Korea Trekking, Exploring Gogunsan Archipelago: Sunyudo & Munyodo Island Trekking Review & Course Guide
 |
| Exploring Gogunsan Archipelago |
Scattered across the azure ocean like a handful of emerald jewels, the islands of the Gogunsan Archipelago are a place you’ve likely heard of at least once. Truth be told, I used to think of them as distant islands best appreciated from afar. But setting foot on them transformed my perspective entirely-there’s an incredible charm to hopping from one island to another on foot across ocean-spanning bridges.
Let me take you on a coastal journey through Sunyudo and its neighboring islets, where every step comes with the salty breeze and boundless sea views.
🌊 Gogunsan Archipelago
Nestled off the coast of Gunsan in Jeollabuk-do, the Gogunsan Archipelago is a stunning cluster of roughly 60 islands. While reaching them once required a ferry ride, today they are seamlessly connected to the mainland via the Saemangeum Seawall and the Gogunsan Bridge.
With emerald-tinted West Sea waters framed by dramatic rock formations, it stands as one of the ultimate coastal trekking destinations on Korea's western coast.

Munyodo Jjittongseom & Ttongseom Coastal Trail
Crossing the Munyo Bridge into the village entrance, you’re instantly greeted by a refreshing sea breeze. Jjittongseom Islet-accessible only when the tide parts the waters-offers a magical front-row seat to the rhythms of the tides. The tidal flat scenery winding past village alleys retains all the cozy, peaceful charm of a rural island town.
Sunyudo Mangjubong Peak & Okdol Beach
As you enter Sunyudo, the towering twin rock spires of Mangjubong Peak capture your gaze with their overwhelming presence. The white sandy expanse of Sunyudo Beach set against Mangjubong makes an unbeatable backdrop for photos, while the wooden boardwalk along Okdol Beach-where smooth pebbles chime with every rolling wave—serves as the true highlight of the trek.

📍 Recommended Munyodo–Sunyudo Route
Starting near the entrance of Munyodo and stretching toward Sunyudo Beach and the entrance to Jangjado, this core route spans roughly 8 to 10 km (3 to 4 hours). Thanks to gentle inclines, wooden boardwalks, and paved paths, even beginners can enjoy a comfortable hike.

📍 Honest Visit Review
Walking the Munyodo–Sunyudo trail was a delightful treat, blending ocean vistas, island vibes, and mountain peaks all into a single journey. The transition from Munyodo’s quiet fishing-village ambiance to Sunyudo’s grand rock faces and vibrant beaches created a thrilling contrast.
As you near Sunyudo Beach, Mangjubong’s twin peaks rise majestically in the background. Couples strolled along the water's edge, kids built sandcastles, and speedboats cut through the waves-everyone soaking up the soft autumn sunlight and ocean energy at their own pace.
At high tide, the waters creep right up to the base of Mangjubong, creating a crystal-clear reflection like a mirror. This massive monolith is the iconic symbol of Sunyudo, accompanied by a legend of an exiled noble couple who climbed the peak every day to gaze toward the king, eventually turning into stone.
Mangjubong
Reaching the Daebong Observatory treats you to a sweeping view of the open West Sea, a maze of scattered islets, and a bright blue sky filled with floating clouds. Though Daebong reaches only about 100 meters above sea level, its central position on the island makes the panorama feel utterly boundless.
Note that the stretch from Daebong over to Namaksan Mountain follows an unmaintained mountain path scattered with loose rocks and boulders, so watch your footing. As I trekked along the ridge, the sun began its slow descent, painting the sky in warm amber hues.
Because large shade trees are scarce along the coast, midday during peak summer could be quite intense. I strongly recommend visiting during spring or autumn, or planning your trek for early morning or late afternoon when the golden light sets in.
