The arithmetic
A subway ride in Seoul costs ₩1,550 on a transit card — the base fare since 28 June 2025, covering about 10 km, with a small surcharge on longer rides. The short Climate Card passes run from ₩5,000 for one day to ₩20,000 for seven.
| Pass | Price | Rides to break even | What that means |
|---|---|---|---|
| 1 day | ₩5,000 | 3.2 | Four separate base fares cost more than the pass. |
| 7 days | ₩20,000 | 12.9 | Thirteen separate base fares cost more than the pass. |
Three rides a day for a week is 21 rides, or ₩32,550 paid per ride, against ₩20,000 on the pass. Even two rides a day would cost ₩21,700 in separate base fares. If you need to buy a physical Climate Card, include that additional cost in the comparison. Check the current price for your chosen duration before paying.
Coverage depends on the exact service and stations. Seoul’s official coverage list includes some routes beyond the city boundary and specific airport-rail exceptions. The Sinbundang Line and airport buses are excluded. Check each planned journey before counting it toward the pass’s value.
Worth it, or not
| Your trip | Verdict |
|---|---|
| 5–7 days in Seoul, 2–3 rides a day | Compare the pass and physical-card cost with your eligible separate fares. |
| A week, but day-tripping outside Seoul most days | Count only journeys on eligible routes |
| 1–2 days, mostly on foot | Paying per ride may cost less; count your planned journeys. |
| 1 day, deliberately subway-heavy | Marginal; a plain Tmoney balance is simpler |
| Planning to ride the Ttareungi bikes | Only if you can clear the I-PIN step below |
| Wanting a 30-day pass | Gone from 1 October 2026; no top-ups after 31 August |
Where the sums do not favour a pass, a plain Tmoney card (Korea's nationwide rechargeable transit card) loaded with what you need is the simpler answer — “How do I buy a physical Tmoney card?”.
Buying one as a visitor
A physical Climate Card costs ₩3,000 at subway station machines and the convenience stores near stations. Register it on Tmoney's site before first use — no Korean ID or phone number is needed for subway and bus — then load a pass onto it. Since 20 March 2025 a foreign credit or debit card buys and reloads it, and since 17 March 2026 the new machines at 273 stations on Lines 1–8 take a foreign card for exactly this — “Can I top up a Tmoney card at a subway station?”.
The bike add-on is the exception. Activating Ttareungi on the pass means registering in the TmoneyGO (티머니GO) app with a Korean I-PIN, a resident identity scheme, and Tmoney's own guide offers no way round it for a visitor. Ride the subway and buses on the pass; expect the bikes to be out of reach. Ttareungi sells its own day pass for ₩3,000 regardless.
The 30-day pass is ending
Seoul is closing the monthly Climate Card that older guides recommend. Its wind-down FAQ gives the calendar:
| Date | What happens |
|---|---|
| 31 August 2026 | Last day to load a 30-day pass |
| 1 September 2026 | Seoul residents move to the Everyone's Card (모두의 카드), a rebate scheme needing a Korean account |
| 29 September 2026 | Last day a prepaid Climate Card works |
| 30 September 2026 | Last day a postpaid one works |
| 1 October 2026 | The 30-day scheme ends |
The 1–7 day passes continue on eligible routes. There is no refund on a physical card already bought, and the seven Gyeonggi cities that had joined (Gimpo 김포, Goyang 고양, Gwacheon 과천, Seongnam 성남, Hanam 하남, Namyangju 남양주, Guri 구리) move to their own The Gyeonggi Pass (더경기패스). Check the current pass conditions rather than relying on earlier expansion proposals.
The add-ons
- Ttareungi (public bikes): ₩3,000 added to the pass via TmoneyGO (티머니GO) — the
same price as a standalone day pass of repeated three-hour rides, and cheaper than the ₩5,000 30-day membership.
- Hangang Bus (the river boat): no longer part of the Climate Card.
₩3,000 a ride by card, or ₩100,000 for a flat pass.
