How to Use Korean Subway Like a Local (Complete Beginner Guide)
Google Maps does not work properly in Korea. Here is how locals actually navigate the subway — including the one app every tourist needs.
Traveling around Korea is surprisingly easy once you understand the subway system. Seoul's subway is clean, fast, affordable, and one of the best public transportation systems in the world.
But many foreign travelers run into the same problem:
"Google Maps doesn't work properly in Korea."
That's why locals always use Korean navigation apps instead. This guide walks you through everything — from downloading the right app to riding like a local on day one.
Why You Should NOT Rely on Google Maps in Korea
Unlike most countries, Google Maps in Korea has severely limited navigation features. Turn-by-turn directions, real-time transit data, and route accuracy are all restricted due to Korean mapping laws.
For subway travel, local Korean apps are far more accurate and reliable. Most locals use:
- KakaoMetro — subway-only, simple interface
- Naver Map — full navigation (subway + walking + driving)
- KakaoMap — similar to Google Maps but works in Korea
For first-time visitors, KakaoMetro is the best starting point. It's focused entirely on subway navigation and easy to use even without reading Korean.
Step 1: Download KakaoMetro
iPhone (iOS)
Android
The app is free and requires no sign-up to search routes.
Step 2: Change the Language to English
When you first open KakaoMetro, everything appears in Korean. Here's how to switch it to English in under a minute:
- Open KakaoMetro
- Tap the menu icon in the top-left corner (☰)
- Go to Settings
- Find Language
- Select English
After switching, station names, line labels, and navigation instructions all appear in English. The interface becomes much easier to follow.
Step 3: Search Your Route
Using the app is straightforward once the language is set.
Example: Getting from Hongdae to Gangnam
- Tap the search bar at the top
- Enter your departure station (e.g. Hongdae)
- Enter your destination (e.g. Gangnam)
- The app instantly shows:
- The fastest route
- Which lines to take and where to transfer
- Total travel time
- Subway line colors
- Last train time ← especially important at night
⚠️ Korean subways stop running around midnight. Always check the last train time before heading out late.
Understanding Korean Subway Lines
Each subway line has its own color and number. Inside stations, every sign is color-coded — so even if you can't read Korean, following the line color is usually enough to get where you're going.
| Line | Color | Key Stations |
|---|---|---|
| Line 1 | Dark Blue | Seoul Station, Dongdaemun |
| Line 2 | Green | Hongdae, Gangnam, Sinchon |
| Line 3 | Orange | Gyeongbokgung, Apgujeong |
| Line 4 | Light Blue | Myeongdong, Seoul Station |
| Line 9 | Gold | Gimpo Airport → Gangnam (express) |
Bonus Tips for Riding Like a Local
T-Money Card — Your One Card for Everything
Before you ride, you'll need a T-Money card — the rechargeable transit card used on all subways, buses, and taxis across Korea. We've put together a full guide on how to get one, where to top it up, and how to use it:

Stand on the Right, Walk on the Left
On escalators, locals stand on the right side and leave the left side open for people in a hurry. Follow this rule and you'll blend right in.
Quiet Carriages
The first and last cars on most Seoul subway lines are designated quiet carriages. Phone calls and loud conversations are discouraged. Look for the signs when boarding.
Seats for the Elderly and Pregnant
The pink seats at each end of the carriage are reserved seats. Even if the train is empty, most locals avoid sitting in them. Do the same.
Final Thoughts
The Korean subway system is genuinely one of the easiest in the world to navigate once you have the right app. Download KakaoMetro before your trip, switch it to English, and you'll be moving around Seoul like a local within your first hour.
