2. How to Ride the Subway: Step-by-Step

Follow these steps to navigate the stations with ease:

1. Search Your Route: Use Google Maps, Naver Map (local favorite), or the VISITKOREA(Click) website to find your destination.
2. Find the Entrance: Look for the subway entrance sign and head downstairs.
3. Check the Direction: Platforms are divided by direction. Look at the signs for the Final Destination (e.g., “Toward Incheon” or “Toward Gimpo Airport”) to ensure you are on the correct side.
4. Tap and Board: Tap your card on the gate reader and enter.
5. Master the Transfer: Switching lines? Do not go outside the gate. Follow the arrows and colored lines on the floor or ceiling that match your next line.
   • Example: At Wangsimni Station, to switch from Line 2 to Line 5 (toward Gwanghwamun), simply follow the Purple arrows inside the station.
6. Find the Exit: Exits are numbered (1, 2, 3…). Check the station maps or signs to find the number closest to your destination.

💡 Pro-Tips for a Smooth Ride (Don’t Miss This!)

• Cash is Essential: Except for Contactless Payment, you must have Korean Won (KRW) cash to buy or top up cards at subway stations.
• Keep Your Passport: You need a physical passport to issue a WOWPASS or use a KORAIL PASS.
• The “Transfer” Benefit: Tagging your card when exiting allows for free transfers between buses and subways—don’t forget!
• The Red Emergency Handle: Never pull the red handle next to the doors unless it’s a real emergency. The doors open automatically at every station!
• Respect Reserved Seats: Keep the seats at the ends of each car (for the elderly) and the pink seats (for pregnant women) empty, even if the train is crowded.
• Lost Something?: If you lose an item, don’t panic. Seoul Metro has a very efficient “Lost and Found” system. Note your train number and time for a faster search. (Click)
