South Korea’s railway network makes it easy to explore lively cities, coastal scenery, and historic destinations. High-speed trains connect major regions quickly, while local rail services offer more stops along the way.

With advance booking and a little planning, train travel can be a comfortable way to discover the country.

Choose the Right Train

KTX trains provide high-speed connections between major cities, while ITX services are generally slower and stop at more stations. KTX offers Standard and First Class seating. Standard Class is comfortable for most travelers, with onboard Wi-Fi and charging points available on many services.

Book Tickets Early

Popular trains can fill up on weekends and holidays, so booking ahead helps secure your preferred departure. Tickets are available online and at railway stations, where major terminals usually have English signage. As a rough guide, one-way KTX fares may cost around US$40–US$55 from Seoul to Busan and US$25–US$35 from Seoul to Gangneung. Prices depend on the service, seat class, and exchange rate, so check current fares before booking.

Follow Train Etiquette

Keep conversations quiet, silence your phone, and avoid disturbing other passengers. Snacks and drinks are generally acceptable, but keep your seat area clean and avoid foods with strong smells. Store luggage neatly and leave priority seats available for passengers who need them.

Get Around Cities

Local navigation apps such as Naver Map can help with train schedules and public transport connections. In Seoul and Busan, metro systems make it easy to continue your journey after arriving by train. A rechargeable T-money card is useful for many bus and subway journeys. The card typically costs around US$2–US$4 before travel credit, although prices vary. Check local payment options and fares before traveling.

Check Journey Times

Approximate journey times include:

Seoul to Busan: 2 hours 45 minutes

Seoul to Gangneung: 1 hour 49 minutes

Gangneung to Gyeongju: 2 hours 50 minutes

Gyeongju to Busan: 35 minutes

Times vary by service and timetable, so confirm your departure before arranging activities.

Traveling by train is a practical way to experience South Korea’s cities, coastlines, and regional attractions. Choose the service that suits your itinerary, reserve seats early for busy routes, and budget for tickets and local transit. With a reliable navigation app and a little preparation, exploring South Korea by rail can be simple and enjoyable.
