Watching Busan’s coastal high-rises slowly give way to open countryside from my KTX window, I couldn’t help but reflect on how far I’ve come as a solo traveler. South Korea’s transit system can feel overwhelming at first, but taking the Busan to Seoul by KTX turned out to be one of the smoothest, most peaceful parts of my entire trip.

- Where to book: The official Korail website or app, Klook, or in person at Busan Station
- Booking tip: Reserve a few days ahead for popular slots like early morning departures
How I Got My Ticket for Free
I didn’t pay for this ride. While booking my flight, I came across a Jeju Air promo called “Korail Pass Flexible 2 Day in ‘Find Your Korea.'” To enter, you just named a place in Korea you wanted to visit and why. I wrote, “See you this November 2024, Seoul and Busan.”
A few days later, Jeju Air emailed to say I’d won, which I never expected. Here’s how it worked:
- Send my details: I emailed them so they could reserve the pass
- Confirm within two weeks: I had to confirm the reservation in that window
- Get my login: They sent a 5-digit password to access the pass on the Korail website
No payment, no catch, just a promo entry and some luck. You can read the full story in my Seoul to Busan guide.
My timeline:
- September 30: Booked my flight, right after my visa was approved
- October 24: Got the email saying I’d won
- October 30: Korail Pass reservation confirmed
- November 1: Trip started
Even with the win coming less than a week before departure, everything came together in time.

Journey Time & Best Departure Times
I booked the 7 AM KTX because it was the only fast train still available that morning. Most of the remaining trains were slower all-stop services, and the next direct KTX wasn’t until 9 PM. That would have put me in Seoul late at night, and I had an itinerary planned for that same morning, so the early departure made the most sense.
Tips for short-notice bookings:
- Direct and limited-stop KTX trains fill up fast
- An early departure is often your best shot at the fastest ride
- It also leaves you a full day to use once you arrive
What the KTX Ride from Busan to Seoul Was Like
It was my last day in Busan, but something told me I’d be back. The city had only begun to unfold its magic.
- Departure: Busan Station was wrapped in early morning quiet when I arrived with my luggage, somewhere between gratitude and anticipation. My 7 AM KTX was already waiting, sleek and ready to carry me north, and it left right on time.
- On board: Lush green fields, sleepy villages, and autumn-tinged landscapes rolled past my window. It wasn’t my first train ride in South Korea, but it was my first time returning as someone ready to simply be, not someone trying to see everything.
- Arrival: About two serene hours later, I stepped off in Seoul, one of my favorite cities in the world. The rush of announcements and footsteps was just as I remembered. The chaos hadn’t changed, but I had.
Two hours, one quiet train, and I was back in the city I love, a little more confident than when I left. Nothing beats watching Korea roll by from a train window, especially when you’re traveling solo and in no rush.
Arriving at Seoul Station: What to Expect
Straight off the KTX, I followed the signs to the Seoul Station subway. That was when it truly hit me: I was actually in Seoul.
Here’s how my Busan to Seoul itinerary looked on travel day: a 7 AM KTX, about two hours on the train, then the subway from Seoul Station to my guesthouse.
My route to the guesthouse:
- Subway: Line 4 from Seoul Station, Jinjeop-bound
- Get off at Hoehyeon Station, near my guesthouse.
- Exit: Exit 3 is the one I needed
I stepped out of Hoehyeon Station like a seasoned local, since I’d been here before, only to discover I’d taken the wrong exit. I came out at Exit 7 instead of Exit 3, which meant crossing the street with my luggage in tow for a slightly longer walk.
But Exit 7 had its perks:
- Yellow ginkgo trees lining the street
- A view of N Seoul Tower in the distance
- Walking distance to Myeongdong Street
Wrong exit, right kind of accident. It wouldn’t be a CJ trip without at least one navigation hiccup.
Where I Stayed in Seoul
Dream Guesthouse was the perfect base, and this was my second stay. It’s tucked in a prime spot, just steps from Hoehyeon Station.
Nearby:
- Namdaemun Market
- N Seoul Tower
- Myeongdong Night Market
Why I’d stay again:
- Kitchen and dining area: Squeaky clean and inviting, stocked with coffee, tea, and water
- Social vibe: A great spot to wind down after a full day or chat with fellow travelers
- Staff: The fatherly man at the front desk was warm, welcoming, and always ready to help.
Arriving before check-in? I reached my guesthouse around 11 AM, but check-in wasn’t until 2 PM. The staff happily stored my luggage in a locker with a key, so I headed out to explore right away. See what I did with the day in my solo travel in Seoul.
What I Wish I’d Known Before Taking the KTX
Standing on the platform at Busan Station, I felt that familiar wave of solo travel anxiety and double-checked my ticket and car number. It turned out the ride was remarkably smooth. Here’s what I’d tell you before you board:
- 🚅 Check the train type before booking: Not every train is a high-speed KTX. When seats sell out, slower ITX or Mugunghwa services show up as options and can add over two hours to your trip.
- ⏰ Arrive early: Give yourself time to find your platform and carriage and settle in stress-free.
- 🎟️ Skip the ticket barriers: I didn’t see turnstiles or gate inspectors at the station. I walked straight to my platform and boarded.
- 🧳 Board early for luggage space: Carry-ons fit overhead, while large suitcases go in the shared racks. Early boarding gets you a spot.
- 🤫 Keep it quiet: Carriages are peaceful. Keep your phone on silent, use headphones, and take calls in the vestibule.
- 🍱 Buy snacks beforehand: I didn’t see any food carts on board, so I picked up bread and coffee inside Busan Station.
- 🔌 Stay connected: There’s free Wi-Fi and power outlets under the windows.
- 🗺️ Plan your Seoul Station arrival: Map your next subway line, bus, or walk ahead of time so you aren’t figuring it out while hauling luggage through a busy station.
A little preparation makes solo travel feel effortless, so you can relax and enjoy the scenic ride.

How long is the KTX from Busan to Seoul?
About 2 hours 15 minutes on the fastest direct services, though some trains take closer to 2.5 hours depending on stops.
How much does the Busan to Seoul KTX cost?
Standard one-way fares run about $43–70 USD (₩59,000–95,000) in economy class, booked through the Korail app. I won mine free through a Jeju Air “Find Your Korea” promo; it’s worth checking if your airline runs anything similar when you book.
Is the KTX easy for solo travelers to navigate?
Yes. English announcements and signage are standard throughout Korean KTX stations, and seat reservations are assigned, so there’s no guesswork in finding your seat.
What’s the best way to get from Busan to Seoul?
The KTX is the fastest option at about 2 hours 15 minutes. Slower services like the ITX and Mugunghwa are also available, but they can add over two hours to your trip.
Where does the KTX arrive in Seoul?
At Seoul Station. From there, you can connect straight to the subway. I took Line 4 to Hoehyeon Station, where my guesthouse was.
What’s the difference between the KTX and ITX?
The KTX is the high-speed train with fewer stops. The ITX and other slower services stop more often, so the ride takes noticeably longer. When KTX seats sell out, these are the trains that show up as alternatives, so check the train type before you confirm.
What should a Busan to Seoul itinerary look like on travel day?
A morning departure leaves you a full day in Seoul. I took the 7 AM KTX, arrived with time for my planned itinerary, and mapped my subway route from Seoul Station ahead of time so I wasn’t figuring it out with luggage in hand.
Busan to Seoul by KTX: What It Taught Me as a Solo Traveler
Returning to South Korea as a solo female traveler taught me powerful lessons about growth, independence, and perspective. Traveling back to Seoul felt like meeting an old friend. The place stays steady. I notice the shift within myself. I wasn’t rushing anymore. I wasn’t trying to prove anything. I was simply present. And presence feels richer than ambition.
Some journeys present themselves as a collection of places: Busan, Seoul, train stations, guesthouses, and unfamiliar streets that slowly become familiar. But looking back now, I realize this trip was never just about moving across cities. It was about the quiet space between who I was when I left and who I became when I returned.
