If you'll ride more than roughly four or five times a day inside Seoul, buy a Climate Card short-term pass. If you're riding two or three times a day, or mixing subway trips with intercity rail and taxis, a plain rechargeable T-money card is simpler and you won't leave money on the table. Everything else — which app, where to tap, what to do about the last train — is detail you can sort out in your first thirty minutes at the airport or at any station machine.
This guide needs a 2026 date stamp because Seoul's transit pricing has changed twice in the past year or so, and the English-language travel web is still full of screenshots from 2023 and 2024. Fares went up on June 28, 2025. The foreign-card purchase rule changed in mid-March 2026, and on October 1, 2026 Seoul ended the 30-day Climate Card while widening what the tourist passes cover. Either one of those is the kind of update that quietly makes an older guide wrong.
What the subway actually costs in 2026
Seoul's system is distance-based, not flat-rate. You tap in, you tap out, and the gate calculates how far you went. Per Seoul's official fare information, the adult card fare works like this:
| Rider type | Base fare (first 10km, card) | Added per distance step |
|---|---|---|
| Adult | ₩1,550 | +₩100 per 5km up to 50km, then +₩100 per 8km |
| Teen (13–18) | ₩900 | +₩80 |
| Child | ₩550 | +₩50 |
In practice, almost every trip a tourist makes inside central Seoul — Hongdae to Gangnam, Myeongdong to Seongsu — lands in the ₩1,550 to ₩1,750 band. Going out to the far suburbs costs more. The base fare took effect June 28, 2025 and is still the 2026 baseline, so treat any number below ₩1,550 as stale.
One mechanical thing that trips people up: you must tap out. The fare isn't finalized until you touch the card at the exit gate. Skipping it can cause penalty charges on a normal card.
T-money vs. Climate Card: how to actually choose
A T-money card is a rechargeable stored-value card. You buy the plastic at a convenience store or station machine, load won onto it, and tap. It works on subways, buses, many taxis, and convenience stores. It's not a pass — you pay per ride.
The Climate Card (기후동행카드, "Gi-hu Dong-haeng Card") is Seoul's unlimited-ride transit pass. It launched in 2024 as a monthly pass for residents, with short-term tiers added later for visitors. In 2026 Seoul ended the 30-day version and folded its resident benefits into the national K-Pass system, but the short-term passes for visitors continue. As of 2026 the pricing is:
| Pass | Price | Break-even vs. ₩1,550 rides |
|---|---|---|
| 1-day | ₩5,000 | ~4 rides |
| 2-day | ₩8,000 | ~3 rides/day |
| 3-day | ₩10,000 | ~2.2 rides/day |
| 5-day | ₩15,000 | ~2 rides/day |
| 7-day | ₩20,000 | ~1.9 rides/day |
Look at the longer tiers — the 5- and 7-day passes break even at under two rides per day, which almost any sightseeing itinerary clears. The 1-day pass is the weakest deal at four rides. The 1-day pass also doesn't include Ttareungi bike share or the Hangang bus, per Seoul's official notice. From October 1, 2026, a short-term pass covers Seoul's subway lines, Seoul's city and village buses (including late-night and circular buses), and AREX rides that end at Incheon Airport Terminal 1 or 2, which makes it useful on your departure day too.
Short-term passes run on a 24-hour clock tied to service hours: valid from the first train (04:00) on your start date through the last train on the end date, which in practice runs to about 04:00 the following morning.
The March 2026 change that made this much easier
Until early 2026, buying a Climate Card as a foreigner was annoying: you generally needed Korean cash or a domestic card, which meant finding an ATM before you could find a train. That changed in mid-March 2026, when Seoul Transportation Corporation enabled purchases and recharges of Climate Card short-term passes using overseas-issued credit and debit cards at the newer ticket machines across Lines 1–8.
Several months on, the practical effect is that the "cash only" warning you'll still find in 2024-era guides no longer holds for short-term passes. One caveat worth keeping: the rule as published covers short-term passes at the new-model machines on Lines 1–8. Older machines and lines run by other operators aren't covered by that same notice, so if a machine refuses your card, walk to a different one rather than assuming the whole system is broken.
If you buy a physical Climate Card, register it on the T-money Card & Pay website — one card per person. Unregistered cards can't be refunded, which is the single most common way tourists lose money on this product.
The tag-out detail most English guides get wrong
Short-term tourist passes aren't hit with the suspension penalty that applied to the old 30-day card for repeated missed tag-outs. Tap out every time anyway: it keeps your transfers and trip record clean, and it's how the gates are designed to work.
Which app to use for routes and last trains
You have two solid options, and they serve different purposes.
- Cyber Station (seoulmetro.co.kr) — the operator's own trip planner, with an English interface, route search, fare calculation, and a per-station last-train lookup. It's the authoritative source because Seoul Metro runs it. Seoul's open-data portal confirms the underlying last-train dataset for Lines 1–8 was still being updated as of August 23, 2026.
- Subway Korea (third-party app) — long-running, popular for clean vector maps and real-time schedules, and it covers Seoul, Daejeon, Daegu, Busan, and Gwangju in one app. Handy if your trip includes other cities.
- T-money GO — the app you'll use to manage a registered Climate Card number.
On "what time is the last subway in Seoul?" — there isn't one answer. Last trains vary by line, by station, and by direction, and the gap between the last train at a central interchange and the last train at an end-of-line station can be substantial. Look up your actual station in Cyber Station or Subway Korea before a late night out. Treating "around midnight" as a universal rule is how people end up paying for a long taxi ride.
A 10-minute arrival checklist
- Decide pass vs. pay-per-ride using the break-even table above. Two-plus rides a day for five days? Take the pass.
- Buy at a new-model machine on Lines 1–8 if you want to use a foreign card (possible since mid-March 2026).
- Register a physical Climate Card on the T-money Card & Pay site immediately — no registration, no refund.
- Install Subway Korea or bookmark Cyber Station's English page.
- Tap in and tap out, every single trip.
- Bookmark your home station's last-train time on day one.
FAQ
Is the Climate Card worth it for a 3-day Seoul trip?
Usually yes. The 3-day pass is ₩10,000, and at the ₩1,550 base fare it pays for itself at roughly 2.2 rides per day. A typical sightseeing day in Seoul involves three to six subway trips, so most visitors come out ahead. If you're mostly walking one neighborhood or taking taxis, stick with T-money.
Can I use my Visa or Mastercard to buy a subway pass in Seoul?
For Climate Card short-term passes, yes — since mid-March 2026, overseas-issued credit and debit cards work at the newer ticket machines on Lines 1–8, for both purchase and recharge. If one machine rejects the card, try another machine; the rule applies to the upgraded units, not every machine in the system.
What happens if I forget to tap out?
Short-term tourist passes aren't subject to a suspension penalty for missed tag-outs. On a regular T-money card, a missed tap-out means the system can't calculate your distance correctly, so just make it a habit.
