A Visit to Biyangdo, the Hidden Island on Jeju’s West Coast
.
There is a small island on the western side of Jeju called Biyangdo.
Biyangdo sits off the coast of Hallym-eup in Jeju City. Its name means “an island that flew down from the sky.” The island is located just 1.1 km from Hallym Port, and its shape is nearly circular. Around 2,000 residents live here.
At the center of the island stands Biyangbong Peak, rising 114 meters above sea level. On the western coast, you’ll find Jeju’s largest volcanic bombs—massive rocks formed during past eruptions.
On the northern coast, about 20 chimney-shaped rocks called hornitos are scattered along the shoreline. These natural formations were created when lava met water in wetlands, blasting upward like a fountain and solidifying. They have been designated Natural Monument No. 439.
On the eastern side lies Peolleongmot Wetland and a village shrine. While Biyangdo was once believed to have erupted about 1,000 years ago, scientific analysis of lava samples shows it was actually formed around 27,000 years ago.

If you enter “Jeju Coast Guard Hallym Station” into your navigation, you’ll arrive at Hallym Port. From the ticket office on the right side of the terminal, you can purchase your ferry ticket to Biyangdo.

Looking out from the port, you’ll see the island in the distance, sitting gracefully on Jeju’s sparkling blue waters. The sea here is so clear and bright that just gazing at it lifts your spirits.

While waiting for the ferry, I set up two simple fishing rods with shrimp bait. Despite the effort, I didn’t catch even a small bite that day. Still, the strong May sunshine and lively atmosphere at the port kept things enjoyable.

The ferry was full—it was the weekend, after all. I struck up a conversation with a local elder who visits Biyangdo every week to fish. He shared such a lively introduction to the island that the short trip felt even more exciting.

Exploring the Island
Once you arrive, head left from the harbor, and you’ll soon spot Olle Coffee Shop, a charming blue café with Jeju vibes. Order a drink and you can also rent a bicycle to explore the island. The owner is cheerful and welcoming—a real character you’ll enjoy meeting.
Interestingly, many of the bicycles used around the village belong to Olle Coffee, but locals happily share them. It reflects the close-knit community spirit of the island.

You can even feel the unique Jeju charm of Biyangdo in its stone walls.
At the entrance, the island’s guardian statue, “Biyangi,” welcomes visitors—though not with the warmest expression.

I recommend enjoying a cool drink, then hopping on a bike to circle the island. Along the way, you’ll find picturesque views, rustic stone walls, and even the island’s symbolic guardian statue—though it doesn’t exactly greet visitors with a smile.
Half a day is enough to fully explore Biyangdo, making it a perfect addition to your Jeju itinerary.

Natural Wonders of Biyangdo
The western coast of the hornito area is home to Jeju’s largest volcanic bombs, some measuring up to 4 meters in diameter and weighing as much as 10 tons. These colossal rocks were ejected during eruptions and piled around old volcanic vents.
Geological studies suggest that while Biyangbong is the island’s main peak, another vent once existed offshore. Today, the sea has eroded much of it away, leaving only these giant volcanic bombs behind.

A Family-Friendly Destination
Biyangdo is wonderful for families, couples, and anyone looking for a scenic getaway. Children can enjoy the bike rides and island atmosphere, while parents can take in the views—or try a little fishing.

On my visit, I spent most of my time fishing rather than touring the entire island. The catches were small, but it was fun. I returned the little fish back to the sea, promising myself to come better prepared next time.

On the way back, I even saw the elder I met earlier fishing off the breakwater. He caught a sizable rockfish but released it back, likely because it wasn’t the target species. Watching his skill reminded me that real anglers play by their own rules..

Final Thoughts
My first visit to Biyangdo was on a friend’s recommendation, but now I plan to return every time I visit Jeju. It’s a small island with a big charm—stunning views, warm locals, and a touch of geological wonder.
If you ever travel to Jeju, don’t miss the chance to visit Biyangdo. It may just become the highlight of your trip.
