How to Book Taiwan HSR Tickets: The Foreigner Discounts Nobody Tells You About
If you’re on a foreign passport, don’t pay full HSR fare. Traveling as a pair to central or southern Taiwan, the buy-one-get-one promo on Klook or KKday is the runaway winner (roughly half price each). Solo, take the foreigner-only 15% discount — no booking race required — or gamble on the 35% early-bird quota if you can book the moment your date opens. The unlimited passes only pay off if you’re doing three or more long rides in a few days.
Taiwan’s high-speed rail is the best way up and down the west coast — Taipei to Kaohsiung in about 90 minutes, trains every few minutes at peak, and the whole system runs with a punctuality that makes airlines look embarrassing. The interesting part is what you pay, because the spread between the worst and best price on the same seat is enormous.
How fares work
Standard reserved fares are fixed: Taipei-Taichung NT$700 (~US$22), Taipei-Tainan NT$1,350, Taipei-Zuoying (Kaohsiung) NT$1,490 (~US$46). Booking opens 28 days ahead. There are also non-reserved cars — a few carriages of first-come seating, slightly cheaper, no booking needed — which are a fine fallback on weekdays and a standing-room bet on weekends and holidays.
Now the discounts, ranked by how much they actually save.
1. The buy-one-get-one (pairs, heading south)
The “Go 2 Taiwan” promo, run with the tourism administration: buy one ticket, the second is free, for foreign visitors heading to Taichung, Changhua, Yunlin, Chiayi, Tainan or Kaohsiung. Sold through Klook and KKday only, one use per passport, identical itinerary for both passengers, while stock lasts (it’s been running since March 2025 and was still live at last check — the page will tell you).
For two people Taipei→Kaohsiung round trip, this works out around NT$1,266 per person instead of NT$2,980. That’s not a discount, that’s a different price category. If you’re a pair and this promo is alive when you book, stop reading and use it.
2. Early bird (solo travelers with fast fingers)
10%, 20% or 35% off reserved seats, released when booking opens 28 days out. The 35% tier is a small quota that evaporates almost immediately on popular trains — if you book the morning your date opens, you have a real shot; if you book “a few days ahead,” you’ll find 10% or nothing. Early bird is open to everyone (locals included), booked on the official site or app, and isn’t sold at station counters.
3. The foreigner 15% (no race, no stress)
Foreign-passport visitors can buy one-way reserved standard tickets at a flat 15% off through the THSRC pass site, Klook or KKday, with child tickets at 50% off. No quota panic, no 28-day planning. This is the sane default for solo travelers who don’t want to schedule their life around a booking window.
4. The passes (do the math first)
As of 2026 only two passes exist — the 5-day passes you’ll see in older guides were discontinued:
- 3-Day Pass (consecutive days): NT$2,200 list, often ~NT$2,090-2,199 on Klook/KKday
- Flexible 2-Day Pass (any 2 days within 7): NT$2,500 list, ~NT$2,375 reseller
Foreign short-term visitors only; redeem at any HSR counter with your passport; travel can’t start the same day you buy. Standard car only.
The math: a Taipei-Kaohsiung round trip is NT$2,980 standard, so the 3-day pass saves money on that alone — but the early-bird round trip (~NT$1,938) and the BOGO pair (~NT$1,266 each) both beat it. A pass wins when you’re doing three or more long legs in a short window: Taipei → Taichung → Kaohsiung → Taipei inside three days, that kind of sprint. One round trip? Use the discounts above instead.
(There’s also a “Taiwan PASS” HSR edition at NT$2,800 bundling 3 days of HSR with a city metro pass and a scenic shuttle — same logic, just more moving parts.)
Worked example: Taipei → Kaohsiung round trip, one person
| How you book | Round trip cost | Catch |
|---|---|---|
| Buy-one-get-one (per person, as a pair) | ~NT$1,266 | Pairs only, south-bound, stock-limited |
| Early bird 35% | ~NT$1,938 | Book the second your date opens |
| Foreigner 15% | ~NT$2,533 | None — the easy button |
| 3-Day Pass | NT$2,090-2,200 | Only wins if you ride more than this |
| Standard fare | NT$2,980 | Paying retail like a chump |
Booking, step by step
- Pairs going south: Klook or KKday → the buy-one-get-one product → book with passports → redeem per instructions.
- Everyone else: the official THSRC app is honestly the smoothest — pick train, pay, get a QR ticket. The foreigner 15% tickets live on the pass site and the reseller apps.
- At the station: counters and machines sell full-fare and non-reserved tickets any time. Weekday non-reserved is the zero-planning option.
The card-declined problem: foreign credit cards fail on the THSRC website often enough that it’s a recurring traveler complaint. Fixes, in order: use the THSRC app instead (better card handling), book the same ticket through Klook or KKday (their payment systems are built for international cards), or buy at a station machine or counter, which take cards happily. Don’t burn an evening retrying the website.
Worth knowing: regular EasyCards don’t work for HSR reserved tickets — it’s a separate system. And if you’re landing at Taoyuan airport and heading straight south, the HSR station is one short MRT hop from the terminals; details in the airport guide.
Kids, luggage, seats
Under-6s ride free without a seat; under-12s are half fare (passport at the counter). Luggage is easy — racks at car ends plus generous overhead, no size-policing for normal suitcases. Seats are 2+3 in standard; if you want the quiet end of a car, the ends fill last.
FAQ
Do I need to book Taiwan HSR in advance?
Weekdays, not really — walk up and buy, or ride non-reserved. Friday evenings, Sundays, and any holiday weekend: yes, book ahead, trains genuinely sell out. And if you want the early-bird discounts, “in advance” means the full 28 days.
Why is my credit card declined on the THSRC website?
It’s a known issue with foreign cards, not your bank being weird. Use the THSRC app, book through Klook/KKday, or pay at a station machine — all three take international cards reliably.
Are the HSR tickets on Klook and KKday legit?
Yes — both are officially designated sales channels, and they’re where the foreigner-only deals (the 15% off and the buy-one-get-one) actually live. You redeem with your passport; the ticket is a normal THSR ticket.
Is the 3-day HSR pass worth it?
Only if you’re riding a lot in a short burst — three-plus long legs in three days. For a single round trip, the early-bird or buy-one-get-one prices beat the pass. The 5-day passes you may have read about were discontinued; don’t plan around them.
Can I use an EasyCard on the HSR?
Not for regular reserved tickets. The HSR has its own ticketing; EasyCard covers the metro, buses and regular TRA trains instead.
