Seoul to Sokcho: Bus, Train and Car Options for Seoraksan and the East Coast (2026)

Searching for a Seoul to Sokcho train and finding nothing is the first surprise of planning a trip to the east coast. There is no direct KTX or regular train between the two cities in 2026, and the high-speed line that would change that is still being built. The practical answer is the bus, with a KTX-plus-bus combination and a rental car as the alternatives. This guide explains which one suits which kind of trip, where to board in Seoul, and how to avoid the worst of the autumn crowds heading for the mountains.

If you want the bigger picture of what to do once you arrive, our Sokcho and Seoraksan guide covers the town, the beaches and the park itself. Here we stay on the journey.

Why There Is No Train to Sokcho Yet

The Chuncheon–Sokcho high-speed line is still under construction, and reports from early 2026 point to an opening postponed to around the end of 2029, later than the earlier 2027 target. The Gangneung–Jejin section of the east coast line is also not open and is reported as delayed to roughly the same period. Plans and dates can shift — confirm on the official site before building a trip around any future line. For now, any itinerary that starts with a train to Sokcho will not work.

What does work is simple. Express and intercity buses leave Seoul all day, the journey is a little over two hours, and the fare is modest. If you have never used Korea’s long-distance coaches, our guide to express and intercity buses explains how the two bus classes differ, and navigating Korean bus terminals helps you decode the signs and ticket counters.

The Bus: Your Default Choice

Most visitors should take the bus from Seoul Express Bus Terminal in Gangnam, which is served by Metro Lines 3, 7 and 9. The ride to Sokcho takes about 2 hours 10 minutes to 2 hours 30 minutes, with about 2 hours 20 minutes being the figure most sources quote. Fares are roughly 17,000 won for standard, about 22,000 won for deluxe and about 29,000 won for premium seating (as of 2026 — verify on the official KOBUS site before visiting). Deluxe and premium coaches have wider reclining seats, which is worth the extra money if you plan to sleep on the way back after a long hike.

Departures are frequent. Counts vary by season, but expect roughly 40 to 49 services a day, from around 06:00 until close to midnight (times can shift — confirm on the official site). That frequency is the reason the bus beats every other option for flexibility: if you miss one, another leaves soon after, at least outside peak periods.

Two Seoul Terminals, and Which to Pick

Seoul has a second option that many travellers overlook. Dong Seoul Terminal, by Gangbyeon Station on Metro Line 2, runs intercity buses to Sokcho with roughly 34 departures a day and a journey of about 2.5 hours, sometimes closer to 3 (as of 2026 — verify on the official site before visiting). Standard fares are in a similar range to the Gangnam service, and tickets are sold through apps such as T-money TxBus and Bustago. There is also a smaller express service from Dong Seoul, with fewer trips and an earlier last bus.

The terminal choice tip is practical rather than clever. Pick the terminal closest to where you are staying, because a 30-minute metro ride across the city can cancel out any time saved on the coach. Gangnam suits people sleeping south of the river or arriving from a Line 3, 7 or 9 transfer, and it has the later last departures, so it is the safer pick for a return trip you may not want to rush. Dong Seoul suits those staying on the east side of the city, though its last bus runs earlier — check carefully before planning an evening return.

Arriving in Sokcho: Two Terminals

Sokcho has two terminals, the Express Bus Terminal and the Intercity Bus Terminal, and they are not in the same place. Check your ticket for the arrival terminal before you board, since the wrong one adds a taxi or a bus transfer. Seoul Express services generally arrive at the express terminal, while Dong Seoul intercity services arrive at the intercity terminal.

From either terminal you can reach the park on Sokcho city bus 7 or 7-1, which run to the Seoraksan Sogongwon (Small Park) stop at the park’s entrance area in about 30 to 40 minutes. Fares are under 2,000 won and payment is usually by T-money card or cash (as of 2026 — verify on the official site before visiting). Route 7-1 serves the intercity terminal and the medical centre, while route 7 goes via Yeongnang-dong; the outbound service of route 7 ends earlier in the evening, so do not rely on it for a late return. Daytime frequency is roughly every 17 to 34 minutes combined.

Alternative: KTX to Gangneung, Then a Bus

If you like trains, or you want to add a coffee stop on the way, take KTX from Seoul or Cheongnyangni to Gangneung Station. The ride takes about 1 hour 50 minutes to 2 hours 5 minutes, with an economy fare of roughly 27,600 won (as of 2026 — verify on the official site before visiting). From Gangneung, an intercity bus covers the remaining stretch to Sokcho in about 1 hour 10 minutes, roughly every 30 minutes. Book KTX through KORAIL and the bus through KOBUS or Bustago.

Door to door this is usually slower than the direct bus, so it is not a time saver. It does make sense for people who want to split the trip, spending a few hours in Gangneung before continuing north. Our guide to Gangneung’s coffee and coast lists places worth stopping for, and KTX train guide for first-timers covers booking and boarding if it is your first high-speed train.

Driving: Freedom With a Catch

A rental car gives you the most freedom for the wider east coast, including beaches and fishing ports that buses reach slowly. Our guide to renting a car in Korea explains licences, insurance and navigation apps. The catch is the road itself: on busy days the approach to Seoraksan can slow to a crawl, and parking near popular trailheads is limited. For a trip focused only on the national park, the car is rarely the best tool.

Day Trip or Overnight? Who Each Option Suits

• Day trip by bus: workable for fit, early-rising travellers who take a morning coach and head straight to the park. With a journey of over two hours each way, you will have only a few hours on the trail.
• One night in Sokcho: the better choice for most people. You arrive rested, hike properly, eat seafood by the harbour and return the next day without watching the clock.
• KTX plus bus: suits travellers who want to combine Gangneung and Sokcho in one trip.
• Rental car: suits groups, families with luggage, and anyone planning to drive further along the coast outside peak weekends.

If you are choosing between a day trip and an overnight stay, we recommend the overnight in nearly every case, particularly between mid-October and early November.

Autumn Weekends: Plan Around the Crowds

Autumn is the main reason people ask about this route. The Korea Forest Service forecast puts Seoraksan’s peak colour, when about half the leaves have changed, at around 20 October in 2026, with first colour reported in late September. Forecasts can move with the weather, so check the latest update before you commit. For a wider look at the season, see our guide to autumn foliage in Korea and our notes on hiking seasons in Korea.

Local authorities run special traffic management around the park from early October to early November 2026, including a traffic control centre in Seorak-dong, free shuttle buses between the car-park districts and the Small Park, and stricter parking enforcement on the Yangyang side (dates can shift — confirm on the official site). The message is clear: on peak weekends, public transport plus the shuttle is faster and less stressful than driving.

Peak Saturdays and Sunday afternoons sell out. As a rule of thumb, buy your return ticket two to three days ahead, and four to five days ahead for a peak Saturday (as of 2026 — verify on the official site before visiting). Travel on a weekday if you can.

A Local Tip for the Return Leg

Buy your return coach ticket before you hike, not after. Sunday evening queues at Sokcho’s terminals can be long, and the last good departures fill early. If your preferred time is gone, a premium or deluxe coach later in the evening is often the only seat left, so book through the app on your phone while you still have signal on the trail’s lower sections.
