Korea Public Transportation in Seoul: Every Way to Get Around (2026)
Korea public transportation is genuinely one of the best in the world — clean, affordable, and easy to navigate even on your first day. Seoul alone has a subway network that puts most major cities to shame: 23 lines, thousands of stations, trains every two to three minutes during peak hours, and fares starting at around ₩1,400. Buses fill in the gaps the subway doesn’t reach, taxis are cheap by international standards, and a public bike system lines the entire Han River.
The whole network runs on a single card — T-Money — which you can pick up the moment you land at Incheon Airport. One tap gets you on a subway, a bus, or a bike. Transfers between most modes are free within 30 minutes.
Whether you’re heading to a palace, a night market, or a hiking trail on the edge of the city, you’ll get there without breaking a sweat — and probably faster than you expected. Here’s every option, broken down.
Seoul Subway
The Seoul Metro runs 23 lines and covers virtually every corner of the city. Trains run from around 5:30 AM to midnight, with signs in Korean, English, Chinese, and Japanese. Line 2 (the green circle line) connects most major tourist spots — Hongdae, Gangnam, Seongsu, and Jamsil. Line 4 is your go-to for Myeongdong and Dongdaemun. It’s the fastest and most reliable way to get around, and locals and visitors alike depend on it daily. For line-by-line breakdowns, exit number tips, and rush hour strategy, see our full guide.

City Buses
Seoul’s buses are color-coded by route type, which makes them easier to navigate than they look.
Your entire Seoul bus guide, captured in one traffic jam.
- Blue — Long-distance routes crossing the city (간선버스)
- Green — Short routes connecting neighborhoods to subway stations (지선버스)
- Yellow — Circular routes within a district (순환버스)
- Red — Express buses between Seoul and surrounding suburbs (광역버스)
- Town Bus — Small neighborhood buses weaving through side streets to the nearest subway station. Route numbers include the district name (e.g. 성북01, 종로08). Same T-Money tap-in applies.
Tap your T-Money card when you board and again when you exit. Press the stop button before your destination — drivers won’t stop unless they see the signal. Enter through the front door, exit through the back.

Taxi
Taxis in Seoul are metered, plentiful, and reasonably priced by international standards — a short ride within the city typically costs ₩5,000–10,000. For foreigners, booking through an app is the easiest option since it handles language barriers and payment automatically. Kakao T is the most widely used, with an English interface and no Korean phone number required. Late-night rides after the subway closes are common and safe.

Seoul Bike (따릉이)
Ttareungi is Seoul’s public bike-share system, with docking stations across the city and along the Han River. It’s affordable (around ₩1,000 per hour), easy to rent via app as a foreigner, and one of the best ways to explore riverside parks and flat neighborhoods like Yeouido or Mapo. A helmet is included at each station.

Hangang River Bus
Seoul’s newest transit option connects key spots along the Han River by boat. It launched in 2024 and now runs between Jamsil, Yeouido, Mapo, and other riverside stops. It’s faster than it sounds for certain routes, genuinely scenic, and unlike anything else in the city. A great option if you’re already spending time near the river or want a different perspective on Seoul.

Korea Public Transportation Tip: T-Money Card
Almost everything above — subway, bus, and bike — runs on the T-Money card system. Pick one up at Incheon Airport or any convenience store (CU, GS25, 7-Eleven), load it with cash, and tap in and out at every stop. It’s cheaper than single-ride tickets and unlocks free transfers between buses and the subway within 30 minutes. One card covers your entire trip.
