Getting from Gimpo Airport (GMP) to Seoul

Gimpo International Airport is about 18 km west of central Seoul. It is significantly closer to the city than Incheon (ICN) and has excellent public transport connections. A pre-booked private transfer costs around KRW 55,000–80,000. A regular taxi is metered on the Seoul city tariff — KRW 4,800 for the first 1.6 km, then KRW 100 per 131 m (and KRW 100 per 30 seconds whenever the cab is crawling) — which puts the 18 km into central Seoul at roughly KRW 20,000–25,000 once slow traffic and any expressway toll are counted. The subway (Lines 5, 9, or AREX) costs KRW 1,550–1,850 and takes 25–40 minutes to most central areas.

Gimpo handles primarily domestic flights and some regional international routes (Japan, China, Taiwan). If you are flying into Seoul from one of these destinations, GMP is often the more convenient airport.

Gimpo is a compact, well-organized airport. International arrivals exit through the first floor of the international terminal. Immigration is typically fast — 10–20 minutes for most nationalities.

The arrivals hall has convenience stores, a tourist information desk, and T-money card vending machines. Buy a T-money card immediately — it works on all subways, buses, and even taxis across Seoul. The card itself costs a few thousand won (the price varies by retailer and card design) and you load credit as needed.

Free Wi-Fi is available throughout the airport. You can also rent a pocket Wi-Fi device or buy a prepaid SIM card from the KT or SK Telecom booths in the arrivals area.

KRW is what you actually pay; euro equivalents move with the exchange rate, so convert at the rate on the day rather than trusting a printed figure.

The subway is genuinely excellent. Gimpo Airport station connects to Line 5 (purple), Line 9 (gold), and the AREX line. Line 9 express goes to major business districts. The AREX connects to Seoul Station in about 20 minutes. Trains run from approximately 5:30 AM to midnight.

Regular taxis (orange/silver) are metered, honest, and easy to find outside the terminal. The Seoul tariff is KRW 4,800 for the first 1.6 km, then KRW 100 per 131 m (and KRW 100 per 30 seconds whenever the cab is crawling). Language can be a barrier — have your hotel address written in Korean. Deluxe taxis (black) are larger, more comfortable, and drivers often speak some English; they run on their own higher tariff (KRW 7,000 for the first 3 km, then KRW 200 per 151 m), which works out roughly 50% more on an airport-length trip.

Airport limousine buses run to major hotel districts including Myeongdong, Gangnam, Hongdae, and Itaewon. They are comfortable with luggage space, but slower than the subway due to traffic.

There is no fixed airport taxi price in Seoul — you pay whatever the meter reads on the city tariff above. What that comes to depends on distance and how much of the trip is spent stationary, so treat the figures below as what the tariff implies rather than a quoted price.

Subway fares follow the published city scale: KRW 1,550 with a transit card for the first 10 km, then KRW 100 per additional 5 km (cash tickets cost KRW 100 more). Seoul does not run one flat night rate. On a regular sedan the surcharge is 20% from 22:00-23:00, 40% from 23:00-02:00, and 20% again from 02:00-04:00 — so the most expensive time to ride is just after 23:00, not after midnight. Deluxe taxis take a flat 20% from 22:00 to 04:00. A further 20% applies to trips beyond the city limits. Expressway tolls, if the driver uses one, are added to the meter.

The subway stops running around midnight. If your flight lands after 11 PM, you will need a taxi, ride-hailing app (Kakao T), or pre-booked transfer.

Late-night taxis are available, but the surcharge is tiered rather than flat. Seoul does not run one flat night rate. On a regular sedan the surcharge is 20% from 22:00-23:00, 40% from 23:00-02:00, and 20% again from 02:00-04:00 — so the most expensive time to ride is just after 23:00, not after midnight. Deluxe taxis take a flat 20% from 22:00 to 04:00. A further 20% applies to trips beyond the city limits. In practice a metered ride into central Seoul that runs about KRW 22,000 by day is roughly KRW 26,000 in the 22:00-23:00 band and about KRW 31,000 between 23:00 and 02:00. The taxi rank outside Gimpo is well-lit and staffed, so safety is not a concern.

A pre-booked transfer is the most comfortable option for late arrivals — your driver waits inside the terminal regardless of delays.

The subway is efficient but not ideal with multiple suitcases and children. Stations have elevators but they can be hard to find, and rush-hour trains are extremely crowded.

For families, a pre-booked transfer or deluxe taxi is the practical choice. Regular taxis are Hyundai Sonata-sized sedans — fine for two people with luggage but tight for a family of four. Deluxe taxis (black) and pre-booked transfers offer larger vehicles.

South Korea requires child car seats for children under 6 years old. Regular taxis do not carry them. Request a child seat when pre-booking your transfer.

For pre-booked transfers, drivers wait in the international arrivals hall on the first floor, usually near the exit doors with a name board.

For taxis, exit the arrivals hall and follow the signs to the taxi stand — it is directly outside, about a 30-second walk. Taxis queue in an organized line and dispatchers help match you to the next available car.

For the subway, follow signs to "Metro" or the specific line number. The station is connected to the terminal via an underground walkway — about a 5-minute walk from arrivals.

Choose the subway if: you are traveling solo or as a couple with manageable luggage, arriving between 5:30 AM and 11 PM, and want the cheapest and often fastest option.

Choose a regular taxi if: you have moderate luggage, want door-to-door service, and are comfortable with a metered fare.

Choose a pre-booked transfer if: you are traveling with family, arriving late at night, have heavy luggage, or want guaranteed English-speaking service and a fixed price.

Choose the airport bus if: you want comfort at a moderate price and your hotel is near one of the bus route stops.
