Gimnyeong Seongsegihaebyeon Beach

The clear waters that are highlighted with cobalt-blue and the clean white sand of Gimnyeong Seongsegihaebyeon Beach steal the hearts of visitors every year. The beach is also popular with fishermen, who enjoy rope fishing from the rocks. This area is known to be good for catching striped beakfish and spotty belly greenlings. Not far from the beach is Manjanggul Cave, which offers a welcome escape from the daytime heat. Official location: 237 Gujwahaean-ro, Jeju-si, Jeju-do. Parking: Available. Information contact: +82-64-728-3988. Visit Jeju explains that the beach formed where sand accumulated over a broad, flat layer of volcanic rock. 'Gimnyeong' refers to the level-looking shape seen from above, while 'Seongsegi' recalls a small defensive fortress. The official page also places the beach on a UNESCO Global Geopark trail linking village history with nearby volcanic features and lists a campground, parking, restrooms, changing rooms, and showers.
