How to Use the Seoul Subway: Tourist Guide (2026)
Why the Seoul Subway Is the Best Way to Get Around
As a Korean who has lived in Seoul for years, I can tell you this: the Seoul subway is the easiest, cheapest, and most reliable way to travel around the city. It covers virtually every major tourist destination, runs on time, and costs a fraction of what taxis charge.
But if you've never used it before, it can feel overwhelming. The signs are in Korean (though most have English too), the transfer stations are massive, and the ticketing system is different from what you're used to back home.
Don't worry. This guide walks you through everything step by step — from buying your first transit card to navigating transfers like a local.
Step 1: Get a T-money Card (Your Must-Have Transit Card)
The T-money card is a rechargeable transit card that works on subways, buses, and even taxis across South Korea. Think of it as Korea's version of London's Oyster card or Tokyo's Suica.
Where to Buy
Convenience stores (CU, GS25, 7-Eleven) — available at every subway station and throughout the city. Cost: around 2,500 KRW (~$2 USD) for the card itself
Incheon Airport — buy one immediately after landing at any convenience store in the arrivals hall. See our Incheon Airport to Seoul transfer guide for detailed airport transit options
Subway station vending machines — some stations have machines that sell T-money cards
How to Recharge
Top up your T-money card at any convenience store or the yellow/blue recharge machines inside subway stations. These machines have an English language option — just press the flag icon on the screen.
Pro tip from a local: Load at least 20,000 KRW (~$15 USD) to start. A single subway ride costs 1,400-2,000 KRW depending on distance, so 20,000 KRW covers roughly 10-14 rides — enough for 3-4 days of exploring.
Can You Use Your Phone Instead?
Yes! If you have a compatible smartphone, you can use mobile T-money through apps like Samsung Pay or the T-money app. However, this can be tricky to set up with a foreign phone, so I recommend just getting the physical card — it's simpler and works perfectly.
Step 2: Understanding the Subway Map
Seoul's subway system has over 20 lines and 700+ stations, but don't let that scare you. As a tourist, you'll mainly use these lines:
Line | Color | Key Tourist Spots |
|---|---|---|
Line 1 | Dark Blue | Seoul Station, City Hall, Jongno, Dongdaemun |
Line 2 | Green (Circle Line) | Hongdae, Gangnam, Jamsil (Lotte World), Euljiro |
Line 3 | Orange | Gyeongbokgung, Anguk (Bukchon), Express Bus Terminal |
Line 4 | Light Blue | Myeongdong, Dongdaemun, Seoul Station |
Line 6 | Brown | Itaewon, Hangang Park |
Gyeongui-Jungang | Teal | Hongdae, DMC, outskirts |
Each line is color-coded and numbered. You can view the full official map on the Seoul Metro website. Stations also have unique 3-digit numbers (e.g., Myeongdong is 424). Even if you can't read Korean, the numbers make it easy to confirm you're at the right station.
Step 3: Navigating the Station
Here's what to expect when you enter a Seoul subway station for the first time:
Entering the Station
Find the entrance — look for the subway logo (a circle with a number inside) or the large station signs. Most stations have 5-10 entrances numbered for easy reference
Go through the gates — tap your T-money card on the blue sensor pad at the turnstile. The gate opens automatically. The screen shows your remaining balance
Follow the signs to your platform — signs in Korean AND English show which direction each line goes. Look for your destination station or the terminal station name
Reading Platform Signs
Every platform has clear signage showing:
The line number and color
Direction — indicated by the terminal station name (e.g., "Towards Sindorim" or "Towards Jamsil")
Next train arrival time — displayed on electronic boards above the platform
Exiting the Station
When you arrive at your destination, tap your T-money card again at the exit gates. The fare is calculated based on distance traveled and deducted automatically. Simple!
Step 4: Mastering Transfers
Transferring between lines is free (within 30 minutes) and very common. Seoul's major transfer stations — like Jongno 3-ga, Seoul Station, Dongdaemun History & Culture Park — connect multiple lines.
How to Transfer
Get off the train
Follow the transfer signs (환승 / Transfer) — they show the line number and color you're transferring to
Walk to the connecting platform (some transfers are short, some are a 5-10 minute walk)
Board your next train — no need to tap your card again during transfers
Watch out: Some transfer walks are long! At Seoul Station, transferring between Line 1 and Line 4 takes about 5-7 minutes of walking. At Express Bus Terminal, the transfer between Line 3, Line 7, and Line 9 can feel like a maze. Don't rush — follow the signs and you'll get there.
Step 5: Use These Apps for Easy Navigation
You don't need to memorize the subway map. These free apps do the work for you:
Naver Map (Recommended)
Korea's most popular navigation app. Enter your destination in English, and it shows you the fastest subway route with real-time arrival info, transfer details, and exit number recommendations. This is the app most Koreans use daily.
KakaoMap
Another excellent Korean map app. Similar features to Naver Map. Some tourists prefer it because the English interface is slightly more intuitive.
Subway Korea (지하철)
A dedicated subway-only app. Shows the full map, calculates routes, and estimates travel time and cost. Great as a backup when you don't have data.
Local tip: Download Naver Map before your trip. Google Maps works in Korea for basic navigation, but it's missing transit details and walking directions that Naver Map handles perfectly. For more app recommendations, check out our guide to essential Korean apps every tourist needs.
Seoul Subway Etiquette: What Locals Expect
Koreans are generally polite and quiet on the subway. Here are the unwritten rules every visitor should know:
No eating or drinking — it's not illegal, but it's considered rude. Water is okay
Keep your voice down — loud conversations and phone calls are frowned upon
Priority seats are sacred — the seats at the end of each car (usually marked in a different color) are reserved for elderly, pregnant, and disabled passengers. Do not sit there even if they're empty. This is a big deal in Korea
Stand on the right side of escalators — left side is for walking
Let passengers exit first — wait on the sides of the door and let people get off before you board
Backpacks to the front — during rush hour, carry your backpack in front of you or put it between your feet
Fares, Hours, and Practical Info
How Much Does It Cost?
Distance | T-money Card | Single-Use Token |
|---|---|---|
Up to 10 km | 1,400 KRW (~$1.05) | 1,500 KRW (~$1.15) |
10-50 km | +100 KRW per 5 km | +100 KRW per 5 km |
50+ km | +100 KRW per 8 km | +100 KRW per 8 km |
Using a T-money card saves you 100 KRW per ride compared to buying single-use tokens. Over a week-long trip, that adds up!
Operating Hours
First train: Around 5:00-5:30 AM
Last train: Around 11:30 PM - 12:00 AM (varies by line and station)
Frequency: Every 2-3 minutes during rush hour, every 5-8 minutes at other times
Important: There is NO 24-hour subway service in Seoul. If you miss the last train, your options are night buses (owl buses), taxis, or Kakao T (ride-hailing app). Plan accordingly if you're out late!
Rush Hour Warning
Avoid the subway between 7:30-9:00 AM and 6:00-7:30 PM on weekdays if possible. Line 2 (the green circle line) is especially packed during these hours. If you must travel during rush hour, skip one or two trains and wait for a less crowded one.

Final Tips from a Local
Free WiFi is available on most subway trains and in stations — look for networks like "Seoul WiFi" or "T WiFi"
Coin lockers are available at major stations if you need to store luggage for a few hours
Restrooms are inside every station (before the gates) and are free and clean
Station numbers matter — when asking for directions, use the 3-digit station number instead of the Korean name. It's much easier to communicate
Most stations have platform screen doors for safety, so don't worry about accidentally stepping off the platform
If you're lost, look for the information booth (usually near the ticket gates). Staff often speak basic English
The Seoul subway might look complex on the map, but once you ride it a couple of times, it becomes second nature. For more official tourist information, the Korea Tourism Organization has helpful resources. It's clean, safe, affordable, and incredibly efficient. As a Korean, I'm genuinely proud of our subway system — and I'm confident you'll love using it too.
