Gimnyeong Beach: Water So Clear, Your Eyes Feel Refreshed
over a wide sandy shore
When talk turns to Jeju's east coast, Gimnyeong Beach in Gujwa-eup is a name that comes up often. Thanks to water frequently described as emerald-toned and clear, and a wide stretch of white sand, it's said to be introduced as a beach representing Jeju's east coast — with many accounts noting it carries a different feel from Hyeopjae out west or nearby Hamdeok. Today GYULI is laying out what's said about Gimnyeong Beach, being upfront about what isn't confirmed. If you're planning a trip to Gujwa-eup, it's worth reading through to the end. The name Gimnyeong reportedly comes up often when planning an east-Jeju itinerary, and many visitors say they first learn about it while planning a trip that also includes nearby Manjanggul Cave or Woljeongri.
Gujwa-eup's Gimnyeong: Why It's Called Emerald
The phrase that comes up without fail when people talk about Gimnyeong Beach is "emerald sea." The water is said to be clear enough for sunlight to pass through well, and many accounts describe the color ranging from jade-like tones to deep emerald depending on the angle, weather, and time of day. Reviews repeatedly mention that the color looks more vivid on clearer days, though GYULI can't pin down the exact best time and weather conditions with certainty, so that's as far as this goes. The beach itself is also said to be on the wider side for Jeju's east coast, meaning finding a spot even during peak summer reportedly isn't too difficult. Many reviews describe the sand as fine and soft, often introduced as a beach that's pleasant to walk barefoot. Some also note that the same spot can look different depending on the tide and the intensity of the sunlight, so repeat visitors reportedly come away with a different impression each time.
A Wide Beach Often Recommended for Families
With its wide stretch of sand, many accounts say Gimnyeong Beach is worth visiting for a walk along the shore alone, not just for swimming. The shallow stretch is said to extend widely, which is reportedly why the beach is often recommended for families traveling with kids. That said, water depth and wave conditions can shift with the tide and weather, so if you're there with children, be sure to check the day's conditions with lifeguards or posted notices before going in. Details like parking, amenities, and shower facilities can reportedly shift a bit by season and by who's managing the site, so it's worth confirming the latest information before you go. Some say the beach gets crowded with summer swimmers, while others note that visiting relatively early in the day can mean a quieter atmosphere — though exact crowd levels can vary by date and time, so take this as general reference only.
Many say Gimnyeong's sand is as wide as its water is clear, so there's no need to worry about finding a spot — going early reportedly makes it even quieter.

Gimnyeong Maze Park is said to sit near the beach, and it's frequently introduced as a light stop after time in the water. It's reported to offer the particular fun of finding your way through a maze, though exact operating hours and admission details can vary by when you visit, so it's worth checking on site or through the latest notices. A bit further on, Manjanggul Cave is also said to be close by, and many visitors touring the Gimnyeong area reportedly bundle the beach, the maze park, and the cave into a single day's route. Manjanggul is said to be known for the cool temperature typical of lava tubes, which is often mentioned as a welcome break from summer heat. That said, the sections open to visitors and the cave's operating hours can also shift with the season and how the site is managed, so this piece introduces it only as a route commonly paired with Gimnyeong.
