From Incheon airport to the far corners
Getting Around Seoul
Ride the AREX train in from the airport, buy a T-money card, and use the subway for almost everything. Here's how the airport link, the metro, buses, taxis and the day-trip runs actually work.
Check dates and availability ↗Arriving: Incheon airport and the AREX train
Most international flights land at Incheon International Airport (ICN), which sits on an island well west of the city — roughly 50 kilometres out, so budget real travel time into the centre. The smoothest way in is the AREX (Airport Railroad Express): the express service reaches Seoul Station in around 45 minutes, while the cheaper all-stop commuter train takes about an hour and connects into the wider subway network en route. Limousine buses run to hotel districts across the city, and taxis are available but pricier for the distance. A smaller airport, Gimpo (GMP), closer to town, handles domestic and some regional flights. Pick up a T-money card at the airport before you head in — it works on the AREX all-stop train and everything after.
The subway — your default for everything
Seoul's subway is one of the best in the world and will be your main way around: fast, frequent, spotlessly run, inexpensive, and signed and announced in English as well as Korean. Lines are numbered and colour-coded, stations are numbered too, and app maps make transfers easy to plan. It reaches almost everywhere a visitor wants — the palaces, Myeongdong, Hongdae, Gangnam, Dongdaemun and the Han River parks are all a short walk from a station. Trains run from early morning until around midnight, so late nights out may need a taxi home. With a T-money card you just tap in and out; fares are distance-based and cheap. For getting around the city itself, you'll rarely need anything else.
The T-money card — tap for everything
A T-money card is the single most useful thing to buy on arrival. It's a rechargeable transit card that works across the subway, city buses and even taxis, and it also pays at convenience stores and many vending machines. Buy one at any convenience store — CU, GS25, 7-Eleven — or from station machines, then top it up with cash at the same machines as you go. Tapping in and out with T-money is cheaper than single tickets and gives you free or discounted transfers between subway and bus within a set window, which adds up over a few days. One card can't be shared through a gate by two people, so everyone in your group needs their own. Cash out any small remaining balance at a convenience store before you leave.
Buses and taxis — filling the gaps
The subway covers most of the city, but buses and taxis fill the gaps. City buses are extensive and cheap and reach spots between subway lines, though routes and stop announcements lean more Korean than the metro, so a map app helps a lot; tap on and off with T-money to get the transfer discount. Taxis are plentiful and reasonably priced by many visitors' standards — the Kakao T app is the local standard for hailing one, showing the fare and removing any language friction at the kerb, and it's worth setting up before you arrive. Taxis come into their own late at night once the subway has stopped, and for short hops with luggage. Between the metro, buses and app-hailed taxis, you can reach anywhere in Seoul without ever renting a car.
Getting to the DMZ and other day trips
The one journey you don't arrange yourself is the DMZ. Because its sites sit inside a restricted military zone, you can't drive or take a train up independently — access is only via an authorised guided day tour, which handles the transport and clears the checkpoint for you, with pickups typically at Hongdae or Myeongdong and your original passport required on the day. Gentler day trips are more DIY: Nami Island and the Gapyeong area, a couple of hours north-east, can be reached by intercity train and a shuttle, or on a packaged tour that bundles the transport with Petite France and the Garden of Morning Calm. For anything with a fixed early start, like the DMZ, confirm your pickup point and time from the booking the night before.
Walking, and how the neighbourhoods connect
Seoul is huge, but it's a city best explored as a series of walkable pockets linked by the subway. The old town knits together on foot beautifully — you can walk from Gyeongbokgung through Bukchon Hanok Village and down into Insadong without touching a train — and districts like Myeongdong, Hongdae and Insadong are made for wandering once you're there. What doesn't work is walking between neighbourhoods: the distances are deceptive and the city is hilly in places. So treat the subway as the connective tissue between pockets of walking. Namsan and N Seoul Tower are the exception to the flat-and-easy rule, reached by the Namsan cable car or an uphill walk through the park — wear proper shoes for that one.
A short practical kit
A few things smooth every trip here. Buy a T-money card at the airport and top it up with cash as you go. Download a Korea-capable map app and the Kakao T taxi app before you arrive, and set them up on airport wifi — some global map apps give patchy walking directions in Korea, so a local-friendly one saves frustration. Carry a little cash for markets, small stalls and topping up the transit card, though cards are widely accepted. Remember the subway stops around midnight, so plan a taxi home from late nights. And for the DMZ specifically, keep your original passport on you — it's checked at the border and the day cannot go ahead without it. None of it is complicated; all of it saves time.
