Seoul Transportation Guide: Subway, Bus, Taxi & T-Money Card

Seoul has one of the best public transportation systems in the world. Clean, punctual, cheap, and fully bilingual — getting around is never a problem once you understand the system. This guide covers everything from airport transfers to late-night taxis.

Quick Summary for First-Time Visitors

• Get a T-money card at the airport immediately after landing
• Use the subway for most travel — fast, cheap, and easy
• Use Kakao T for taxis — never flag one blindly
• Use Naver Maps or KakaoMap instead of Google Maps for navigation
• Tap OFF when exiting buses — or you overpay every time

The T-Money Card: Get This First

The T-money card is a rechargeable contactless card that works on subways, buses, and some taxis across Korea.

Why you need it:

• Single-use tickets cost ₩200 more per ride
• Seamless transfers between subway and bus within 30 minutes
• Works at convenience stores (CU, GS25, 7-Eleven) for small purchases
• No need to count change or buy tickets each time

Where to buy:

• Any convenience store in Korea (including Incheon Airport arrivals)
• Subway station ticket machines
• Cost: ₩2,500 (deposit, refundable) + however much you load

How to use:

• Tap the yellow card reader when entering AND exiting
• Top up at any subway station machine or convenience store
• Minimum load: ₩1,000 — load ₩20,000–₩30,000 to start

WowPass — T-Money + Debit Card in One

WowPass combines a T-Money transit card and a prepaid debit card in one physical card. You can use it on all subways and buses, pay at shops and restaurants, and load Korean Won from a foreign card at WowPass kiosks (available at major airports and tourist areas). A practical upgrade for travelers who want to minimize cash.

Seoul Subway: The Backbone

Seoul's subway has 22 lines covering the entire metropolitan area. For tourists, Lines 1–9 and the Gyeongui-Jungang Line cover everything you need.

Key lines for tourists:

Fares:

• Base fare: ₩1,400 (first 10km)
• Each additional 5km: +₩100
• Most tourist trips: ₩1,400–₩2,000

Hours: Approximately 5:30am–midnight (last trains vary by line — check the schedule at stations)

Navigation: Google Maps works for basic subway routes, but it is not fully reliable in Korea. For the best results, use Naver Maps or KakaoMap — both provide more accurate routes, real-time updates, and walking directions tailored for Korean transit.

From Incheon Airport to Seoul

AREX (Airport Railroad Express) — Recommended

Direct train from Incheon Airport to Seoul Station: 43 minutes, ₩9,500.

• Departures: Every 30 minutes (Express) or every 6–12 minutes (All-stop)
• All-stop train: Cheaper (₩4,950) but takes 66 minutes and stops at Gimpo Airport
• From Seoul Station, transfer to subway to your hotel

📍 AREX Departure: Incheon International Airport Station (B1 floor, Terminals 1 & 2)

Airport Limousine Bus

Direct buses to major hotel areas and neighborhoods. More luggage space than the train.

• Price: ₩15,000–₩18,000
• Journey time: 60–100 minutes depending on traffic
• Best for: If you're staying in Hongdae, Gangnam, or Myeongdong (direct buses available)
• Look for the bus number corresponding to your destination on the departures board

Taxi from Airport

Convenient for groups with lots of luggage, but the most expensive option.

• Price: ₩65,000–₩85,000 to central Seoul
• Journey time: 60–80 minutes
• Always use the official taxi queue on the arrivals floor — avoid drivers who approach you inside the terminal
• Use Kakao T app to pre-book for a fixed metered fare and no surprises

City Buses

Buses fill the gaps where the subway doesn't reach. They're also cheaper for some routes.

How to use:

• Tap T-money on boarding AND alighting
• Transfers to/from subway within 30 minutes are free (counted as one journey)
• Routes in Korean — use Naver Maps or KakaoMap to check the route number

Bus types:

• Blue (간선): Main city arteries
• Green (지선): Local neighborhood buses
• Yellow (순환): Inner city loop routes
• Red (광역): Express buses to suburbs

Always Tap OFF on Buses

This is the most important transit tip most tourists miss. When you tap your T-Money card on boarding AND tap again when exiting, the system calculates the exact distance and deducts only what you owe. Skip the exit tap and you pay the maximum flat rate every time — plus lose your free transfer.

Taxis

Seoul taxis are reliable and affordable by international standards.

Kakao T app — Korea's ride-hailing app (like Uber). Works on most foreign credit cards. Shows fare estimate before booking. Recommended over street-hailing for all tourists.

Types:

• General (일반): Silver/white/orange cabs — base fare ₩4,800
• Deluxe (모범): Black cabs — base fare ₩7,000, higher quality drivers
• Kakao Black: Premium private cars via the app

Fare guide:

• Short hop (2–3km): ₩5,000–₩7,000
• Cross-city ride: ₩12,000–₩20,000
• Airport (Incheon): ₩65,000–₩85,000

Night surcharge: 20% added from midnight–4am

Taxi Safety Tips

Avoid unlicensed or aggressively soliciting drivers, especially inside airports and near popular tourist areas at night. Always use Kakao T or official taxi stands to ensure a metered, safe ride. If you must flag a taxi on the street, confirm the meter is running before the car moves.

Licensed standard taxis are orange or silver — these are safe and metered. Premium taxis (모범택시) are black with a blue or green roof light — legitimate and higher quality. If a driver approaches you inside the airport or quotes a flat price without a meter, walk to the official taxi queue instead.

Getting Around Without a Smartphone

Possible but harder. Buy a paper map from tourist information centers at major subway stations. Station names are posted in English on all platforms. Most taxi drivers know major landmarks by name in English.
