in June 2025, up from 1,400. Cash payers pay 1,650. That is the number the whole calculation runs on.

The city's own framing is that the pass suits "tourists who typically use public transportation two to three times per day." That matches the arithmetic. The five-day pass breaks even at two rides — which is one trip out and one trip back, every day. Almost anyone staying five days clears that.

The one-day pass is the weakest of the four. Four rides in a single day is a busy day, and if you spend the afternoon walking around one neighbourhood you will not get there.

Two things make the passes better than this table suggests. Buses count as rides, and Seoul has a lot of buses. And the public bike share, Ttareungi, is included, which is genuinely useful along the Han River.

The airport problem

This is the part worth reading twice. The Climate Card covers the AREX airport line only between Gimpo International Airport and Seoul Station. Incheon, where almost every international flight lands, is outside the zone.

M-PASS, by contrast, includes AREX — the city government's description covers "subway and city buses in Seoul and AREX (excluding express trains)". That is a large part of what the extra 20,000 KRW is buying.

The full exclusion list for the Climate Card:

There is a second rule that catches people mid-trip. If you board inside the service area but get off outside it, station staff charge you a separate fare on the way out. The city's own example is boarding at Seoul Station and trying to exit at Indeogwon.

Three stretches are exceptions where you may exit outside the zone: Line 5 from Misa to Hanam Geomdansan, Line 7 from Seoknam to Kkachiul, and AREX between Incheon Airport Terminal 1 and Terminal 2. Note the wording on that last one — you may exit there, but boarding at those stations is not valid. It does not turn the card into an airport ticket.

Where the subway lines actually stop

Some lines are covered end to end and some are not. The ones that run entirely inside the zone are Lines 2, 3, 6, 8 and 9, plus the Sillim, Ui–Sinseol and Gimpo Gold lines. The rest are partial:

For a first trip that stays in central Seoul — palaces, Myeongdong, Hongdae, Gangnam, the Han River — none of these boundaries will bother you. They start to matter if you plan a day trip out to Suwon, the DMZ or Nami Island.

Buying one, step by step

Climate Card Tourist Pass. You buy the physical card, then load the pass onto it. The city lists these sales points: the Tourist Information Center at Seoul Tourism Plaza in Jongno-gu, the Myeongdong Tourist Information Center, customer safety centres in subway stations on Lines 1 to 8, and convenience stores near subway stations.

Top-up machines are at stations on Lines 1 to 8, Line 9, the Sillim Line and the Ui–Sinseol Line. One note on payment: at the Seoul Metro information centres the card is cash only, while convenience stores take cash or card. Corporate cards are not accepted anywhere in the system.

M-PASS. Issued and returned at Tmoney Town near Seoul Station, Exit 10. It is cash only, in Korean won. It is valid for 30 days from the issue date, allows up to 20 rides a day, and there is a quirk worth knowing: buy it after 17:00 and you automatically get 3,000 KRW off.

The timing trap

The single most expensive mistake with the Climate Card is loading it too early. The city puts it plainly:

"unlike the 30-day pass which allows the user to select a start date within 5 days of charging, these passes activate immediately on the day of charging, requiring careful planning by the user."

So if you land at 9pm, take the airport bus to your hotel, and load a 3-day pass that night out of enthusiasm, you have just spent one of your three days on three hours of sleep. Load it on the morning you actually start moving.

One more thing about physical Climate Cards. They must be registered online through the Tmoney Card & Pay website. An unregistered card cannot be refunded and cannot be used with the Ttareungi bikes, which removes one of the better reasons to have it. Registration is one card per person.

So which one

The combination that works for most visitors is not either pass on its own. It is a Climate Card for the days you are moving around Seoul, and the airport handled separately — the limousine bus or the AREX express, bought as a single ticket. That costs a little more than an all-in-one pass would in theory, and considerably less than M-PASS does in practice.

There is also a small bonus most people never use. Climate Card holders, including tourist pass holders, get 50% off admission at places like the Seoul Science Center and Seoul Grand Park. Not a reason to buy it, but worth knowing once you have.

A word on the alternatives, since the transport card aisle in a Korean convenience store is more crowded than it needs to be. A plain T-money card works on every bus, subway and taxi in the country, and in most convenience stores as well — it is the safe default and the one to buy if you are unsure. WOWPASS is a different animal: it doubles as a prepaid debit card you top up with foreign currency at kiosks, so it suits people who would otherwise be hunting for an ATM. It needs your passport to buy. None of these are mutually exclusive; plenty of visitors carry a Climate Card for Seoul and a T-money for everything outside it.

One last practical point. Whichever card you end up with, tap it on both the way in and the way out. Seoul charges by distance beyond the base fare, and forgetting to tap out leaves a penalty on the card that has to be cleared at a station machine before the card works properly again.
