Introduction: Why KTX is great for travel in Korea
Have you ever wished you could zip across Korea in just a couple of hours? When I first took the KTX, I was amazed at how comfortable, fast, and punctual it was. The KTX (Korea Train Express) connects major cities, slicing what would be long bus or car journeys into relaxing train rides.
It matters because for foreign travelers, choosing between buses, flights, and trains can be confusing. You’ll learn in this guide how to ride the KTX like a local — from buying tickets, boarding, to knowing which routes are must‑tries. By the end, you’ll feel confident hopping on a train in Korea.
How to Use KTX: Tickets, Boarding & Etiquette
Ticketing: Online, at station, or via pass
You can book KTX tickets online via Korail’s website or international sites. It’s especially smart to reserve ahead during weekends or holidays because popular routes fill fast. At the station, there are self‑service machines and ticket counters. Be aware: sometimes foreign credit cards may not work at kiosks, so you might have to go to a ticket counter. Also, foreign visitors can use the KR Pass (Korea Rail Pass), which offers unlimited KTX (and other Korail) rides over a set number of days.
Boarding & seat etiquette
Arrive at the station at least 20–30 minutes before departure. Many people board early — some even 45 minutes ahead. On KTX, once the platform opens, you can walk straight onto the train and find your assigned seat. Match your car number and seat number printed on your ticket. Keep aisle clear, store luggage in racks, and avoid blocking others.
Onboard services & comfort
The KTX is relatively comfortable: power outlets at seats, restrooms, sometimes Wi-Fi (though reliability varies). For longer rides, there is usually a food cart or trolley service offering snacks and drinks. Keep your ticket ready — staff may check it during the ride.
Arrival & departure tips
Trains tend to run very punctually, so don’t be late. As you arrive, gather your things and exit in an orderly manner. If your credit card didn’t work online or at kiosks earlier, many stations have staffed ticket counters that can help in English.
Book in advance for busy routes (especially Seoul ↔ Busan) and avoid relying on kiosks only — have a fallback of counter purchase just in case.
Insider Tips to Make Your Ride Smoother
Choose less busy times
If possible, avoid peak travel times (Friday evenings, holiday periods like Chuseok, Lunar New Year). Trains fill up fast. Booking early helps a lot.
Use KR Pass smartly
If you plan to travel across multiple cities in a short period, the KR Pass often gives better value than buying separate tickets. Just check whether your intended routes are covered.
Start or end your trip with “in between” cities
Rather than going straight Seoul → Busan in one shot, consider stopping in cities like Daejeon or Daegu to break the journey and explore local charms. Locals often use intercity KTX segments.
Ride scenic lines or branch lines
Try lines less famous to see different views. For example, the Gangneung Line (Seoul → Gangneung) gives you quick access to the east coast. Also, branch lines: from the Honam line you can switch toward Jeonju, Yeosu, etc.
Keep an eye on when to board
Some travelers mention that even if the train seems empty early, staff won’t check tickets until the train is moving. So walking on early is okay, but you still need to be in the correct seat.
The Best KTX Routes Locals Love
Seoul ↔ Busan (Gyeongbu Line)
This is the most classic and busiest KTX line. Travel time ~2h30min on express services. Stops include Daejeon, Daegu, Ulsan. It connects Korea’s two largest cities and is a “must‑experience” route.
Seoul ↔ Gwangju / Mokpo (Honam Line / Honam HSR)
The Honam high‑speed line branches off the main line toward southwestern Korea. You can reach Gwangju in about 1.5 hours and Mokpo in ~2.5 hours. It’s great if you want to explore the Jeolla region’s culture and cuisine.
Seoul → Jeonju / Yeosu (Jeolla Line branch)
Jeonju, famous for its hanok village and food scene, is reachable via KTX (around 1 hour 50 minutes). Yeosu, which is a coastal gem, is also accessible via this branch — nice if your trip includes the south coast.
Seoul → Gangneung (Gangneung Line)
This is the east coast KTX route. It’s newer and gives access to the scenic east sea areas. Locals use this especially in summer or for seaside getaways.
Intermediate stop suggestions
If you don’t want to travel nonstop, towns like Daejeon, Daegu, or even Iksan, are great stopovers to experience a different side of Korea off the beaten path.
Frequently Asked Questions
Q1: Can I change seat or train after I have a ticket?
It depends on fare type. Some flexible tickets allow changes; strictly discounted ones may not. Visit a ticket counter to ask if changes are possible.
Q2: What if I lose my ticket?
Go to the station staff as soon as possible. They’ll help you issue a duplicate after verifying your details.
Q3: Is English available in stations or on KTX?
Major stations have English signs. Staff at bigger stations often know basic English or use translation tools. Onboard announcements sometimes include English.
Q4: How much luggage can I bring?
There’s no strict luggage limit like airlines, but you should keep your items within manageable size. Use overhead racks or space at car ends. Avoid blocking aisles.
Q5: Can I board a different KTX in a different city?
Yes — you don’t always have to board at the origin station if your ticket includes that segment, and stations have facilities to issue or change tickets elsewhere.
Conclusion: Enjoy Korea by High‑Speed Rail
Riding the KTX is one of the most efficient and enjoyable ways to connect between Korea’s major cities. With some planning — booking ahead, knowing which routes to try, and following local boarding norms — you’ll feel like a savvy traveler.
Don’t be afraid to explore off the main path. Whether it’s Jeonju’s hanok streets, Gangneung’s ocean breeze, or Gwangju’s food culture — each route has its own reward.
Plan ahead for popular routes, be flexible with stops, and ride comfortably — KTX lets you see more of Korea in less time.
