Seoul subway basics

Core habits

1. 1
   Use Naver Map or KakaoMap for door-to-door routes (often clearer than Google for transfers).
2. 2
   Tap T-money (or compatible card) at the gate; keep it handy for exit.
3. 3
   Follow line colors + destination names on platform screens.
4. 4
   Stand on the side for boarding queues; let people exit first.

Transfers

• Large stations (e.g. Seoul Station, Gangnam, Express Bus Terminal) can mean long walks — budget time.
• Transfer discounts usually require tapping correctly within a time window; if a fare looks wrong, ask station staff.

Accessibility & luggage

• Elevators exist but are not always next to every exit — check exit numbers in the map app.
• Rush hours (weekday mornings/evenings) are crowded; keep bags close.

Etiquette (appreciated norms)

• Quiet phone calls; priority seats for those who need them.
• Eat discreetly; avoid messy food on trains.
• Don’t block doors with suitcases during boarding.

Fares

Distance-based. Prefer live estimates in official/metro apps or map apps over any printed number in a blog.

Night & last trains

Last-train times vary by line and day. If you’re out late, check the app before entering the paid area — or budget a taxi.
