Sokcho, on Korea's north-eastern coast and the gateway to Seoraksan National Park, is one of the country's most popular weekend escapes — and one of the few major domestic routes with no direct train. The express bus is the standard way to get there, and it is fast and comfortable enough that almost nobody minds.
Why there is no train
Unlike Busan or Daegu, Sokcho sits on a stretch of coastline that the KTX and conventional rail network do not reach directly — a legacy of Korea's mountainous eastern geography and historically limited rail investment along the East Sea coast. There has long been talk of extending high-speed rail further up this coastline, but for now, road transport is how everyone gets to Sokcho, and the road network here is genuinely good. For the parts of the country the network does cover, see the South Korea by train guide.
This is not unusual by regional standards — plenty of well-visited destinations across Asia sit outside the reach of high-speed rail and depend on coaches instead, in the same way that Delhi to Manali in the Indian Himalayas or several routes deep into Vietnam's central highlands rely on long-distance buses rather than trains.
The standard way: the express bus
Frequent express and intercity coaches run from Seoul's major bus terminals — primarily the Express Bus Terminal and Dong Seoul Terminal — to Sokcho, taking around 2 hours 30 minutes to 3 hours depending on traffic and the exact route through the mountains via the Seoul–Yangyang Expressway. Buses are modern, air-conditioned, and run regularly throughout the day, more so at weekends and during the busy autumn foliage and winter ski seasons when Seoraksan draws crowds.
Book ahead online or through a ticketing app for weekend and holiday departures, as popular services can sell out, particularly in autumn when the maple colours on Seoraksan peak. On a quiet weekday, turning up and buying a ticket at the terminal is usually straightforward. Tickets are assigned to a specific seat and departure, similar to the reserved-seating conventions on Korea's KTX trains, so there is no need to queue for a place — just for the ticket itself.
Two classes of coach typically run this route: standard express buses with normal reclining seats, and premium or deluxe services with wider seats and more legroom for a modest extra fare. On a journey pushing three hours each way, the upgrade is often worth it, especially if you plan to hike in Seoraksan the same day and would rather arrive rested.
Driving to Sokcho
The drive covers around 190 km and takes about 2.5–3 hours via the Seoul–Yangyang Expressway, a scenic route that tunnels and winds through the Taebaek mountain range before dropping to the coast. Having a car is genuinely useful once you arrive, since Seoraksan's various entrances and the coastal towns around Sokcho are spread out and not all well served by local buses. Expect much heavier traffic — sometimes doubling the journey time — on Friday evenings and Sunday afternoons in peak season, and especially during the Chuseok and Lunar New Year holidays, when this corridor is one of the most congested in the country.
A hire car with an International Driving Permit is straightforward for foreign visitors to arrange in Seoul, and having one afterwards is useful if you plan to continue further up the coast toward Sokcho's neighbouring towns or south along the scenic coastal road rather than heading straight back to Seoul.
Reaching Seoraksan National Park
Sokcho itself is a small city; most visitors are really headed for Seoraksan National Park, whose main entrance (Seoraksan Sogongwon) is about a 20–30 minute local bus ride from central Sokcho or the bus terminal. Local city buses run regularly between the terminal, downtown Sokcho and the park entrance, so you do not need your own transport once you arrive by coach. Sokcho's fish market and beachfront are also an easy walk or short taxi from the terminal if you want a night in the city itself before heading up to the park the next morning.
Flying: not practical
Yangyang International Airport serves the wider area with limited flights, mostly seasonal and often oriented around domestic charter or tour groups rather than a reliable year-round schedule to Seoul. For a Seoul–Sokcho trip specifically, flying makes little sense: the express bus is faster door-to-door once you account for getting to an airport, and it goes right into the city.
Which should you choose?
For almost every traveller, the express bus is the answer — frequent, comfortable, reasonably priced, and requiring no navigation once aboard. Only drive if you want the flexibility of a car for exploring Seoraksan's various trailheads and the coastal road beyond Sokcho, in which case budget extra time for peak-season traffic.
Sokcho is often combined with a wider loop around Korea's east coast, or treated as a contrast to the country's fast, rail-based trips covered elsewhere on this site — a reminder that even a country with excellent high-speed rail still leans on buses for its more mountainous corners. If you are arriving in Korea from abroad, start by checking the Seoul airport to the city guide for getting from Incheon into central Seoul before heading onward to Sokcho, and see the road hub for more on how Korea's bus network operates generally.
