Table of Contents
The First Thing Every Gangneung Trip Runs Into
"I tried to book the KTX but everything's sold out." — This is the most common thing I hear from people planning a Gangneung trip, and honestly, it used to catch me off guard too. The train sells fast, especially on weekends and during peak seasons like cherry blossom time or summer. I remember scrambling for tickets when I took my kid to Gangneung — it was a whole process.
In this post I'm covering everything you need to get from Seoul to Gangneung smoothly: how to book KTX tickets, what to do when it's sold out, the updated cancellation fee rules that changed in May 2025, family car options for traveling with kids, and the foreign tourist taxi service that makes getting around Gangneung much easier once you arrive. Whether this is your first time or you're helping a friend plan the trip, this covers everything in one place.
Seoul → Gangneung KTX — The Basics
There are a few ways to get from Seoul to Gangneung, but for international visitors the KTX is the clear recommendation every time. It's fast, comfortable, and completely predictable — no traffic, no transfers, straight to Gangneung Station.
Seoul → Gangneung KTX at a glance
Departure stations: Seoul Station or Cheongnyangni Station (Cheongnyangni is faster)
Arrival station: Gangneung Station
Journey time: approx. 1hr 50min–2hrs (shorter from Cheongnyangni)
Fare: Standard class approx. ₩27,600 / First class approx. ₩38,500 (varies by train/time)
Frequency: 10+ trains per day (extra trains added during peak seasons)
Departing from Cheongnyangni Station shaves about 10–15 minutes off the journey compared to Seoul Station. If you're staying in eastern Seoul or near the subway line 1 corridor, Cheongnyangni is the more convenient option. If you're coming from the Gangnam side, Suseo Station offers SRT — but note that SRT doesn't run to Gangneung, so KTX is the standard route for this destination.
How to Book — Korail Talk App & Letskorail Website
KTX tickets are booked through two main channels: the Korail Talk app (smartphone) and the Letskorail website (letskorail.com). Both are available in English and accept international credit cards, so foreign visitors can book directly without going to a ticket counter.
Booking tip
KTX tickets go on sale exactly one month before departure at midnight Korean time. Weekend and holiday trains to Gangneung can sell out within minutes of opening. If your travel date is set, mark the booking open date on your calendar and be ready to book the moment it opens.
Why Weekends Sell Out & How to Get Cancellation Tickets
Weekend KTX trains to Gangneung are genuinely competitive — during cherry blossom season, summer weekends, and public holidays, popular departure times can sell out within minutes of going on sale. But selling out doesn't mean it's over. Cancellation tickets come up more often than people expect.
When people's plans change, they cancel — and those seats go back into the system immediately. The most productive windows for finding cancellation tickets are 1–2 days before departure, and on the morning of travel itself (6–8am tends to see a surge as people who slept in and missed their plans let go of their tickets). Checking the app regularly during these windows and being flexible on departure time by an hour either way makes a real difference.
How to catch cancellation tickets — practical tips
Bookmark your preferred train in the Korail Talk app for quick access
Check most intensively 1–2 days before departure — highest cancellation volume
6–8am on travel day is another surge window — last-minute plan changes
Stay flexible on time — if your preferred train is gone, check 1 hour either side
Cancellation alerts: in Korail Talk, select a sold-out train → tap 'Cancellation Ticket Notification' to get alerted when seats open
KTX Cancellation Fees — Updated May 2025
KTX cancellation fees were revised on May 28, 2025. The biggest change affects weekend and public holiday tickets — fees increased significantly, especially for same-day cancellations. If you're booking a weekend train, it's worth understanding these before you commit.

Weekend & public holiday cancellation fees (revised May 28, 2025)

Weekend cancellation — key things to know

Cancelling within 3 hours of a weekend departure costs 20% of the fare — on a ₩27,600 standard ticket, that's around ₩5,500. One workaround: the 'Travel Change' feature lets you move to a different time on the same day for free, up to 3 hours before departure (one change per ticket).
Traveling with Kids — Family Cars & Child Fares
Taking the KTX with kids is much easier than most people expect. I took my child to Gangneung by KTX and the family car made a real difference — it's a designated carriage where families with young children can be a bit more relaxed without feeling like they're bothering other passengers. Everyone around you is in the same situation, which changes the whole atmosphere.
What to know when traveling KTX with kids
Family car: available on select KTX trains — choose 'Family Seat' when selecting seats during booking
Infant fare (under 6): free if sitting on a parent's lap / 50% of adult fare if occupying a seat
Child fare (ages 6–12): 50% of adult fare
Strollers: foldable strollers permitted, use overhead or designated luggage areas
Nursing space: available on some KTX trains — check Korail Talk before booking
Window seats: strongly recommended with kids — watching the scenery makes the journey much easier
The family car isn't available on every train — it runs on certain KTX services only. When selecting your seat during booking, look for the 'Family Seat' option in the seat map. On weekends, family car seats fill up quickly, so booking early applies here too. Window seats on the Gangneung line pass some great scenery as you get closer to the coast, which helps keep kids entertained for the last stretch of the ride.
Getting Around Once You're in Gangneung
Once you step off the KTX at Gangneung Station, the next question is: how do you actually get around? Gangneung's major attractions are spread across the city center, the coastline, and outlying areas like Jeongdongjin and Jumunjin. Public buses exist but run infrequently on some routes. For first-time visitors especially, this is where knowing about the foreign tourist taxi makes a big difference.
Foreign Tourist Taxi — Full Gangneung Tour for ₩30,000
The Gangneung foreign tourist taxi is an officially run service operated jointly by Gangwon Province and Gangneung City. It launched in 2019 as the first program of its kind among Korean local governments, and it's grown significantly since — in 2024, Gangneung accounted for 79% of all foreign tourist taxi rides in Gangwon Province, with over 7,500 riders that year alone.
The way it works: the local government subsidizes half the cost, so tourists pay just ₩30,000 per person for a 3–4 hour tour hitting 3–4 locations. Drivers speak enough English, Chinese, or Japanese to communicate, and they'll guide you through each stop. The most popular course by far is the BTS K-Wave Tour — centered on the Jumunjin Bus Stop from the BTS Spring Day music video — and the demand from international visitors is what drove the program's growth through social media word of mouth.
How to use the Gangneung foreign tourist taxi
Cost: ₩30,000 per person (government subsidized — half the actual fare)
Capacity: up to 4 passengers per taxi
Booking: on-site at Gangneung Station information desk, or in advance online
Platform: Gangwon Tourist Taxi official site (gangwontaxi.com) or walk-in at Gangneung Station
Languages: drivers available in English, Chinese, and Japanese
Duration: typically 3–4 hours covering 3–4 locations
Tourist taxi — things to know before you go

Other Ways to Get Around
Beyond the tourist taxi, there are several other options for moving around Gangneung depending on your itinerary and comfort level.

Final Thoughts — How to Prep for Gangneung
The two things that make or break a Gangneung trip before you even arrive are getting your KTX ticket and knowing how you'll get around once you're there. Book the train as early as you can — ideally the moment the one-month window opens. If you miss it, work the cancellation ticket system. And once you're in Gangneung, the foreign tourist taxi is genuinely one of the best deals in Korean travel right now: ₩30,000 per person, a driver who knows the spots, and three to four locations covered in one go.
For anyone traveling with kids, the family car on the KTX is worth specifically booking for. My kid's face watching the East Sea come into view through the train window for the first time is still one of my favorite travel memories. That moment alone is worth the trip.
