Public Transportation in Korea

South Korea has one of the most convenient and extensive public transportation systems in the world.

Most places in Korea, including many destinations outside major cities, can be reached by public transportation. Fares are also relatively inexpensive compared with many other countries.

Major cities such as Seoul, Busan, Daegu, Daejeon, and Gwangju have well-developed subway systems. City buses provide extensive coverage beyond the subway network, and many major roads have dedicated bus lanes that allow buses to avoid much of the traffic.

For most travelers, there is little need to rent a car when visiting Korea’s major cities.

Transportation Cards

Public transportation in Korea is largely cashless. Instead of paying cash for every trip, passengers normally use a transportation card or a supported mobile payment service.

The most widely used transportation card is T-money.

Another convenient option for international visitors is WOWPASS, which can be used not only as a transportation card but also for everyday purchases at participating businesses.

Why use a transportation card?

Using a transportation card makes traveling much easier and can also save you money.

Korea’s public transportation system provides transfer discounts when you transfer between eligible buses and subway services within the applicable time period. Instead of paying a completely new fare for every vehicle, the system calculates the appropriate fare based on your journey.

For visitors staying in Korea for several days, using a transportation card is strongly recommended.

Remember to Tap Your Card

You will find card readers at the entrances and exits of buses and subway stations.

Tap your card when you get on — and tap it again when you get off.

This is particularly important because the system uses the tap-out information to calculate fares and transfer discounts.

Forgetting to tap when you get off may result in an incorrect fare or the loss of a transfer benefit.

Easy rule to remember:
Tap IN → Travel → Tap OUT

Use a Local Map App

Korea has excellent local map services, including NAVER Map and KakaoMap.

These apps can tell you:

Which bus or subway line to take
Where to board
Where to get off
Where to transfer
How long the journey will take
When the next bus or subway is expected
Walking directions between stations and destinations

They are particularly useful because Korean public transportation involves many different bus routes and subway lines.

Tip: Keep the Korean name and address of your hotel saved on your phone. It can be very useful when asking for directions or taking a taxi.

A separate guide on how to use NAVER Map and other local map services is available on this website.

Real-Time Arrival Information

Most bus stops and subway stations have electronic information displays showing upcoming services and estimated arrival times.

At bus stops, you can usually see:

Bus route numbers
The destination or direction
The estimated arrival time
How many stops away the bus is

Subway stations also provide information about the next trains and their destinations.

This makes it relatively easy to know when your bus or train is coming without having to guess from a timetable.

Using the Bus

When taking a city bus, passengers normally board through the front door and exit through the rear or designated exit door.

Have your transportation card ready before boarding. When you get on, tap your card on the reader near the entrance.

When getting off, remember to tap your card again.

Buses can become very crowded during rush hour. If you are carrying a large backpack or suitcase, try to keep it out of the way of other passengers.

Using the Subway

Korean subway stations can be very busy, particularly during morning and evening rush hours.

When waiting for a train, stand to the side of the train doors and leave enough space for passengers to get off.

Let passengers exit before you board.

You will often see people naturally form two lines on either side of the subway doors. Once passengers have gotten off, the waiting passengers board.

You do not need to stand in a perfectly straight line. Simply respect the order of the queue and avoid pushing ahead of other passengers.

During rush hour

Seoul’s subway can become extremely crowded during commuting hours.

If possible, avoid traveling during approximately 7:30–9:30 AM and 5:30–7:30 PM on weekdays, especially if you are carrying luggage.

Walking in Seoul

Seoul is a very densely populated city, and sidewalks can become crowded.

People generally keep to the right side when walking, although this is not an absolute rule and pedestrian traffic can be quite flexible.

When walking in busy areas, try to keep to one side rather than stopping suddenly in the middle of the sidewalk.

Be especially careful around:

Subway station entrances
Busy shopping areas
Narrow streets
Bicycle lanes
Delivery motorcycles and scooters

Escalator Etiquette

On escalators, people generally stand on the right side and leave the left side open for people who want to walk.

You will see this especially often in subway stations.

Stand on the right. Keep the left side clear.

However, practices can vary depending on the location and crowd, so simply follow what people around you are doing.

Traveling with Luggage

If you are traveling with a large suitcase, public transportation is still possible, but it can be challenging during rush hour.

Subway stations can be surprisingly large, and some stations have long corridors or multiple levels.

When traveling with luggage:

Avoid rush hour when possible.
Use elevators when available.
Keep your luggage close to you.
Do not block subway or bus doors.
On crowded buses, consider waiting for the next one if there is not enough room.

For airport transfers or several pieces of heavy luggage, a taxi or airport transportation service may be more convenient.

A Little Courtesy Goes a Long Way

Korean public transportation can feel different from what you are accustomed to.

People may not always form perfectly straight queues, but there is generally an understood order of who arrived first.

You will often see passengers quietly waiting near the boarding area and naturally moving forward as others board.

A few simple habits will help you fit right in:

Let people get off before getting on.
Do not push or cut in line.
Keep your voice down on buses and trains.
Avoid blocking doors or passageways.
Give priority seats to people who need them.
Keep backpacks and luggage from taking up extra seats.
Move toward the inside of the vehicle when possible.

Priority & Courtesy Seats

On Korean buses and subways, certain seats are designated for people who may need them, including older passengers, pregnant women, and people with disabilities.

These seats are often marked with different colors or signs.

Even when they are empty, it is generally considered polite to leave them available for those who need them.

Public Transportation at Night

Public transportation is generally safe and convenient, but subway and bus services do not operate 24 hours a day.

The exact last train or bus varies by route and day of the week.

If you are traveling late at night, check the last available service using a local map app before leaving.

If public transportation is no longer available, taxis are widely available in major cities.

1. Get a transportation card.
T-money is the most common choice for visitors.
