The Seoul Metro is one of the cleanest, cheapest, and most tourist-friendly subway systems in the world. Signs and announcements are in English (and often Chinese and Japanese), trains are frequent, and a single ride costs only about a dollar. This guide walks you through exactly how to buy a ticket and ride, using real photos from a Seoul station, and answers the questions first-time visitors ask most.

Quick facts (2026)

Which ticket should you use?

You have a few options. For most tourists, a rechargeable transit card is the easiest, but a single-journey ticket is perfectly fine for occasional rides.

Step-by-step: buying a single-journey ticket

Step 1. Find the ticket machine

Inside every station, before the fare gates, look for machines labeled “Ticket Vending and Card Machine.” There is usually a row of them. Tap the screen to begin — you can switch the language to English at the start.

Step 2. Choose your destination station

Select “Single Journey Ticket,” then find your destination. You can search by station name or tap it on the line map. The machine automatically calculates the correct fare based on distance, so you don’t need to know the price in advance.

Step 3. Pick ticket type and quantity

Choose Adult or Child and how many tickets you need. The screen then shows a clear breakdown: Fare + ₩500 Deposit = Total. (In the example below, two child tickets show a fare of ₩1,100, a deposit of ₩1,000, and a ₩2,100 total.) Don’t worry about the deposit — you get it back at the end.

Step 4. Pay and collect your card

Insert cash (bills and coins) or pay by card, and the machine issues your ticket. It shows “Issuing…” and then a completed screen with your change. Your single-journey ticket is a thin yellow plastic card, not a paper ticket.

Step 5. This is your ticket

Keep this yellow card safe — you’ll tap it going in and coming out, and you’ll need it to reclaim your deposit. The back explains how to use it.

Riding the train

Tap in at the gate

At the fare gates, tap your card on the round reader on top of the gate and walk through. Do the same to tap out when you exit at your destination. If the gate beeps red, your card didn’t read — step back and tap again.

On board

Trains are clean, air-conditioned, and have clear English announcements before each stop. Screens and maps above the doors show the next station and which side will open. Free Wi-Fi is available on most trains.

Bicycle spaces on the train

Look at the ends of each car and you’ll spot a dedicated bicycle area, marked with a bicycle symbol and fitted with metal rails to hold your bike steady. You can bring a full-size bicycle on the subway on weekends and public holidays — board the first or last car and secure it in these racks. Folding bikes (folded and bagged) are allowed any day, any time. Rules can vary by line, so check the current signage before you travel.

Priority and courtesy seats

The pink seats are reserved for pregnant passengers, and the seats at each end of the car are priority seats for the elderly, disabled, and passengers with small children. Please leave these free even if the car is crowded. Other etiquette: keep phone calls quiet, let people off before you board, and avoid eating strong-smelling food.

After your trip: get your ₩500 deposit back

This is the step tourists forget. After you tap out and exit, look for a machine labeled “Deposit Refund Device” (usually right by the exit gates). Insert your yellow single-journey card and it returns your ₩500 deposit in coins. If you used a rechargeable card, there’s nothing to refund.

How fares work

Seoul uses distance-based pricing. The base fare covers the first 10 km; after that a small amount is added for each additional 5 km, so a long cross-city trip costs a little more than a short hop. With a transit card, transfers between subway lines and buses are free within 30 minutes, which makes cards much better value than single-journey tickets if you change lines. A useful 2026 update: on some lines you can re-enter the same station within 15 minutes without paying the base fare again (handy if you exit by mistake).

Quick tips for visitors

• Download Naver Map or KakaoMap for accurate subway routing (Google Maps transit is limited in Korea).
• A T-money or WOWPASS card saves money and time if you’ll ride more than a couple of times.
• Keep your single-journey card until after you refund the deposit.
• Stand on the right on escalators; let passengers exit before boarding.
• Rush hours (roughly 07:30–09:00 and 18:00–19:30) are very crowded — avoid if you have luggage.

Frequently asked questions

How much is a single Seoul subway ride?
The adult base fare is about ₩1,550 with a transit card and ₩1,650 for a single-journey ticket, plus a refundable ₩500 deposit on single-journey tickets. Longer trips cost a little more.

How do I get the ₩500 back?
After you exit, insert your yellow single-journey card into a “Deposit Refund Device” near the gates and it returns the ₩500 in coins.

Can I use a foreign credit card?
You can pay for single-journey tickets with cash or card at the machines, but Climate Card recharges accept Korean-issued cards only. A rechargeable T-money or WOWPASS card avoids this issue.

Is the Seoul subway in English?
Yes. Machines, signs, maps, and train announcements are all available in English, and stations have both names and numbers.

What are the subway operating hours?
Roughly 05:30 to around midnight, depending on the line and direction. Check the last-train times if you’re out late.
