A Noobie Guide to the Seoul Subway: Map, Tips, & Must-Know Info

You’ve probably heard that Seoul has one of the most efficient subway systems around.

But does looking at the maps leave you scratching your head?

Don’t worry, you’re not alone! It’s actually one of the easiest and best public transportation systems in the world.

Understandably, the Seoul subway map might seem a bit overwhelming at first. All those complex train lines and station names.

But trust us - it’s way simpler than it looks.

With our easy guide, you’ll be navigating the Seoul Metro like a pro in no time.

Here's all you need to know:

First, Download the Seoul Subway Map

Before you start your journey, it might help to visualise the map. You'll at least get an idea of where you're going and how long your journey will take.

You can either mark your journey on the actual map or note it down on your app of choice. Or simply download a PDF of the official Seoul metro map in English - the choice is yours.

First things first, though, you can also check out the Seoul Metro Cyber Station website.

It lets you search for Seoul subway stations and routes.

And you can even find information way beyond train stations and routes. Think lockers for luggage storage, currency exchange, and breastfeeding rooms at various stations.

Understanding the Basics of the Seoul Metro

Seoul’s train system has more than 20 lines and almost 300 stations. So, the entire capital is pretty much connected, no matter where you want to go.

Trains run non-stop from 5:30am to midnight. But do keep in mind that the Seoul subway rush hour is from 8am to 9am and 6pm to 7pm on weekdays.

Whether you're staying at a hotel or a friend’s place, you'll have no trouble getting where you need to go and back.

The stations are color-coded with clear logos and English names. And it is super easy to spot your stop on the map. No worries even if the Korean language or reading Hangeul is foreign to you.

When it comes to the best app to easily navigate the Seoul metro, definitely use the Naver app. Google won’t be as helpful here.

The Google Maps app isn’t as reliable as it is in other countries because of mapping data restrictions. Besides Naver, the KakaoMap app is another great alternative.

Pro tip: The Naver app will display specific numbers for each Seoul metro line. These numbers refer to the best carriages to board for the quickest route to your transfer or exit. You’ll also see these numbers marked on the platform, so keep an eye out for them.

Seoul Metro Fares & Ticketing Options

Seoul’s subway gives you two ways to pay: a single-journey ticket or a transportation card.

If you're already at the station, you’ll need physical cash in Korean Won (KRW).

But honestly, the easiest way to get around is with a T-Money or NAMANE card. Both are super handy since you can also use them for taxis and buses, not just the subway.

If you’re only hopping on the train a couple of times, a single-journey ticket will do just fine.

But if you plan on exploring a lot, a transport card is a total game-changer. It’s way more convenient and will save you money in the long run.

Which Transportation Card Should You Go For?

Well, it really depends on the perks you’re willing to pay for.

For instance, the NAMANE card works like a debit card. You can use it for convenience store runs, dining at select restaurants, cafés, and PC cafés. And, of course, for taking the subway, as well.

What’s great is that if your card runs low on funds, you can easily top it up. Just head to a fare adjustment machine near the ticket gate or at any CU, Emart24, or StoryWay. Plus, you can also top up NAMANE with different currencies.

And what's cool is that you can customise the NAMANE card too. Makes it worth getting one for your Korea trip, in any case.

Customised NAMANE cards

T-Money, on the other hand, is a solid choice because it doesn’t expire - you can keep it for all your future trips to Korea. Just keep in mind that your unused balance is valid for up to five years.

Need to recharge your T-Money card? You can do it at any subway station, convenience store, or through the Korea Tour Card app.

One drawback is that the T-Money card doesn't have the debit card feature that the NAMANE card has. Plus, you can't customise it. However, there are collaborations with brands like LINE for some seriously cute cards!

Ultimately, there's a reason why a T-Money card is the most popular choice. You can pre-book one in advance and pick it up at the airport (Incheon International Airport or Gimpo International Airport). Oh, and best of all? You can use it beyond Seoul if you're planning to explore other parts of South Korea.

There's another option too: the WOWPASS, which you can use as both a transportation card and a debit card. Like NAMANE and the T-Money card, you can also use it to pay for taxi fares and subway trips.

Here's a look at all the different card options below:

Pro tip: If you have Samsung Pay, you can toggle on T-Money and use your phone to pay for rides!

Either way, you can’t go wrong. There's no such thing as a bad transportation card for tourists in Seoul. They’re all flexible and multi-use; it just depends on what you’re using it for.

Discover Seoul Pass: Attractions + Transportation

Want to kill two birds with one stone? Why not get a transportation card that doubles as an attraction pass - like the Discover Seoul Pass!

It gives you access to tons of attractions in Seoul and works just like a T-Money card for public transport.

Just top it up, tap, and go.

Here’s the full list of attractions you can check out with the Discover Seoul Pass in case you're lacking ideas for things to do in the capital.

How to Buy Single Use Tickets

If you know you'll only be using the Seoul subway occasionally, this might be the best option for you.

No need to worry about insufficient funds on your card. Buying a single-journey ticket is super simple.

At any subway station, just head to a ticket vending machine. The screen will guide you with easy-to-follow prompts, like where you're going, ticketing options, and a language menu, etc.

Besides the ticket fare, you'll need to pay a deposit of KRW 500 for the card itself. However, you'll get it back once you return the card at your destination.

1. Scan your single-journey ticket card at the T-Money scanner to enter the turnstile.

2. When you reach your destination, scan it again at the exit turnstile.

3. To get your KRW 500 deposit back, simply return the card at the “Deposit Refund Device.”

4. If your ticket runs out of funds, no worries! You can easily top it up at a fare adjustment machine near the turnstiles.

Seoul Metro Etiquette

Seoul's subways are awesome. But it's good to keep things smooth for everyone. Koreans are generally pretty civic-minded, so you can do your part to make the ride more comfortable

Here are a few quick tips to be a respectful rider:

• Line up and wait your turn: Stand behind the markers on the platform so you don’t block people getting off. Let everyone exit before you hop on.

• Give up your seat for those who need it more: Keep an eye out for senior citizens, people with disabilities, pregnant women, and young children. If someone needs a seat, kindly offer yours. You can even say “anjeuseyo,” which means "please sit," when offering your seat. And remember - don’t sit in the priority seats unless you really need to.

• Mind your manners on escalators: If you’re not in a hurry, stand on the right side of the escalator so people can pass you if they need to.

• Keep it quiet and clean: Try to avoid talking loudly or blasting music/TikToks on your phone. Eating on the train is allowed. But it’s probably best to skip it out of respect for others.

• Don’t take up unnecessary space: If you’ve got bags, don’t put them on the seats. There are railings above to stow them.

• Getting off the train: Seoul Metro can get crazy crowded! If it’s rush hour, you can say “naerilgeyo” (which means “I’m getting off”) or “jamsimanyo” (which means “excuse me”) to make your way through.

Seoul Metro Operating Hours

Seoul's metro runs like clockwork, with the first train at 5:30am and the last one around midnight or 1am the next day.

Just a heads up: some lines might close a little earlier.

Be sure to listen for station announcements to avoid missing your train.

Don’t rely too much on subway apps for real-time closure info, as they might not always be up-to-date. It’s a good idea to give yourself a little extra time, to be safe.

Seoul Subway System Facilities

Seoul's public transportation system is more than convenience. Here are some amenities to look out for below:

• Convenience Stores: Most stations have convenience stores and restaurants. Perfect for grabbing a snack or a quick meal, topping up your card, or buying tissues, face masks, and phone cases.

• Lockers: Many stations have lockers where you can leave your bags for up to four hours. That's if you don’t want to carry them around all day. You won’t need to worry about coins either, as the lockers are payable with your T-Money card. For long-term luggage storage in Seoul, it might be better to contact businesses like Luggez and Bounce.

• Breastfeeding rooms: New moms can find peace of mind with designated breastfeeding rooms. Use the Naver Maps app to search for them by tapping on the station name. It's easy. Just look out for the bottle icon next to “수유실.” If the icon is greyed out, that means the nursing rooms are unavailable.

• Wheelchair access: Many stations have wheelchair lifts for added convenience. You can check the Naver app to see if they are available. To find breastfeeding rooms, look for “휠체어 리프트” next to the wheelchair icon and see if it’s greyed out. For toilets, keep an eye out for the wheelchair icon with “장애인화장실” next to it.
