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.

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

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:

| Line | Color | Key Stops | |------|-------|-----------| | Line 1 | Dark blue | Seoul Station, Dongdaemun | | Line 2 | Green | Hongdae, Gangnam, City Hall | | Line 4 | Blue | Myeongdong, Dongdaemun | | Line 5 | Purple | Yeouido, Gwanghwamun | | Line 6 | Brown | Itaewon, Hapjeong | | Line 9 | Gold | Gimpo Airport, Express to Gangnam | | AREX | Blue | Incheon Airport → Seoul Station |

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 perfectly for Seoul subway navigation in English. Naver Maps is more accurate for walking directions.

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

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

Expensive but convenient for groups with lots of luggage.

• Price: ₩65,000–₩85,000 to central Seoul
• Journey time: 60–80 minutes
• Go to the official taxi queue on the arrivals floor (don't accept offers from men approaching you inside)

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 Google Maps 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

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 tourists.

Types:

• General (일반): Silver/white cabs — base fare ₩4,800
• Deluxe (모범): Black cabs — base fare ₩7,000, but 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

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.
