Complete Guide
Hike above the South Sea, cross a tidal path to Lighthouse Island, and discover one of Tongyeong’s most dramatic small-island landscapes. Somaemuldo is compact, steep and unforgettable.
A small island
with a dramatic edge
Somaemuldo travel is defined by one unforgettable scene: a green lighthouse island rising beyond steep cliffs, connected to the main island by a narrow path that appears only when the tide is low enough.
The island itself is small, but the terrain is surprisingly active. From the harbor, walking paths climb through the village and continue toward viewpoints above the sea, where jagged rocks and nearby islands fill the horizon.
The highlight is Deungdaeseom, often called Lighthouse Island. When sea conditions and tide timing allow, travelers can cross the exposed path and continue toward the lighthouse. Because the crossing depends on the tide, timing matters more here than on most island trips.
How to Get to
Somaemuldo
Somaemuldo can be reached by passenger ferry from the Tongyeong area and from Geoje. The best route depends on your mainland itinerary, but the most important part of planning is to match your ferry schedule with the tide.
Tongyeong or Geoje
Choose the mainland departure point that best fits your overall travel route. Tongyeong is a natural base for travelers exploring several islands in the area, while Geoje can also provide access to Somaemuldo.
Plan Around Low Tide
The sea path between Somaemuldo and Lighthouse Island is exposed only when the tide allows. Check the tide for your actual travel date before deciding which ferry to take.
Leave Enough Time
Do not plan the lighthouse crossing too close to your return ferry. The island involves climbing, walking and waiting for suitable tide conditions.
Travel date → tide window → round-trip ferry → lighthouse route → village stop → final ferry check.
Getting to Somaemuldo
Ferry times and routes can change by date, season and sea conditions. Check the latest ferry information together with the tide before traveling.
6 Highlights of
Somaemuldo
Somaemuldo is less about collecting attractions and more about following one continuous island landscape from harbor to cliff, tidal path and lighthouse.
Deungdaeseom Island
This small island is the defining image of Somaemuldo. Green slopes, rocky cliffs and the white lighthouse create a scene that feels almost detached from the busier mainland coast.

At low tide, the sea retreats enough to reveal a narrow rocky route between Somaemuldo and Deungdaeseom. Walking this temporary path is one of the island’s signature experiences.
View on Google Maps →Somaemuldo Lighthouse
The lighthouse stands on Deungdaeseom above the open South Sea. Reaching it after crossing the tidal path makes the lighthouse feel like the natural destination of the entire hike.
View on Google Maps →Mangtaebong Viewpoint
Climb above the village for one of the best elevated views toward Lighthouse Island. This is where the relationship between Somaemuldo, the cliffs and the sea becomes clearest.

Jagged rocks and layered coastal cliffs give the island much of its character. Several naturally shaped rock formations can be seen around the island and surrounding sea.

The small harbor village is where every trip begins and ends. Narrow lanes climb away from the water, giving the first hint that this island is much steeper than it appears from the ferry.

A Classic 1-Day
Somaemuldo Itinerary
Somaemuldo works very well as a day trip if your ferry and low-tide window line up. Keep the itinerary simple: lighthouse first, village second.
On Somaemuldo, do not build the day around lunch or sightseeing stops first. Set the lighthouse crossing around the safe low-tide window, then arrange everything else around it.
Getting Around
Somaemuldo
Somaemuldo is a walking island. Once you leave the ferry, the experience is built around village paths, uphill trails and the tidal crossing.
Walking
Walking is the primary way to explore Somaemuldo. The harbor, village, viewpoints and Lighthouse Island route are all connected on foot.
Expect steep sections soon after leaving the harbor. Keep your luggage light if you are visiting for the day.
Island Trail
The main hiking route links the village with Mangtaebong and continues toward the sea crossing. It is short enough for a day trip but physically more demanding than a flat coastal walk.
Give yourself extra time for climbs, descents and photo stops.
Tidal Crossing
The crossing to Lighthouse Island is not ordinary transportation. It is a temporary route created by the tide and should be treated as a timed part of your itinerary.
Cross back before the safe window ends. Never assume the path will remain open because it was visible when you arrived.

Before You Travel
to Somaemuldo
Somaemuldo requires more timing than most small island trips. Check both the ferry and the tide before committing to your route.
The lighthouse crossing should be the first fixed point in your itinerary.
Expect uphill paths, uneven trails and rocky coastal sections.
Prepare before leaving the main harbor area for the trail.
Much of the island is explored entirely on foot.
Leave enough time to cross back safely before the sea path disappears.
Sea conditions can affect island routes, so confirm the latest sailing status before leaving the mainland.
Planning Somaemuldo?
Check the ferry and tide together.
Somaemuldo is not just about getting to the island. Your ferry needs to match the low-tide window if you want to cross to Lighthouse Island. Check both before building the rest of your day.
Continue your
Tongyeong island journey
After hiking Somaemuldo and crossing toward Lighthouse Island, continue exploring Korea’s South Sea with SEOMITTA’s English island guides. Start with nearby Tongyeong islands, then discover more islands across the southern and western coasts.
Climb above the harbor,
then walk where the sea disappears
Somaemuldo turns a small island into a surprisingly complete adventure. The village climbs into a trail, the trail opens to cliffs, and finally the sea itself becomes a road.
Build your Somaemuldo travel itinerary around the tide, give yourself enough time for the climb, and make Lighthouse Island the centerpiece of the day. On this island, timing is part of the landscape.
