Seoul is known for its efficient, reliable, and extensive public transportation system. For both locals and tourists, navigating the city’s metro, buses, and taxis is a breeze once you get the hang of it. Whether you’re planning to explore cultural landmarks, shop in bustling districts, or discover hidden gems, getting around Seoul without a car is not only feasible but also convenient. This guide will provide you with everything you need to know about Seoul’s public transportation system, ensuring you make the most of your travels around the city.

1. Overview of Seoul’s Public Transportation System

Seoul boasts one of the most advanced public transportation networks in the world. The three main modes of transport are the Seoul Metro, city buses, and taxis. Additionally, for those who wish to explore nearby provinces, there’s the KTX (Korea Train Express) and express buses that connect Seoul to other major cities in South Korea.

The T-money card is your key to the entire system. This rechargeable card works across all forms of public transport, including buses, subways, and some taxis. It’s highly recommended for tourists, as it saves the hassle of purchasing single-trip tickets for each ride.

Benefits of Using Public Transportation in Seoul

• Cost-efficient: Public transportation in Seoul is incredibly affordable. A subway or bus ride typically costs between 1,250 and 1,350 KRW (about 1 USD), depending on the distance.
• Convenient: The metro and buses run frequently, and stations are well-marked in both Korean and English, making it easy to navigate even for first-time visitors.
• Eco-friendly: Using public transportation helps reduce traffic congestion and pollution in a bustling metropolis like Seoul.
• Widely connected: The network covers every corner of Seoul and extends to nearby provinces, so no destination is out of reach.

2. Seoul Metro: The Backbone of the City

The Seoul Metro is the most popular and efficient way to get around the city. It consists of 23 lines that serve not only Seoul but also its surrounding areas, such as Incheon and Gyeonggi-do. The metro operates from 5:30 AM to midnight, and trains arrive every 2-3 minutes during peak hours and every 5-10 minutes during off-peak times.

Key Features of the Seoul Metro

Color-Coded Lines: Each line on the Seoul Metro is color-coded, making it easy to identify which route to take.

The most commonly used lines include:

• Line 1 (Dark Blue): Connects northern and southern Seoul, passing through major stops like Seoul Station.
• Line 2 (Green): The loop line that encircles central Seoul, passing popular districts like Gangnam, Hongdae, and Dongdaemun.
• Line 4 (Light Blue): Convenient for accessing cultural sites like Gyeongbokgung Palace and Namdaemun Market.
• AREX Line (Orange): Connects Seoul to Incheon International Airport, making it ideal for airport transfers.

English-friendly: All metro stations have English signage and announcements, so even if you don’t speak Korean, navigating the metro system is easy.
Clean and Safe: The stations and trains are impeccably clean, and CCTV cameras are installed throughout the system, ensuring a high level of safety.

How to Use the Seoul Metro

Purchase a T-money card: Before boarding, get a T-money card from any convenience store (GS25, CU, 7-Eleven) or from ticket machines at metro stations.
Top up your card: Recharge the card with a desired amount (most tourists start with around 10,000 KRW). T-money cards can be topped up at convenience stores or at recharging machines located in the metro stations.
Tap to enter: When entering the metro station, tap your T-money card at the gates. Make sure to keep the card handy for when you exit, as you’ll need to tap it again to leave the station.
Transfer stations: Transferring between lines is seamless. Simply follow the transfer signs within the station, and tap your T-money card when exiting your final destination.

3. City Buses: Reaching Every Corner of Seoul

Seoul’s bus system complements the metro network and is especially useful for reaching destinations that aren’t conveniently served by the subway. There are four types of buses, each distinguished by color, which indicate their routes and areas of operation.

Types of Buses in Seoul:

• Blue Buses (Main Lines): These buses travel longer distances and connect different districts of Seoul.
• Green Buses (Local Lines): These are feeder buses that connect to subway stations and travel shorter distances within neighborhoods.
• Yellow Buses (Circular Lines): Circular buses travel within a specific district, connecting major landmarks and subway stations.
• Red Buses (Express Lines): These buses connect Seoul to surrounding satellite cities, such as Suwon, Goyang, and Ilsan. Red buses are ideal for day trips to nearby areas outside Seoul.

How to Use the Bus System

Boarding the bus: All buses have T-money card readers located at the front and rear doors. When boarding, tap your card on the reader at the front of the bus. If you plan to transfer to another bus or the metro, be sure to tap again when exiting.
Reading bus routes: Bus stops are clearly marked with English signage. Each stop lists the bus numbers and the major stops they cover. You can also check real-time bus arrivals using apps like KakaoMap or Naver Maps.
Seating arrangements: Some buses have priority seating for the elderly, disabled, or pregnant passengers. During rush hour, buses can get crowded, so it’s common to stand.

4. Taxis in Seoul: Affordable and Convenient

For tourists who prefer door-to-door service or for trips late at night when the metro is closed, taxis are a convenient option. Taxis in Seoul are relatively inexpensive compared to other major cities around the world. While the base fare starts at 3,800 KRW, the price increases based on distance and time.

Types of Taxis in Seoul

• Standard taxis: These are the most common taxis in Seoul, easily recognizable by their orange or silver color.
• Deluxe taxis: These black taxis offer a more luxurious experience, with more space and comfort. The base fare for deluxe taxis is higher, starting at around 6,500 KRW.
• International taxis: Specially designed for foreign tourists, these taxis are operated by drivers who can speak English, Chinese, or Japanese. International taxis can be booked in advance through apps or at the airport.

Tips for Using Taxis

Flagging a taxi: You can flag down a taxi on the street by raising your hand, or you can use apps like Kakao Taxi to call one.
Communicating with the driver: Most taxi drivers don’t speak fluent English, so it’s helpful to have your destination written in Korean. You can use a translation app or show the driver the name of the place in Korean on your phone.
T-money: Some taxis accept T-money for payment, but it’s always a good idea to have cash or a credit card on hand just in case.

5. T-money Card: Your Essential Travel Pass

As mentioned earlier, the T-money card is a rechargeable smart card that works across all forms of public transportation in Seoul. It’s the most convenient way to pay for fares on the subway, buses, and even some taxis. Additionally, you can use the T-money card to make purchases at convenience stores, vending machines, and even for admission to certain tourist attractions.

Where to Buy and Recharge T-money Cards

Purchase: You can purchase T-money cards at any convenience store (such as GS25 or 7-Eleven) or at metro station kiosks.
Recharge: You can top up the card at convenience stores or at the automatic recharging machines located in every metro station.
Cost and Discounts: A new T-money card costs about 2,500 KRW, and you can add any amount of money to it. Using T-money gives you a small discount on metro and bus fares, and it also makes transferring between buses and subways seamless and free if done within 30 minutes.

6. Navigating Seoul’s Airports: Incheon and Gimpo

Two main airports serve Seoul: Incheon International Airport (ICN) and Gimpo Airport (GMP). Getting from the airport to the city center is simple thanks to the extensive transportation options available.

From Incheon International Airport:

AREX (Airport Railroad Express): The fastest and most convenient option to get from Incheon Airport to Seoul Station. The express train takes about 43 minutes and costs around 9,500 KRW. There’s also an all-stop train option that is cheaper (about 4,750 KRW) but takes longer.
Airport Limousine Buses: These buses connect the airport to various parts of the city and are a good option if you have a lot of luggage. The fare is around 10,000–15,000 KRW, depending on the destination.
Taxis: Taxis are also available, though they are the most expensive option (around 50,000–90,000 KRW, depending on the time of day and destination).

From Gimpo Airport:

Gimpo Airport is closer to the city, and you can take the AREX line, subway Line 5, or taxis to reach Seoul easily. The trip takes around 20-30 minutes by public transport.
