Transportation

Korean public transport is the strongest practical argument for not owning a car. It is fast, punctual, clean, cheap and goes almost everywhere. The one habit to learn on day one is tagging your card both on and off - because the transfer discount, which is where the real saving is, only works if you tag out.

The transport card

Buy one at any convenience store and load it with cash. It works on subway, bus and taxi nationwide, and the balance is refundable.

Two card systems cover the country and both are accepted almost everywhere. Many Korean credit and debit cards also carry a transit function, which is what most residents end up using once their bank account works, and some phones support it directly.

Tag on when boarding and tag off when leaving. Failing to tag off costs you the transfer discount on your next leg and can trigger a penalty fare. It is the single most common mistake new arrivals make, every day, for about a month.

The transfer discount, which is the point

Within a time window after tagging off, your next bus or subway leg is free or heavily discounted, across several transfers. A journey involving a bus, a subway and another bus can cost close to a single fare.

This is why the card beats cash by a wide margin and why tagging off matters. Distance-based supplements apply on longer subway journeys, so a cross-city commute costs more than a short hop, but the increments are small.

Passes and refund schemes

Worth checking before you settle into paying per ride, because Korea has introduced several schemes that cut regular commuting costs substantially:

	What it does
National transit refund scheme	Refunds a percentage of your monthly spend once you pass a trip threshold
City unlimited pass	A flat monthly fee for unlimited travel within a metropolitan area
Commuter and youth rates	Reduced percentages for younger riders and some categories

Eligibility, thresholds and whether a residence card is required have changed since these launched, and they differ by city. Confirm the current terms and whether foreign residents qualify rather than relying on an article, then register once and stop thinking about it.

Rail between cities

High-speed rail makes Korea small: the far south is a few hours from Seoul, and two operators run competing services on the main corridor. Below that sit limited-express and all-stop trains, slower and cheaper.

Book ahead in high season and around the two big holidays, when seats sell out as soon as they are released. Reserved seats are worth it; standing tickets exist and are unpleasant on a long run. Note that the rail passes marketed to foreigners are generally for short-stay visitors rather than residents, so as a resident you buy ordinary tickets.

Express coaches cover routes rail does not, are comfortable and cheap, and run frequently.

Taxis

Inexpensive by developed-country standards and easy once you have a Korean phone number, because the ride-hailing apps that everyone uses key off it. Street hailing works too.

Expect a late-night surcharge, and expect demand to exceed supply after the last train on a weekend, which is when the apps start adding call fees. Paying with a transport card or credit card in the cab is normal. Keep your destination written in Korean on your phone; many drivers speak little English and an address typed into the app solves it anyway.

Commuting, realistically

Transport is cheap enough that most residents choose a home by commute time rather than by fare. In the capital region the subway is usually faster than driving at peak, and the trains are crowded in a way that is worth experiencing before you commit to a two-transfer commute.

Shared bikes and scooters cover the short first and last leg, and many stations have bike parking. Walking is pleasant and the cities are built for it.

Getting to and from the airports

Worth knowing before your first trip out of the country, because the options differ a lot in cost.

A direct airport rail link runs into the capital, and limousine coaches stop at hotels and major junctions across the city, which is usually the easier option with luggage. Both are a fraction of a taxi fare. For an early departure there are also late-night coach services, and the airports themselves are comfortable enough to arrive at early.

Allow more time than seems necessary during the two big holiday periods, when the roads to the airport jam. Foreign tourists covers arrival from the other direction, and lifestyle covers the holiday weeks that cause it.

Accessibility and luggage

Subway stations have lifts and tactile guidance, though older stations can mean a long detour to find the accessible route. Large suitcases are awkward at rush hour; station lockers are widely available and cheap, and same-day luggage delivery services exist between airports and hotels.

Where this goes wrong

• Not tagging off. It costs you the transfer discount and can bring a penalty.
• Paying cash. You lose transfers entirely.
• Ignoring the refund and pass schemes if you commute daily.
• Booking holiday-period rail late. They go the day they are released.
• Assuming a tourist rail pass applies to you. As a resident it generally does not.
• Relying on English with a taxi driver rather than an address in Korean.

Where to go next

Essential living covers the card as part of your first week, and vehicle and mobility covers the case for driving if public transport genuinely will not do.
