Types of Taxis:
- Regular Taxi – orange or silver; standard fare.
- Deluxe Taxi – black with a yellow sign; higher fare, better service.
- Jumbo Taxi – larger vehicles for groups or luggage.
- International Taxi – English-speaking drivers, available in Seoul.
💡 Tip: Use apps like Kakao T or UT (Uber Korea) to book a taxi and avoid language issues.
4. How to Pay: T-money Card
The T-money card is a rechargeable transportation card used on subways, buses, and even in taxis and convenience stores. It’s a must-have for anyone staying in Korea for more than a few days.

- Can also be purchased and reloaded at subway stations.
Benefits:
- Transfer discounts between buses and subways.

5. High-Speed Rail: KTX and More
If you're planning to travel across the country, KTX (Korea Train Express) is the fastest way. Operated by Korail, these bullet trains connect major cities like Seoul, Busan, Daejeon, and Gwangju in just a few hours.
Other train options:
