Twice a Day, a Path Opens — Seogeondo Island's Sea Road
a walking path only at low tide
Hi, I'm GYULI, the tangerine sprite who's lived on Jeju's oreum for a hundred years. Today I want to introduce a very small island said to sit along Jeju's coast. It's called Seogeondo, and most of the time it's said to look like just another little island floating across the water. But at a certain time of day, a path is said to appear that lets people walk right over to it — and when I first heard that, my eyes went wide thinking, 'wait, a path opens up over the sea?' Today I want to slowly walk through the story behind Seogeondo, along with a few things worth knowing if you're thinking about visiting.
Twice a Day, a Path Said to Open Across the Sea to Seogeondo
Seogeondo is said to be a small uninhabited island floating not far from the Jeju coastline. At high tide, it's said to simply look like an island sitting across the water, but as the tide goes out, a path made of rocky reef and gravel is said to gradually appear between the island and the shore. Once this path is fully exposed, you're said to be able to walk all the way across to the island, though you might have to accept getting your shoes a little wet along the way. And as the tide starts coming back in, the path that appeared is said to slowly sink back beneath the water, returning the island to its usual look, cut off from the shore.
What's interesting is that this sea path is said to open not just once but about twice a day. Because tides rise and fall roughly twice daily along the coast, there are said to be about two windows a day when the water pulls back enough, and each time, the path is said to briefly appear. That said, it's said not to reveal itself to the same degree every time — depending on how far the water recedes, some days the path is said to appear wide open, while other days it barely peeks out before disappearing again. So even visiting the same Seogeondo, the scenery you encounter is said to look completely different depending on the day and time you go.
Why It's Nicknamed 'Jeju's Miracle of Moses'
Because of the way the sea seems to part and pull back to reveal the path, Seogeondo is often introduced as 'Jeju's Miracle of Moses.' The nickname is said to come from how the sight recalls the biblical scene of the sea parting to open a path, and some say that once you actually watch the rocky path gradually emerge as the water recedes, it's easy to see why the comparison stuck. I haven't seen it in person myself yet, but even just imagining a path slowly emerging from between the waves feels pretty mysterious to me.
Watching the seawater slowly pull back to reveal the path, people often say they finally understand why it's called the Miracle of Moses.
— 🍊 GYULIThat said, because of this nickname, you might be a little disappointed if you go expecting the sea to part dramatically like in the story every single time. In reality, the width and condition of the exposed path are said to vary with the tide and weather — on some days it's said to open up generously, while on others the water doesn't recede quite as much and only part of the gravel path is walkable. So I want to be careful about saying something as definite as 'go at this exact time and you're guaranteed to see this path,' and it's worth keeping in mind that the scenery can change day by day depending on the tide.
Why Checking the Tide Beforehand Really Matters
Since the path to Seogeondo is said to open only while the tide is out, checking the tide schedule ahead of time is probably the single most important thing to prepare if you're planning a visit. If you arrive before the water has receded enough, the path may not be exposed at all, and you could end up turning back without ever reaching the island. On the other hand, if you lose track of time while out on the path, the rising tide is said to be able to submerge your way back before you know it. I can't state an exact time here with certainty, but I'd recommend checking that day's tide table before you go and giving yourself plenty of buffer time.
Personally, I find scenery that only appears when the timing lines up just right to be even more special. It would be convenient if a place looked the same no matter when you showed up, but there's something more memorable about checking the tide, timing your visit, and then actually watching the path reveal itself in front of you. That said, since it's a rocky coastal path, it can be slippery or leave your feet wet, so staying safe matters more than rushing to catch the exact moment. Since the window during which the path stays exposed is said to be fairly short, it's worth leaving yourself plenty of buffer time for taking photos or looking around the island. And if the water starts showing signs of creeping back in, it's said to be safer to head back promptly, even if it feels a little rushed.
GYULI's Tip · Since Seogeondo is said to be walkable only while the tide is out, checking the tide schedule before you go is essential. The exact timing is said to change day by day, so look up that day's tide table in advance, and even while the path is exposed, keep an eye on when the tide is due to turn so you can head back with plenty of time to spare. The rocky path can be slippery when wet, so don't forget comfortable, non-slip shoes.
