Subway, buses, taxis and airport transfers
A T-money card works on most subways, buses, convenience-store top-ups, and many taxis. Buy one at a convenience store or subway station, then charge it with cash at a machine or counter.
It saves time because you do not need to buy a separate ticket for each subway or bus ride.
Korean subway stations can be large, but line colors, station numbers, and exit numbers make transfers manageable. Follow the line color first, then confirm the direction by the final station name.
Before leaving the platform, check the exit number on your map app because the wrong exit can add a long walk.
Buses can save walking time in neighborhoods like Bukchon, Namsan, or riverside areas. Tap your transit card when boarding and tap again when getting off.
If you are unsure, stand near the front screen and watch the next-stop display.
Taxi drivers may not recognize English place names, so save the Korean address or use a taxi app when possible. Hotel names and landmark names work better if shown in Korean.
Late-night taxi demand can rise quickly after subway service ends, so allow extra time.
From Incheon Airport, the AREX train is usually the clearest route into Seoul. The express train is comfortable for Seoul Station, while the all-stop train can be better for Hongdae or Gimpo Airport.
Check whether your hotel is closer to a subway line, airport bus stop, or taxi-friendly road before deciding.
