Korea Just Opened Its First Coast-to-Coast Trail: Inside the 850KM Dongseo Trail
Anmyeon Island to Uljin, 55 sections, and 90 villages putting out food and a spare bed for anyone willing to walk the whole way across the peninsula.
For most of my life, "hiking in Korea" meant one thing: a crowded weekend scramble up Bukhansan with half of Seoul, everyone in matching neon jackets. The Dongseo Trail is a completely different animal, and honestly, it's the first Korean trail project I've seen that's actually being compared — seriously, by international outlets — to the Camino de Santiago.
The name gives it away: Dongseo (동서) simply means "east-west." Instead of looping around a single mountain, this route does something Korea has never attempted at this scale — it connects the west coast to the east coast in one continuous line, cutting straight through the middle of the country instead of around it.
The Trail, By the Numbers
Full completion is expected by the end of 2026, with unrestricted public access rolling out through 2027. But here's the part most first-time visitors don't realize: you don't need six weeks off work to experience it. Sections 1 through 4 on the western half are already open and walkable as standalone day trips or long weekends, and that's genuinely the smarter way to try it before committing to more.
Trail planners modeled this deliberately after the Camino de Santiago and Japan's Kumano Kodo — not for the scenery alone, but for the infrastructure philosophy. Instead of building new resorts, the Korea Forest Service is routing hikers directly through 90 existing rural villages, giving small communities a reason to stay open rather than empty out. That's a very different tourism model than the theme-park version of "attraction" most guides push.
The Route: What You Actually Walk Through
This isn't a straight line on a map so much as a slow diagonal drift across the peninsula, and it deliberately skips Seoul entirely — which is exactly what makes it interesting.
Anmyeon Island, Taean (West Start)
The western trailhead sits on a pine-covered island about three hours from Seoul by bus or car, opening straight onto tidal flats and fishing harbors on the Yellow Sea.
Sejong & Daejeon (Midlands)
The trail cuts through inland forests, Buddhist temple grounds, and centuries-old Confucian schools — the stretch travel writers keep singling out as the emotional core of the walk.
Uljin, North Gyeongsang (East Finish)
The eastern trailhead ends on the rugged East Sea coastline, about four hours from Seoul, in a town better known among Koreans for its winter crab season than for hiking — until now.
The Food Is Half the Reason to Go
I'll be blunt: for a lot of Korean hikers I've talked to, the trail's appeal isn't just the walking, it's what's waiting at the end of each section. The 90 designated rest villages aren't generic pit stops — they're built around whatever that region is already known for.
West Coast: Tidal Flat Seafood
Taean and the islands around Anmyeondo are tidal-flat country, which means clams, blue crab, and grilled fish caught the same morning show up on nearly every rest-stop menu near the trailhead.
East Coast: Uljin's Snow Crab Season
Finish the trail in autumn or early winter and you land right in Uljin's daege (snow crab) season — arguably the single best-timed payoff of any long-distance trail I've come across anywhere in Asia. A bowl of daegemulhoe, cold raw snow crab in a tangy chilled broth, tastes like a reward you actually earned.
Hit the trail in October or November and street vendors near the rural rest stops sell roasted chestnuts (gunbam) and warm sujeonggwa, a spiced cinnamon-persimmon punch, straight out of pushcarts. It's small, it's cheap, and it's exactly the kind of detail no official brochure mentions but every hiker remembers.
Planning Your Own Walk
You don't need to be an ultra-hiker to make this work. Spring (April-June) and fall (September-November) are the recommended windows — which, conveniently, means right now is close to ideal timing if you're reading this in September. Single-day sections near Anmyeon Island or Uljin are the easiest entry points, while multi-day stretches through Sejong and Daejeon suit anyone wanting a real test without committing to all 55 sections.
Along the route, five information offices and 15 shelters handle cooking and overnight stays, alongside the village guesthouses, so you're rarely more than a day's walk from a hot meal and a real bed — no wild camping gear required unless you want it.
What actually convinces me this trail will last, rather than fade into another underused government infrastructure project, is that it doesn't ask small towns to build anything new. It just asks hikers to show up and spend money on what's already there — a guesthouse, a crab dinner, a bowl of soup from someone's grandmother. That's a far more sustainable model than most "new mega-attraction" tourism pushes I've seen announced in Korea over the years.
🎯 Key Takeaways
- The Dongseo Trail is Korea's first coast-to-coast route, running 849km across 55 sections from Anmyeon Island to Uljin.
- Full completion lands by late 2026, but western sections are already open for day trips and long weekends right now.
- The trail deliberately routes through 90 rural villages, pairing the hike with regional food — West Coast tidal-flat seafood and East Coast snow crab season.
A trail this new is still being written by the people who walk it first. Korea has plenty of famous mountains and even more famous cities, but this might be the first route built specifically to slow visitors down and push them into towns most travelers would otherwise never have a reason to see.
