💳 Choosing Your Transit Pass: T-money vs. Climate Card

Foreign visitors primarily choose between a standard reloadable card and an unlimited regional pass:

• T-money / Nationwide Compatible Cards:

  • Best For: Travelers exploring multiple cities (Seoul, Busan, Jeju, Gyeongju).

  • Price: ~₩3,000 to ₩5,000 for the physical card (available at all convenience stores and subway kiosks).

  • Top-Up: Cash only (KRW) at station kiosks or convenience store counters.

  • Flexibility: Pay-per-ride across all subway lines, local buses, intercity transit, and taxis nationwide.

• Climate Card (Seoul Tourist Pass):

• Best For: Travelers staying intensely within Seoul for 1 to 7 days taking 3+ rides per day.

• Pricing: ₩5,000 (1-Day), ₩8,000 (2-Day), ₩10,000 (3-Day), ₩15,000 (5-Day), ₩20,000 (7-Day), plus ₩3,000 for the physical card.

• Coverage: Unlimited rides on Seoul subway lines and Seoul city buses.

• Limitation: Does not cover travel outside Seoul (such as AREX express to Incheon Airport or lines extending deep into Gyeonggi-do).

🔄 Essential Transit Rules & Transfer Discounts

South Korea uses a distance-based integrated transit discount system:

• The Transfer Window: You can transfer between subways and buses (or bus-to-bus) for free or at a discounted distance rate up to 4 times within 30 minutes (extended to 60 minutes from 9 PM to 7 AM).

• Always Tap Out: Always tap your transit card on the sensor when exiting buses and subway gates. If you fail to tap out on a bus, you forfeit the transfer discount and pay the maximum distance surcharge on your next ride.

• No Open Drinks on Buses: City buses strictly prohibit open cups of coffee, bubble tea, or unsealed food. Seal containers in a bag or finish them before boarding.

🦉 Getting Around After Midnight: The Owl Bus

Seoul subways generally stop operating around midnight, but you never need to rely solely on late-night taxis.

• Identification: Late-night buses are designated with an "N" prefix (e.g., N15, N26, N62).

• Operating Hours: 11:30 PM to 4:00 AM.

• Key Routes for Travelers:

  • N26: Connects Hongdae, Sinchon, Jongno, Dongdaemun (DDP), and Cheongnyangni.

  • N62: Connects Hongdae, Sinchon, Euljiro, Dongdaemun, and Konkuk University.

  • N13 & N37: Link Gangnam and southern nightlife hubs to Central Seoul (Seoul Station / Jongno).

• Fare: Flat card fare of ₩2,500 (T-money and Climate Card both accepted).

📱 Transit Navigation Pro-Tips

• Ditch Google Maps for Walking & Live Transit: Google Maps does not support full pedestrian turn-by-turn navigation in South Korea due to local mapping regulations. Download Naver Map or KakaoMap and switch the display language to English for live bus arrival countdowns and platform transfer door numbers.

• Subway Gate Direction: Always check the overhead directional sign before tapping into the turnstile. If you accidentally tap into the wrong platform direction on standard T-money, tapping out and re-entering the opposite gate within 15 minutes is free at most stations.
