Old and new Seoul face each other across the Han River, tied together by one of the world's largest metro networks.
Seoul city bus (시내버스)
Overseas contactless cards don't work on the buses - a T-money card is effectively mandatory. Cash is fading too: 183 routes are now cashless. And tap off as you leave - that is what unlocks the transfer discount.

How to ride
- 1Get a T-money cardBuy a T-money card at any convenience store - CU, GS25, 7-Eleven - and top up with cash.
- 2Read the bus colorsBlue = trunk (long-haul), green = feeder/maeul, red = expressway to suburbs, yellow = loops (now rare), N = night.
- 3Plan your route in NAVER MapPlan your route in NAVER Map, then watch the electronic arrival screens at the stop.
- 4Flag it down, board at the front, tapRaise a hand or your bus may sail past. Board at the front, tap the reader, and grab a handle - drivers pull away fast.
- 5Press the bell, tap off at the rear doorPress the red bell before your stop, then tap off on the rear-door reader as you leave.
- 6Transfer within 30 minutes, almost freeTap the next bus or subway within 30 min of tapping off (60 min 9pm-7am) and it counts as one trip - same route twice doesn't.
- 7After midnight, catch an N "owl" busLate at night, switch to the N routes. They work like daytime buses - just check arrivals in the app, since they run less often.

Heads-up
-
Skip the tap-off and the transfer discount is gone
Skip the tap-off and you lose the transfer discount - and distance-based fares can't settle correctly.
-
A full red express bus may not take you
Red express buses ban standing on expressway sections - a full bus may simply not take you.
