Quick Answer: South Korea has world-class public transport. Get a T-money card at the airport immediately, use the AREX airport express to reach Seoul in 38 minutes, and take the KTX bullet train for intercity travel. Download Kakao T for taxis and Naver Map for navigation.
Transport Overview
South Korea's public transportation system is one of the most advanced and efficient in the world. Whether you're exploring Seoul's sprawling metropolis or traveling between cities, you'll find clean, punctual, and affordable options.
- Metro/Subway: Extensive networks in Seoul, Busan, Daegu, Gwangju, Daejeon, and Incheon.
- KTX (Bullet Trains): High-speed rail connecting Seoul to major cities at up to 305 km/h.

⚠️ Google Maps Limitation: Google Maps has limited functionality in South Korea due to national security mapping restrictions. Use Naver Map or Kakao Map instead — both are far more accurate for Korea with real-time transit directions.
T-money Card: Your Essential Travel Companion
The T-money card is a rechargeable smart card that is absolutely essential for getting around South Korea. Think of it as your all-in-one transit pass and small-payment card.
What Is T-money?
T-money is Korea's universal transit card. It works on virtually every form of public transport in the country and can also be used for small purchases at convenience stores, vending machines, and some taxis.

| Works On | Seoul metro, all city buses, KTX (tap at gates), some taxis, convenience stores |
| Where to Buy | Any convenience store (CU, GS25, 7-Eleven), metro station vending machines, airport |
| How to Top Up | Convenience store counter, metro station machines (cash or card), some bank ATMs |

T-money Pro Tips
- Load ₩20,000–50,000 to start. You can always top up more later.

Taxis & Kakao T
Taxis in South Korea are affordable, safe, and metered. They're an excellent option for late-night travel, short distances with luggage, or reaching destinations not near metro stations.
Taxi Types
| Type | Color | Starting Fare | Notes |
|---|---|---|---|
| Standard | Orange/White | ₩4,800 | Most common, metered |

| Jumbo | Various | ₩7,000 | Seats 5-8 passengers |
| Late Night | Any | +20% surcharge | Midnight to 4 AM |
Kakao T App (Essential)
Kakao T is Korea's taxi-hailing app — think of it as the Korean Uber. It's the easiest way to book a taxi, especially late at night or in busy areas.
- How it works: Enter your destination, see the estimated fare, and a taxi picks you up. Payment is automatic via registered card.
- English interface: The app is available in English.
- Features: Real-time tracking, fare estimates, payment by card (no cash needed), driver rating.
- Availability: Works throughout Seoul and most major cities.
- Tip: In busy areas or during rain, wait times can be longer. Be patient or walk to a less congested pickup point.
⚠️ Avoid Unlicensed Taxis: Always use licensed taxis with a visible meter and taxi sign on the roof. If approached by someone offering a ride without a meter, decline and use Kakao T instead.
Car Rental
Driving in South Korea is possible but not recommended for most tourists, especially in Seoul. Traffic is heavy, roads are complex, and parking is expensive. However, a rental car is useful for exploring rural areas.
Requirements
- International Driving Permit (IDP): Required along with your home country license. Obtain IDP before your trip.
- Age requirement: Most rental companies require drivers to be at least 21 years old.
- Credit card: Required for the security deposit.
When to Rent a Car
- Good for: Exploring Jeollanam-do (southern coast), Gangwon Province (mountains), Jeju Island, and rural areas with limited bus service.
- Not recommended for: Seoul, Busan, or any major city. Public transport is faster and cheaper.
- Rental companies: Lotte Rent-a-Car, AJ Rent-a-Car, and Hertz Korea are reliable options with English websites.
Driving Tips
- Drive on the right side of the road (same as the US and Europe).
- Speed limits: 60 km/h in cities, 80-100 km/h on highways. Speed cameras are everywhere.
- Navigation: Rent a GPS unit or use Naver Map on your phone (it works perfectly for driving directions).
- Tolls: Highways have tolls. Pay with cash or a Hi-Pass card (provided by rental companies).
💡 Jeju Tip: Renting a car on Jeju Island is highly recommended. Public transport on Jeju is limited and infrequent, and the island's attractions are spread out. A rental car gives you complete freedom to explore.
