Even as a Local, Seoul’s Subway Can Be Confusing – Here’s How to Make It Easier : Seoul subway guide
1. Introduction: Mastering the Seoul Subway Like a Local
Seoul’s subway system is one of the most efficient, affordable, and well-connected public transportation networks in the world. With 23 lines covering over 1,000 km, it’s a traveler’s dream—but also a bit overwhelming, even for locals. As someone who has lived in Korea my whole life, I still find certain stations and transfer points confusing. If I sometimes struggle, I can only imagine how first-time visitors feel. So here is Seoul subway guide for you!
To make things easier, I’ll share essential tips, tricks, and must-know hacks for navigating Seoul’s subway safely and efficiently. One of the most important tools you can use? Naver Map. If you’re used to Google Maps, you’ll quickly find that it’s not as helpful in Korea. Let’s dive in.

2. Why Naver Map is a Must-Have for Subway Navigation
If you’ve traveled to other countries, you might rely on Google Maps. However, in Korea, Google Maps is not as accurate or reliable as Naver Map, especially for public transportation. Here’s why you should download Naver Map before using the Seoul subway:
- More accurate real-time subway schedules (Google Maps lacks live updates for Korea)
- Turn-by-turn navigation inside stations (helps when transferring between lines)
- Multi-language support (English, Japanese, Chinese available)
- Exit number guidance (Find the exact subway exit for your destination—critical for finding landmarks and attractions)
- Fares and journey times displayed clearly
Naver Map also shows real-time train congestion levels, which can help you avoid packed subway cars. You can download Naver Map on both iOS and Android.
For more details on Naver Map’s functionality, check out the Naver Map Official Website.
3. How to Buy and Use a Subway Card in Seoul
Before hopping on the subway, you’ll need a transportation card. Here are your best options:
| Card Type | Where to Buy | Best For |
|---|---|---|
| T-money Card | Convenience stores (CU, GS25, 7-Eleven), subway stations | Most travelers |
| Cashbee Card | Convenience stores, some subway stations | Alternative to T-money |
| Korea Tour Card | Airports, major subway stations, online | Travelers looking for extra discounts |
| M-Pass | Incheon Airport only | Unlimited rides for 1, 2, 3, 5, or 7 days |
For a more detailed guide on choosing the right transportation card, check out my post here: Complete Guide to Korea’s Transportation Cards.
To use the card, simply tap it on the reader at the turnstile when entering and exiting the subway. You can also use T-money on buses and taxis, making it a great all-in-one travel card.

4. Understanding Seoul’s Subway Lines & Transfers
Seoul’s subway has color-coded lines, making navigation easier. However, with so many lines intersecting, transfers can be tricky. Here’s how to transfer smoothly:
- Follow the colored arrows on the floor—they guide you to the right line.
- Look for shortcuts inside stations. Some stations have express transfer paths that save time.
- Use Naver Map to check which subway car to board for the fastest transfer route.
Major transfer stations can be particularly confusing, even for locals. If you’re ever unsure, don’t hesitate to check Naver Map for step-by-step directions.
5. Staying Safe & Navigating Rush Hours
Seoul’s subway is safe, but it gets extremely busy, especially during rush hours (7:30-9:00 AM & 6:00-8:00 PM). Here’s how to stay comfortable and respectful:
- Hold your bag close in crowded trains.
- Stand on the right, walk on the left on escalators.
- Priority seats are for the elderly, pregnant women, and disabled passengers.
- If carrying luggage, use subway station elevators instead of escalators. Naver Map shows elevator locations inside stations.
Even as a local, I try to avoid rush hours whenever possible. The trains can get so packed that it’s hard to move, so plan accordingly if you prefer a more comfortable ride.
6. Special Features & Hidden Gems in the Seoul Subway
