White sand and black rock,
facing Sanbangsan

Hi everyone, it's GYULI, the tangerine sprite who's called Jeju's oreum home for a hundred years. A while back I told you about Sanbangsan and then Hyeongjeseom, one after another, and both of those stories happened to start around the same spot — Sagye-ri, Andeok-myeon, Seogwipo. In the Sanbangsan piece I focused on the bell-shaped volcanic landform itself, and in the Hyeongjeseom piece I focused on the two islets said to float offshore. But I realized I'd never properly told you about the place where you actually stand to take in both of those views — Sagye Beach. So today, let's set Sanbangsan and Hyeongjeseom aside for a moment and focus only on the beach that holds that scenery.

A Beach Where White Sand and Black Rock Meet

Sagye Beach is known to sit in Sagye-ri, Andeok-myeon, Seogwipo. Jeju is said to have plenty of beaches with fine white sand, and plenty of rocky coastlines covered in black basalt, but Sagye Beach is said to be a place where you can meet both faces in one spot. One side of the beach is said to stretch out in soft sand, while the other is said to be lined with a wide expanse of black rock worn smooth by the waves — so even within the same beach, the scenery underfoot is said to change completely depending on where you walk.

The area covered in black rock in particular is said to be submerged or exposed depending on the tide, so many accounts say the beach's mood can feel quite different depending on when you visit. When the tide is out, people are said to enjoy slowly walking across the black rock terrain and peering into tide pools, while when the tide comes in, the rocks are said to disappear beneath the waves, creating an entirely different atmosphere. Being able to see a different face each time you visit is reportedly one reason people keep coming back to Sagye Beach.

A Spot Facing Sanbangsan and Hyeongjeseom

One reason Sagye Beach is often mentioned as a photo spot is that standing on the beach is said to let you take in both Sanbangsan and Hyeongjeseom within a single view. When I told you about Sanbangsan, I focused on the bell-shaped volcanic mass itself, and when I told you about Hyeongjeseom, I focused on the two islets floating side by side at sea. Sagye Beach can be thought of as the place where the white sand and black rock spread out in front of both of them as a backdrop — so maybe it's fair to call it the stage from which you view the mountain and the islands.

Especially when the tide goes out and reveals a wide stretch of sand, some say the wet sand surface reflects the sky and Sanbangsan's silhouette like a mirror. It's a style of photography often called a reflection shot, said to capture Sanbangsan upside down on the damp, still sand — which is apparently why Sagye Beach comes up so often among people who enjoy photography. That said, this reflection isn't said to appear clearly every time; it's said to depend on that day's tide, weather, and how wet the sand is, so it's probably best to take this as a general reference rather than a guarantee.

I told you about Sanbangsan and Hyeongjeseom separately, but it turns out this beach is the one spot that lets you face both of them at once.

Why the Beach Is Said to Look Different Depending on the Tide

The reason the tide comes up so often when people talk about Sagye Beach is that both the black rock terrain and the reflection photos mentioned earlier are said to change a great deal depending on how far the tide has gone out. When the tide is far out, a much wider stretch of sand and rock is said to be revealed than usual, and when the tide comes in, the walkable area is said to shrink accordingly. So if you'd like to take a leisurely walk across Sagye Beach, many suggest checking that day's tide schedule ahead of time before you go.

That said, the areas covered in black rock are said to sometimes have moss or slippery surfaces, and some accounts describe them as more precarious to walk on than expected. It's probably worth wearing comfortable shoes and watching your footing as you move slowly across them, and if you're visiting with kids, it's said to be worth paying extra attention to when the tide is coming in.

Looking at it this way, Sagye Beach feels less like a place defined by one clear landmark, the way Sanbangsan or Hyeongjeseom are, and more like a scene completed by the white sand, the black rock, and the silhouettes of the mountain and islets visible beyond them, all coming together. If you enjoyed the Sanbangsan and Hyeongjeseom stories, this time I'd recommend actually setting foot on Sagye Beach, the stage behind those stories. Within the same Sagye-ri, Andeok-myeon, you can take in all three scenes — the mountain, the islets, and the beach — one after another.

GYULI's Tip · The area of exposed rock and how clearly the reflection shots turn out at Sagye Beach are said to depend on the tide, so it's worth checking that day's tide schedule before you visit. The black rock terrain is said to have slippery surfaces, so don't forget to wear comfortable shoes.

At Sagye Beach the white sand and black rock sit right next to each other, so the scenery underfoot keeps changing as you walk. They say you can see both Sanbangsan and Hyeongjeseom from right here, so if you love photography, you really have to come see it!
