Nueseom Island: Silkworm-Shaped Island Only Accessible Twice A Day By Walking Across The Sea

Nueseom Island


Nueseom Island in Ansan is named affectionately after its shape, that resembles a silkworm. Although the island seems just out of reach as it sits in the middle of the ocean, you can actually access it at certain times of the day. 


A path that only appears twice a day

To get to the island, you have to first locate Ansan Tando Port. Then, keep a lookout for a path that disappears into the waters. It should be pointing in the direction of a row of windmills located on an island in the middle of the sea.

You’ll wonder how to get to the island if you’re visiting during high tide. But when low tide rolls around twice a day, a concrete path that leads to the Nueseom Island and the windmills will reveal itself. Daily low tide timings are updated monthly by the staff.

The now-exposed sea floor along the path itself is a sight to behold, and it is home to various tiny sea creatures.

You’ll have to pay to walk on the tidal flats, and it costs KRW9,000 (~USD6.90) per adult, and KRW7,000 (~USD5.30) per child.

You can even try your hand at harvesting oysters if you pay KRW10,000 (~USD8) per person. Buckets are provided, but you’ll probably want to make sure you’re dressed in the appropriate gear because you’ll get muddy all over.

The scale of the windmills, coupled with the unique setting, will provide a one-of-a-kind backdrop for the photos you take here.

Watch out for a giant humanoid sculpture named “K” along the path that looks almost as tall as the windmills from certain angles.

At the end of the concrete path stands Nueseom Island itself. Despite its tiny size, the island boasts some amazing scenery of the neighbouring islands and the ocean beyond.

One of the first things that greets you once you set foot on Nueseom Island is this art installation dubbed the “바람과 춤추는 물고기”, which translates to “Fishes that dance with the wind”. Each fish represents a species of fish that inhabits the surrounding waters of the island.

Despite its small size, the island also has elevated platforms that you can trek up to catch beautiful views of the island itself, its windmills, as well as mainland.

The observatory has a dedicated lighthouse exhibit on the first floor that shares about Nueseom Lighthouse Obervatory’s own history, as well as about lighthouse-related information in Korea.

The second floor is a rest area, and there are counters with chairs that you can rest at sip drinks and enjoy the sea view.
