Hagosudong Beach: Did You Know Its Water Rivals Seobinbaeksa?
as striking as Seobinbaeksa
Mention Udo Island and the first place that comes to mind for most people is Seobinbaeksa, the coral-sand beach. But there's said to be another beach on Udo whose water rivals Seobinbaeksa's — Hagosudong Beach. Sitting on the island's east side, it hasn't built up the same name recognition as Seobinbaeksa, but it's reportedly gaining a quiet following for its clear water and sunset views. Rather than covering the whole island again, GYULI is zooming in on Hagosudong Beach alone today, laying out what's known and being upfront about what isn't confirmed. The ferry schedule and how to get around Udo have already been covered in another article, so this time the focus stays entirely on Hagosudong Beach itself.
Where on Udo Is Hagosudong Beach?
Hagosudong Beach is said to sit on the eastern side of Udo. If Seobinbaeksa is the signature beach on the western half of an island loop, Hagosudong is reportedly the one you meet on the opposite, eastern side. Since the whole island falls under a single administrative unit, Yeonpyeong-ri, it's less about a precise street address and more about a beach you naturally come across while circling the island. Being relatively less known than Seobinbaeksa, it reportedly draws smaller crowds even during peak season, letting visitors enjoy a quieter atmosphere. That said, exactly how crowded it gets can vary by season and time of visit, so take this as general guidance rather than a guarantee.
The Water Said to Rival Seobinbaeksa
When people talk about Hagosudong Beach, the water color is never left out. The sea is described as an emerald-jade color that stays clear even in the shallows, said to offer a different kind of charm from the coral sand of Seobinbaeksa. On clear, sunny days the color reportedly stands out even more vividly, and quite a few reviews name it as one of the prettier photo spots on Udo. That said, water color can look quite different depending on the day's weather, tide, and season, so on a cloudy day or at the wrong tide, it may not match what you expected — worth keeping in mind ahead of time. The sandy area is said to be smaller than Seobinbaeksa's, though some say that smaller scale makes it easier to take in the whole beach at a glance. There's also talk of a wide shallow stretch, so quite a few visitors reportedly wade in and swim during summer — for exact depth and safety information, it's best to check on-site signage or staff directly.
Many say it's a shame to leave Udo having only seen the coral sand of Seobinbaeksa — Hagosudong Beach's water is said to be every bit as clear.
— 🍊 GYULIWhy It's Also Known as a Sunset Spot
One reason Hagosudong Beach comes up almost as often as its water color is the sunset. Many reviews describe the sky and sea turning red together at dusk as a striking sight, and it's said to come up often as a sunset spot for that reason. Some visitors reportedly time their trip for late in the day just to watch the water shift from its daytime jade color into something else entirely under the sunset light. That said, how vivid the sunset looks depends entirely on that day's weather and cloud cover, so if a sunset is the whole point of your visit, checking the forecast beforehand is the safer move. Udo reportedly has several spots mentioned together as sunset viewpoints, and among them, Hagosudong Beach is frequently singled out for letting you take in the water color and the sunset in the same place.
There are said to be a few cafes and basic amenities around Hagosudong Beach, but by most accounts it stays noticeably quieter than the areas around Seobinbaeksa or the Udo pier. Maybe that's why some visitors reportedly seek out Hagosudong on purpose, looking to enjoy the sea away from the crowds. There's also talk of a space nearby where camping is possible, though exactly how it operates or whether it's currently available can change by season, so it's hard to state anything definite here. Many travelers are said to fold Hagosudong Beach into their bike or electric-cart loop around Udo, so rather than stopping at Seobinbaeksa alone, it's worth making the extra trip out east. More than one review repeats the same idea — that Udo feels far richer when you sit for a while, taking in the water and the sunset by turns, instead of just snapping a quick photo and moving on.
GYULI's Tip · Hagosudong Beach's water color and sunset are said to look different every time, depending on weather, tide, and season. If you're planning to pair it with Seobinbaeksa in a single day trip, build in generous travel time and check the sunset time beforehand.
