South Korea 14-Day Route with Public Transport & KTX Trains
By Travel Architect • March 20, 2026
South Korea possesses one of the world’s most punctual, clean, and efficient public transport networks. Traveling from Seoul to Gyeongju and Busan using high-speed KTX trains is smooth, affordable, and stress-free when you know the rules.
3 Essential Rules for Korean Public Transit
- Never Rely on Google Maps: Google Maps cannot provide walking or subway directions in South Korea. Install Naver Map or KakaoMap before arrival.
- Buy a T-Money Card at the Airport: Load cash (Korean Won) onto your T-Money card at any convenience store (CU, GS25, Seven-Eleven). It works seamlessly across subways and city buses nationwide.
- Book KTX Tickets 30 Days in Advance: KTX trains between Seoul and Busan fill up quickly, especially on weekends. Book directly on Korail’s official site.
