Seoul's public transport network ranks among the most efficient in the world, and getting around the city comes down to picking the right mix of subway, bus, and taxi for each part of the day. A single T-money card covers nearly every mode of transport in this guide, making it the first thing worth sorting out after landing. Booking flights into Seoul, whether through Incheon or Gimpo, connects directly to the city's rail network from the terminal. Both airports link into the same subway and express-rail system, so the choice of which one a flight lands at mainly affects how long the first transfer into the city takes.

The subway's base fare runs 1,550 won with a T-money card or 1,650 won for a single-journey paper ticket, covering the first 10 kilometres before adding 100 won for every additional 5 kilometres. Teenagers aged 13 to 18 pay 900 won and children 6 to 12 pay 550 won. A T-money card itself costs 2,500 to 4,000 won to purchase, sold at convenience stores and subway kiosks citywide, including both Incheon and Gimpo airports, with the card price separate from whatever balance gets loaded onto it. Since March 2026, more than 440 kiosks across 273 subway stations accept foreign Visa or Mastercard for top-ups, carrying a 3.7 percent service fee, and free transfers between subway and bus apply within 30 minutes of tapping out. The same card also works on buses and subways in Busan, Incheon, and several other Korean cities, making it worth keeping rather than discarding at the end of a Seoul-only trip if further travel around the country is planned.

The subway network spans more than 20 numbered and coloured lines, with station names displayed in Korean, English, and station numbers on every platform sign, making transfers straightforward even without reading Hangul. Line 2, the green circular line, connects many of the city's busiest districts and tends to be the one visitors ride most during a typical trip. Platform screen doors on most lines add a layer of safety and keep waiting areas relatively calm even during rush hour. Digital displays above each platform count down the minutes to the next train in both directions, useful for deciding whether to wait or take a connecting bus instead. Most stations also post simplified transfer maps near the platform exits, pointing toward the nearest connecting line without needing to pull up a phone map first.

Seoul's colour-coded bus system runs blue and green trunk and branch routes for 1,550 won with T-money or 1,650 won cash, yellow village buses for a cheaper 1,200 won, and red wide-area express buses for 3,000 won. Night buses, running roughly 11:30pm to 6am, cost 2,500 won and cover routes across the city once the regular network winds down for the evening. Buses and subway trains share the same transfer discount, so switching between the two within the 30-minute window doesn't add extra cost.

Standard taxis start at 4,800 won for the first 1.6 kilometres, adding 100 won for every 131 metres after that. Deluxe and jumbo taxis, suited to larger groups or extra luggage, start from 7,000 won, while international taxis with English-speaking drivers start from 8,000 won using the same distance-based increments as the standard fleet. Night surcharges apply on top of the base fare, adding 20 percent between 10pm and 11pm and 40 percent from 11pm through 2am.

The direct express service runs nonstop from Incheon to Seoul Station in around 43 minutes from Terminal 1 or 51 minutes from Terminal 2, priced between 11,000 and 13,000 won depending on whether the ticket is booked online in advance or purchased at the counter. The all-stop commuter version follows a distance-based fare similar to the subway, running up to roughly 5,350 won depending on the destination station, and takes considerably longer but costs a fraction of the express fare. Seoul Station also connects directly into two subway lines, so the express train effectively drops arriving travellers straight into the rest of the transport network without a separate transfer leg.

Ride-hailing apps operate throughout Seoul and are genuinely usable by foreign visitors now, with English interfaces and no Korean bank account required to book a ride. One dominant local app handles the bulk of bookings, which can mean slightly longer wait times on smaller competing apps during busy periods, but all options accept cash, card, or T-money for payment. Fares track closely with metered taxi pricing, so the main advantage over flagging a cab on the street is being able to set a destination in English from the start and see an estimated fare before confirming.

Seoul's transport network covers the city thoroughly enough that a car isn't necessary for most visits, but a car rental opens up day trips beyond the subway's reach, such as the DMZ border area, Nami Island, or the mountain trails outside the city limits. An international driving permit is required alongside a valid home licence, and driving in central Seoul itself can be slower than the subway during peak hours, so renting mainly pays off once the itinerary moves past the city's transit coverage. Parking at popular day-trip destinations outside Seoul tends to be more straightforward than parking within the city centre.

With over 100 million users across Southeast Asia, Traveloka brings flights, hotels, and activities for a Seoul trip together in the Traveloka app, alongside current Traveloka promotions worth checking before locking in dates. Reserve an airport transfer from Incheon or Gimpo for arrival day, then let the T-money card handle the rest of the city from there.
