Getting Around Seoul
Seoul's transportation systems are regarded as among the best and most advanced in the world. The city is very well connected by subway and bus services, and is also very supportive of pedestrian foot travel. The high population density means that most of the city's population now relies on public transportation for its convenience and low cost.
The Subway and Metro Network
Seoul's subway system is one of the busiest in the world, with over 8 million passengers daily. There are nine numbered lines plus a smattering of named suburban lines that interconnect every district and the surrounding area. The system is highly regarded for its efficiency, ease of navigation, timeliness, and the shops and attractions present within stations themselves. All signs in the subway system are displayed in Korean and English, with Japanese and Mandarin also visible in some stations.
The numbered lines are distinguished by different colors, making navigation straightforward. In addition to the numbered lines, there are several named suburban lines serving the wider metropolitan area. Gimpo Airport is particularly well-connected, with services on Line 5, Line 9, Gimpo Goldline, and the Seohae Line, in addition to the AREX airport rail service.
Buses
Seoul has an extensive bus network with four types of buses, each serving different routes:
- Red "regional" buses connecting Seoul to inner suburbs
- Blue "mainline" buses acting as supplementary mainline transportation
- Green "branch-line" buses extensively covering certain areas
- Yellow "loop-line" buses circling around certain areas
For travel outside the city, Seoul has major intercity bus terminals connecting to cities throughout Korea, including Seoul Express Bus Terminal and Central City in Banpo-dong, Seocho-gu, Seoul Nambu Terminal, and Dongseoul Bus Terminal in Gwangjin-gu.
Taxis and Ride-Hailing
Two tiers of taxis operate in Seoul. Regular taxis are typically white, silver, or yellow in color. Deluxe taxis (also called "Model Taxis") offer higher service standards. International taxis are also available with English-speaking drivers. Many taxis accept the Tmoney transportation card, which is indicated by a Tmoney logo on the vehicle.
Walking
Seoul is very supportive of pedestrian foot travel. The city's street and subway signage is usually written in both English and Korean, making navigation easier for visitors. Modern address systems using street names have replaced older numbering methods, further simplifying wayfinding throughout the city.
Getting from the Airports to the City
Incheon International Airport
Incheon International Airport, located on Yeongjong Island in neighboring Incheon, handles almost all international flights. The airport is connected to Seoul by the Incheon International Airport Railroad (A'REX), which departs from a station in the Transport Centre adjacent to the main terminal building.
The A'REX offers two service options. Express trains run every 40 minutes to Seoul Station, taking 43 minutes and costing ₩9,000, with WiFi available on board. These require reservations and accept credit card payments, with advance purchase possible. All-stops services run every 6 minutes, taking 53 minutes and costing ₩4,750; these are unreserved trains accepting only cash or T-money payment. Express and all-stops trains depart from different platforms with separate ticket booths.
The airport is also served by the Incheon Airport Maglev. For passengers with significant luggage or heading to southern parts of Seoul such as Gangnam, airport buses are an alternative option. Direct taxis from Incheon to Seoul cost approximately ₩50,000–70,000 for regular and deluxe taxis respectively.
Gimpo Airport
Gimpo Airport, formerly Seoul's only airport, now primarily serves domestic flights and limited international routes to Tokyo (Haneda), Osaka (Kansai), Beijing (Capital), Shanghai (Hongqiao), and Taipei (Songshan). The airport is more centrally located than Incheon.
Gimpo is accessible via the A'REX line from Incheon Airport and Seoul Station, as well as via subway lines 5 and 9. All these lines connect to Line 2, which runs in a large circle through Seoul. Line 9, Seoul's first privately operated subway line, also offers express train services. Subway fares from Gimpo range from ₩1,000–2,100 depending on distance, with discounts available using T-money cards. A taxi to central Seoul costs approximately ₩30,000.
Paying for Transportation
The Tmoney transportation card is the most common payment method for public buses and subways in Seoul. Cards are purchasable for ₩2,500 from machines at subway stations and most convenience stores. Money is loaded onto the card, which is then tapped at sensors when entering or exiting buses or subway stations, with the appropriate fare automatically deducted.
International tourists have an alternative: the KOREA TOUR CARD, purchasable for ₩4,000, which works similarly to Tmoney but also provides discounts to many popular tourist attractions.
Transportation cards are not required; cash and credit cards can be used to buy individual tickets, though this requires a new ticket for each journey. Transportation cards offer slight discounts on fares and allow up to four transfers between Seoul subways and buses with no additional charges.
For frequent train travel, foreign visitors can purchase a Korea Rail Pass from KORAIL (Korea Railroad Corporation), allowing unlimited rides on supported trains within the purchased timeframe.
Regional Train Services
As South Korea's capital, Seoul is the northern terminus for most intercity and high-speed rail services. The city has multiple major railway stations: Seoul Station serves trains heading southeast toward Busan, Daegu, and Changwon, as well as some eastbound services; Yongsan Station is the main terminus for southwest routes toward Mokpo, Gwangju, and Yeosu; Cheongnyangni Station serves eastbound services including all KTX trains to Pyeongchang, Gangneung, Donghae, and Andong; and Suseo Station in the southwest serves SRT trains. Several other stations including Yeongdeungpo, Sangbong, and smaller stations like Oksu and Wangsimni also provide regional rail connections. Reservations are mandatory for all KTX services and are included in ticket prices; high demand, particularly on the Seoul-Busan route on weekends, means booking at least a week ahead may be necessary.
