Only a few minutes into the coastal deck walk, the view opened across the sea and small islands of the Gogunsan Archipelago.
FIRST-HAND KOREA COASTAL WALK · SEONYUDO
I only had a short break during a business trip to Gunsan, but a roughly 15-minute walk near Okdol Beach turned into one of the most memorable views of the trip. The trail follows the rocky coastline with the sea and small Gogunsan Islands constantly in view.

If you are already visiting Seonyudo, I would make time for at least a short walk on the Okdol Beach coastal deck trail.
I walked for only about 15 minutes, but that was enough to see rocky coastline, small islands, Seonyubong Peak and the pebble beach.
You do not need to complete the full Gogunsan walking route to enjoy this section.
Is this Okdol Beach Trail or Gogunsan-gil?
You may see several names for this area.
The coastal section beside Okdol Beach is officially described as the Beach Deck Promenade or 해변데크산책로.
It also forms part of the broader Gubul Route 8 — Gogunsan-gil, a much longer walking route across the Gogunsan Islands.
The important distinction is that I did not walk the entire long-distance route.
I only walked the short coastal deck section near Okdol Beach.
You can enjoy this place without planning a full hike. My short section took about 15 minutes and still gave me plenty of sea views.
The scenery changes as soon as you drive into Seonyudo
Seonyudo is now connected by road, so I drove onto the island during my Gunsan business trip.
Once I crossed into the Gogunsan Islands, the scenery changed quickly.
Instead of city roads, small islands started appearing one behind another across the water.
My schedule was still a work schedule, but the weather was too good to simply look through the car window and leave.
My route: parking area → breakwater → whale sculpture → deck trail
After parking, I walked toward the breakwater.
Near the start of the coastal trail, there was a silver whale sculpture.
From around that point, the deck follows the coastline.
It initially looked like a simple short promenade, but after only a few minutes, the view opened dramatically.

I walked for roughly 15 minutes rather than completing the whole trail.
Small islands appear directly in front of the trail
This was the point where the walk became much more impressive than I expected.
The deck sits close to the rocky coastline, and small islands seem to float directly in front of you.
The official tourism information for this area also highlights the unusual rock formations and coastal geology.
On the day I visited, the clear sky made the colors of the sea, islands and clouds unusually vivid.
Samdo Gwibeom
One of the traditional scenic views around Seonyudo is Samdo Gwibeom — 삼도귀범.
It refers to three small islands that were traditionally imagined as three sailing boats returning to port.
Knowing that story changed the way I looked at the islands.
What initially looked like three ordinary small islands suddenly had a name and an old local interpretation attached to them.
The deck runs directly above the rocky coast
My favorite section was where the deck follows the rock face with the sea immediately outside the railing.
Below the walkway, the coastline is made up of layered and irregular rocks.
There were also stairs leading down toward some of the rocks.
I saw quite a few people fishing around the rocks and breakwater.
If you leave the deck or approach fishing areas, check local warning signs and sea conditions. Wet coastal rocks can be much more slippery than the main walkway.
Okdol Beach is a pebble beach, not a sandy beach
Okdol Beach is a small beach in Seonyu 1-gu.
The Korean word 옥돌 literally refers to smooth jade-like stones.
Instead of a wide sandy beach, the shore here is covered with rounded, smooth pebbles.
That makes it visually different from the main Seonyudo Beach.
It also means I would not treat it exactly like a comfortable barefoot sand beach.
Water shoes would be more practical than bare feet on a pebble shoreline. This is mainly my practical impression from seeing and walking around the beach, not a requirement.
Parking is the part I would plan carefully
The official local tourism information specifically warns that parking near the Seonyu 1-gu trail is limited.
That was not a serious problem during my own short visit, but I would expect the situation to be very different on a summer weekend or holiday.
Do not plan your schedule assuming you can park immediately beside the trail entrance. Allow extra time during peak season, weekends and Korean public holidays.

What international visitors should know
- Search the Korean name: 옥돌해변 데크 산책로. It gives better results in Korean navigation apps.
- This article covers a short walk, not the full Gogunsan-gil hiking route. My actual walk was only around 15 minutes.
- A car is convenient for this itinerary. Seonyudo is connected by road, but parking becomes the important issue once you arrive.
- The beach is pebble-covered. Do not expect the same surface as Seonyudo's main sandy beach.
- The route is not completely step-free. The wider area includes changes in level and stairs toward coastal rocks, so it is not a route I would assume is wheelchair-friendly.
- Weather matters. Strong wind, rain or rough sea conditions can make a coastal walk much less comfortable.
- There is no admission ticket for the short public coastal walk. Parking or other local services may have separate charges depending on where you use them.

Was 15 minutes really enough?
For me, yes.
I was not trying to complete a hike. I simply wanted to get out of the car and see the coast properly before returning to work.
In only a short walk, the scenery changed between sea, small islands, rock formations, the deck and Seonyubong Peak.
That made the stop feel much longer than it actually was.
