Travel Guide
A mysterious sandbar that appears only at low tide, peaceful beaches and easy mountain viewpoints. Daeijakdo is one of Incheon’s most rewarding islands for travelers who want nature, walking and a slower overnight escape.
Follow the tide
to a disappearing island
Daeijakdo Island is a small island in Ongjin County, west of Incheon. It is best known for Puldeung, a vast sandy shoal that appears in the middle of the sea when the tide recedes and disappears again as the water returns.
The island is not only about Puldeung. Four beaches, forested mountain trails and viewpoints overlooking nearby islands make Daeijakdo especially rewarding for travelers who enjoy combining the coast with easy hiking.
Buasan Mountain is the most accessible viewpoint, while Songisan Mountain offers a longer walk. Along the western coast, Keunpul-an and Jakeunpul-an beaches provide quiet places to swim, walk or simply watch the changing tide.
How to Get to
Daeijakdo Island
A Daeijakdo Island trip begins with checking the passenger ferry from Incheon. Your ferry schedule determines how much time you actually have on the island, so confirm both outbound and return sailings first.
Choose Your Travel Date
A day trip may work if your ferry schedule allows enough time, but Daeijakdo is best enjoyed over 1 night and 2 days. This gives you more flexibility for tides, beaches and hiking.
Check the Ferry
Check passenger ferry services connecting Incheon with Daeijakdo. Departure times and operating conditions may vary by date, season and weather, so always use the latest information.
Check the Tide for Puldeung
Puldeung is visible only when the tide is low. If seeing the sandbar is a priority, check the tide table before arranging the rest of your island itinerary.
Choose your date → check the round-trip ferry → check the tide → book accommodation → plan beaches and hiking → confirm ferry operations again on departure day.
Check the ferry from Incheon
Daeijakdo is reached by passenger ferry from the Incheon area. Rather than planning around fixed times, check the latest schedule for your exact travel date. Ferry services can be affected by weather and sea conditions.
Best Places to Visit
on Daeijakdo
The island’s highlights are concentrated around its changing tidal landscape, peaceful beaches and low mountain ridges. Puldeung is the signature sight, but it is worth leaving time for the rest of the island.
Puldeung Sandbar
Puldeung is Daeijakdo’s most famous natural landmark. As the tide falls, a huge sandy shoal appears in the sea before disappearing beneath the water again. Its shape and size change with the tide, making every visit slightly different.
View on Google Maps →Buasan Mountain
Buasan rises to about 159 meters and is one of the easiest scenic hikes on the island. A relatively short climb leads to viewpoints overlooking the West Sea and nearby islands including Seungbongdo, Soijakdo and Deokjeokdo.
View on Google Maps →Keunpul-an Beach
Keunpul-an is one of Daeijakdo’s broadest beaches. A long stretch of firm, fine sand follows the western coast, creating an easy place for swimming, walking and spending a quiet afternoon beside the sea.
View on Google Maps →Jakeunpul-an Beach
Jakeunpul-an sits next to Keunpul-an with a rocky coastal section between the two. The beach has a quieter atmosphere and is also a good area for viewing the changing coastal landscape around Puldeung.
View on Google Maps →Songisan Mountain
Songisan rises to about 188 meters and forms the island’s main east-west ridge. It is a good choice for travelers who want a longer walk than Buasan and enjoy combining forest trails with sea views.

Daeijakdo
1 Night 2 Days
The best itinerary depends on the tide. Treat the low-tide window for Puldeung as the fixed point in your schedule, then arrange beaches and hiking around it.
If Puldeung is your main reason for visiting, check the tide before deciding which day or time to hike Buasan. The sandbar should take priority over a fixed sightseeing order.
Getting Around
Daeijakdo
Daeijakdo is small enough for slow travel, but beaches, mountain entrances and the ferry terminal are spread across the island. Plan transportation according to how much walking you want to do.
Local Transportation
Local transportation is useful for covering the longer distances between the ferry terminal, villages and major beach areas.
Island transportation can be limited, so check current operating information before relying on it for a tight schedule.
Vehicle
A vehicle is useful if you want to connect multiple beaches, mountain trailheads and village areas during a short stay.
If bringing a vehicle, confirm vehicle boarding availability and reservation requirements for your ferry.
Walking & Hiking
Walking is the best way to enjoy Buasan, Songisan and the coastal areas around the beaches.
Use transportation for longer connections and save your walking time for the mountain and coastal sections.
Is Daeijakdo
Right for You?
Daeijakdo works especially well for travelers who enjoy natural landscapes, gentle hiking and quiet island nights.
Puldeung is one of the most distinctive tidal landscapes around Incheon and changes dramatically with the sea.
Buasan offers a relatively short climb, while Songisan provides a longer option for travelers who want more time on the trail.
Keunpul-an and Jakeunpul-an offer spacious coastal scenery without the atmosphere of a large resort beach.
Daeijakdo is particularly rewarding when you stay overnight and let the tide, sunset and morning landscape set the pace of the trip.
What to Check Before
Visiting Daeijakdo
Puldeung and ferry access are both strongly connected to sea conditions, so a little preparation makes a big difference when traveling to Daeijakdo.
Confirm your round-trip ferry before planning the rest of the trip.
Check the tide table if Puldeung is one of your priorities.
Bring comfortable walking shoes if you plan to hike Buasan or Songisan.
Check local transportation if you are visiting without a vehicle.
Reserve accommodation in advance for an overnight trip.
Confirm the latest ferry operation again on your departure day.
Planning a trip to Daeijakdo?
Check the ferry and tide first.
Start with your round-trip ferry, then check the tide for Puldeung. Once those two times are fixed, it becomes much easier to arrange beaches, hiking and an overnight stay.

Wait for the tide
and watch an island appear
Daeijakdo is a place where the sea decides the rhythm of the trip. At low tide, Puldeung appears in the water. A few hours later, the same landscape can look completely different.
Between tides, walk the beaches, climb Buasan and look across the West Sea toward neighboring islands. There is no reason to rush.
For your Daeijakdo Island trip, start with the ferry and tide table, then let the island fill in the rest of the day.
