How to Use Korea’s Subway Like a Local (2025 Guide)

The Korean subway system is one of the most efficient and affordable in the world, connecting nearly every corner of major cities like Seoul, Busan, and Daegu. For first-time visitors, it might look confusing, but once you understand the basics, you’ll travel like a true local. Here’s a 2025 guide on how to use Korea’s subway – including cards, apps, and insider tips.

1. Get a T-money card (and load it up)

A T-money card is essential for using the subway in Korea. This rechargeable smart card works not only for subways, but also for buses and taxis. You can buy it for about 3,000 KRW at convenience stores (GS25, CU, 7-Eleven) or subway stations. Load it with cash or credit card – a single ride in Seoul starts around 1,400 KRW, making it cheaper than most global cities.

2. Download a subway navigation app

Google Maps isn’t reliable in Korea for public transport directions. Instead, use Subway Korea, KakaoMap, or Naver Map. These apps show train schedules, transfer stations, and even which subway car is closest to the exit you need. They are available in English and will save you from getting lost in massive stations like Seoul Station or Gangnam.

3. Learn how transfers work

One of the best things about the Korean subway system is free transfers between subway lines – and even between subway and bus. When you tap your T-money card, the system automatically calculates transfers, so you won’t be double-charged. Just remember to tap in and out at each station to avoid paying extra.

4. Avoid rush hour if you can

Subways in Seoul are efficient but can be extremely crowded during rush hours (7–9 AM and 6–8 PM). If you can, travel outside of these hours for a more comfortable ride. If you must ride during rush hour, stand on the sides of the doors and be ready for a packed experience.

5. Know the etiquette on the subway

There are unwritten rules for subway etiquette in Korea. Do not sit in the priority seats (marked in yellow) unless you are elderly, pregnant, or disabled. Keep your voice down when talking, and avoid eating or drinking on trains. If you want to fit in like a local, stand on the right side of the escalator and let people pass on the left.
