The Dongseo Trail is South Korea’s first coast-to-coast hiking route — 849 km from the Yellow Sea to the East Sea, opening in 2026.

South Korea has had great day hikes for years. The Jeju Olle Trail, Bukhansan above Seoul, the ridgelines of Seoraksan. All excellent, all well-documented. What it hasn’t had is a true transcontinental long-distance trail. A proper coast-to-coast. Something you could spend six weeks walking, or carve into weekend pieces, that crosses the entire width of the country.

That changed in September 2025 when the first four sections of the Dongseo Trail opened. And by the end of 2026, the whole thing should be walkable: 849 kilometers from Anmyeon Island on the Yellow Sea to Uljin on the East Sea. West coast to east coast. Fifty-five sections. The Camino de Santiago of East Asia, except nobody outside Korea has heard of it yet.

In one sentence: South Korea’s first coast-to-coast trail crosses the peninsula in 55 hikeable sections, and it’s still new enough that you’ll have it to yourself.

Why This Makes the List

Because someone finally connected the dots.

South Korea is smaller than many people realize (roughly the size of Indiana). But it packs absurd geographic variety into that space: volcanic coastline, terraced rice valleys, dense mountain forests, Buddhist temples tucked into ridgelines, and fishing villages where the catch still comes in before dawn. The problem has always been that hiking in Korea meant individual trails. Point-to-point day hikes. No continuous route that took you through the full spectrum.

The Dongseo Trail fixes that. It’s a single waymarked route from the western shore to the eastern shore, passing through 90 designated base camp villages along the way. The design is deliberately modular — 55 sections, each roughly 12–20 km, each meant to be walkable in a day. You can do a weekend in the mountains outside Daejeon. Or a week of coastal walking near Uljin. Or the whole 849 km over 40–50 days.

And here’s the part that matters for the bucket list: South Korea has some of the best hiking infrastructure in Asia. Trail shelters, clean water sources, convenience stores in even the smallest towns, and a transit network that can get you to trailheads with a bus card and minimal Korean. The Jeju Olle Trail proved that Korea could build a world-class long-distance route. The Dongseo Trail is the mainland answer, at four times the scale.

What’s Open Right Now

The first four sections — 57 kilometers total — opened in September 2025, concentrated in the central mountainous zone. These are the test bed. The trail association used them to work out waymarking standards, camping logistics, and the base camp village system before scaling to the full route.

As of March 2026, trail construction is moving outward toward both coasts. The government’s target is full completion by the end of 2026, though some sections may open progressively through the year. This is similar to how the England Coast Path rolled out — functional but still finishing, with most sections walkable before the official “done” date.

For international hikers planning a trip in 2026, the practical window is late summer through autumn. By September or October 2026, enough sections should be open to walk a substantial coast-to-coast route, even if a handful of gaps require short bus transfers.

What 849 Kilometers Across Korea Looks Like

The Western Start: Anmyeon Island

The trail begins on Anmyeon Island, a coastal area known for pine forests and tidal flats on the Yellow Sea. It’s a quiet start — fishing culture, salt farms, sunsets over mudflats that turn gold at low tide. About three hours from Seoul by bus, so no long-haul logistics to reach the trailhead.

The Central Mountains

The middle sections cross the Chungcheong and Gyeongsang highlands. This is where the trail gets vertical — forested ridgelines, Buddhist temple stays, river gorges. Korea’s interior mountains are steep but not high (most peaks under 1,500 m), and the trail follows established paths where it can. Expect 600–1,000 meters of elevation gain on the more demanding days.

These central sections are also where the 44 official camping sites cluster. The base camp village system means you’re alternating between tent nights and village stays, which keeps pack weight manageable.

The Eastern Finish: Uljin Coast

The trail ends at Uljin on the East Sea (Sea of Japan). The eastern coast is the dramatic payoff — rocky shoreline, clear water, seafood markets, and hot spring towns. If you’ve been walking for weeks through the interior, hitting the ocean feels earned.

Uljin itself is a mid-sized coastal town with bus connections to Busan (3 hours) and Seoul (4 hours by express bus). Not a glamorous endpoint, but a real one.

How the Dongseo Trail Compares

The Camino comparison is inevitable, so here’s how it stacks up against the trails people actually know.

	Dongseo Trail	Camino de Santiago	Jeju Olle Trail
Distance	849 km	~800 km	437 km
Sections	55	~33 stages	27 routes
Daily cost	$30–$60	€40–€70	$40–$70
Crowds (2026)	Almost none internationally	400,000+/year	Moderate, mostly Korean
Accommodation	Base camp villages + camping	Albergues, hostels	Guesthouses, hotels
Terrain	Coast, mountains, valleys	Rolling hills, meseta	Coastal, volcanic
Transit access	Excellent (Korea’s bus/rail)	Good (Spain’s rail)	Limited (island buses)

The biggest difference is modularity. The Camino has a clear start (St. Jean Pied de Port) and finish (Santiago). You walk the whole thing or a recognized section. The Dongseo Trail is built more like the Jeju Olle — pick your sections, mix and match, come back for more. That design reflects how Korean hikers actually use trails: weekend warriors outnumber thru-hikers by a huge margin.

The Real Costs

Money

South Korea is more expensive than Southeast Asia but cheaper than Japan for hiking. On the Dongseo Trail, your daily budget looks roughly like this:

• Camping (official sites): Free to ₩10,000/night ($7)
• Village guesthouse/minbak: ₩30,000–₩60,000/night ($22–$44)
• Temple stay (where available): ₩50,000–₩80,000/night ($37–$59), includes meals and meditation sessions
• Meals: ₩8,000–₩15,000 ($6–$11) at village restaurants. Convenience store meals for ₩3,000–₩5,000
• Daily trail budget: $30–$60/day depending on accommodation choices

For a two-week section hike, expect $600–$1,200 on the trail, plus flights.

Getting there: Round-trip flights to Seoul (Incheon) from the US West Coast run $600–$900. From Europe, $500–$800. Once you’re in Asia — if you’re already visiting Japan or chasing cherry blossoms in Korea — the trail is a bus ride away.

Time

The full traverse takes 40–50 days at a steady pace with rest days. But the modular design means you can do it in pieces:

Option	Sections	Days	What You Get
Weekend taster	2–3 sections	2–3	Mountain or coastal flavor
One-week trip	5–7 sections	6–8	A full regional crossing
Two-week deep dive	12–15 sections	12–16	Coast-to-mountains or mountains-to-coast
Full thru-hike	All 55	40–50	The whole peninsula

If you’re combining with other travel in Korea or Japan, a week on the trail fits neatly into a longer East Asia trip. You don’t need to build your entire vacation around it.

Physical Demands

Moderate, with caveats. The central mountain sections involve real climbing — 600–1,000 m of elevation gain in a day isn’t casual, especially in Korean summer humidity (July–August, when the monsoon also arrives). The coastal and valley sections are gentler.

If you can handle a day hike with 800 meters of elevation gain and a 15 kg pack, you can do this trail. Prior multi-day hiking experience helps but isn’t strictly necessary for section hikes.

The biggest physical variable is heat. May–June and September–October are the sweet spots. July and August bring monsoon rain and oppressive humidity that turns moderate hikes into survival exercises. I’ve hiked Bukhansan in August. Once was enough.

How to Make It Happen

Step 1: Decide Your Format

Weekend section near Seoul? One-week mountain crossing? Full thru-hike? The 55-section design means you don’t have to commit to more than you have time for. Start with a section hike and come back for more if it hooks you.

For first-timers to Korea, combining 5–7 trail sections with a few days in Seoul and a side trip (Busan, the DMZ, a temple stay) makes the most of the flight.

Step 2: Time It Right

• April–June: Spring bloom, moderate temperatures, clear skies. Cherry blossom season (late March to mid-April) overlaps with early trail conditions
• July–August: Monsoon season. Hot, humid, rainy. Skip unless you enjoy suffering
• September–November: Autumn color season. The Korean mountains in October are genuinely spectacular — maples and ginkgos turning the ridgelines red and gold. This is the prime window
• December–March: Cold. The central mountains get snow. Possible but not pleasant without winter gear

Step 3: Sort Logistics

Fly into Seoul (Incheon). From there, Korea’s KTX high-speed rail and intercity bus network can reach any trailhead within 3–4 hours. The western terminus at Anmyeon Island is roughly 3 hours by bus from Seoul. The eastern terminus at Uljin is about 4 hours.

Get a T-money card at any convenience store. It works on buses, subways, and trains across the country. Korea’s transit system is one of the best in Asia — frequent, affordable, and labeled in English at major stops.

Accommodation: For base camp villages, the trail association is developing a booking system. For nearby towns, Korean booking apps (Yanolja, Goodchoice) have more options than international platforms. Google Translate handles Korean menus and booking pages well enough.

Step 4: Pack for Korean Trail Conditions

• Trail shoes with good grip (Korean mountain trails are often steep, rocky, and root-covered)
• Rain jacket and pack cover (rain is possible April through November)
• Layers for mountain sections — ridgeline weather changes fast
• Portable battery pack. Waymarking will partly rely on a trail app, and your phone is your map
• Cash in Korean won for small villages, though Korea is increasingly card-friendly even in rural areas
• Minimal Korean helps: 감사합니다 (gamsahamnida — thank you) and pointing at menu items covers 90% of interactions

What Are the Best Sections of the Dongseo Trail?

Since the full trail is still completing in 2026, definitive “best of” lists don’t exist yet. But based on the route map and the sections that have opened:

1. The initial 4 sections (57 km): The first segments opened, in the central highlands. Mountain forest, temple areas, proof-of-concept for the full trail
2. Anmyeon Island coastal start: Tidal flats, pine forests, fishing villages. A gentle opening that builds momentum
3. Central mountain crossing near Daejeon: The backbone of the route, where the peninsula’s spine requires real climbing
4. Uljin coastal finish: East Sea drama — rocky coast, seafood towns, hot springs to soak the trail out of your legs
5. Any section connecting a temple stay: Korea’s Templestay program lets you overnight at Buddhist temples along the route. Meditation at dawn, mountain hiking by 8 AM. Hard to replicate anywhere else

Pro Tips

Don’t skip convenience stores. Korean convenience stores (CU, GS25, 7-Eleven) are on another level. Hot meals for $4, decent coffee, emergency supplies, phone chargers, and they’re in almost every village. They’re your resupply infrastructure.

Consider a temple stay. The Korean Templestay program operates at temples throughout the mountains. Roughly $40–$60 per night including vegetarian meals, evening chanting, and 4:30 AM wake-up bells. It’s not luxury accommodation. It’s something better — one of those experiences that justifies having a bucket list in the first place.

Learn the shelter system. Korean mountain trails often have basic shelters (산장, sanjang) at higher elevations. These aren’t staffed huts like in the Alps — more like three-walled structures with a roof. Useful for lunch stops and emergency shelter. The Dongseo Trail’s official camping sites should be a step up from these.

Autumn color is peak. If you can only go once, go in October. Korean autumn is short — roughly three weeks of peak color moving south down the peninsula — but the mountain sections of the Dongseo Trail in fall foliage will be the trail’s signature image once photographers discover it.

Bus connections are your friend. Unlike the Via Transilvanica where guesthouse-to-guesthouse is the main mode, the Dongseo Trail benefits from Korea’s bus network. If a section doesn’t appeal or weather turns bad, you can bus ahead and pick up a better stretch. Flexibility is built in.

Alternatives to Consider

Lower Commitment Version

The Jeju Olle Trail on Jeju Island is the established version of Korean long-distance hiking. 437 km in 27 routes around the volcanic island, with years of infrastructure behind it. If you want the proven experience rather than the new frontier, Jeju is the answer. It pairs well with cherry blossom season in late March.

Different Asian Long-Distance Trail

Japan’s Kumano Kodo pilgrimage routes offer a similar mix of culture, mountains, and spiritual infrastructure. Shorter (the most popular route is about 70 km over 4–5 days), more expensive, more polished. If the Dongseo Trail is the Camino before the crowds, the Kumano Kodo is the Camino after — beautiful, well-run, and busy in peak season.

Pair It With More Asia

Korea sits between Japan and China with cheap flights to both. A week on the Dongseo Trail connects naturally with time in Tokyo, Osaka, Taipei, or Shanghai. If you’re planning a sabbatical year or extended Asia trip, the trail slots in as the physical anchor of a longer itinerary.

Go Solo

Korea is one of the safest countries in the world for solo travelers. Crime rates are negligible, the transit system is navigable without Korean, and the trail’s base camp village system means you’re never far from help. Solo hiking here carries less logistical risk than almost any equivalent trail in Europe.

Is This For You?

Probably yes if:

• You’ve done a Camino or similar trail in Europe and want the Asian equivalent
• You’re drawn to Korean culture — temples, food, rural village life — and want to experience it at walking pace
• Modular design appeals to you. You want a trail you can do in weekends or weeks, on your schedule
• You like being early. The trail is new, the international hiking community hasn’t arrived, and the first thru-hike reports will be written by whoever goes in 2026
• You’re already visiting East Asia and can add a week without a separate flight

Probably no if:

• You need extensive English-language trail resources and a community of international hikers at every stop. Those don’t exist yet
• You want a fully completed, well-documented trail with years of hiker reports. Come back in 2028
• Korean summer humidity would ruin your trip (if you can only go July–August, reconsider)
• You’re looking for wilderness remoteness. Korea is densely populated; even rural trail sections pass through villages regularly

The Bottom Line

The Dongseo Trail is what happens when a country with world-class hiking infrastructure decides to connect its coasts. 849 kilometers, 55 sections, 90 base camp villages, and a design that says: do it your way. Walk a weekend. Walk a week. Walk the whole thing.

Right now, in early 2026, the trail is still being built. That’s either a reason to wait or a reason to go. By 2027 or 2028, there’ll be English-language guidebooks, YouTube series, and forum threads ranking every section. The trail will be the same, but the feeling of walking something nobody’s written about yet — that’s a 2026 thing.

South Korea is 3–4 hours from Seoul by bus at either end. It doesn’t require a separate expedition. If you’re in Asia, it’s a detour. If you’re not, it’s a reason to be.
