Gimnyeong Seongsegi Beach

Gimnyeong Seongsegi Beach (김녕성세기해변; map) lies Jeju Island’s eastern shore, featuring pristine white sands and shallow emerald waters.

Formed over vast lava rock formations, this tranquil beach is favored by locals and offers a serene alternative to busier destinations like Hamdeok or Jungmun Beach. It is also a key highlight on the Jeju Fantasy Bike Path, making it a perfect stop for cyclists.

Geological Significance

Gimnyeong Seongsegi Beach sits atop large lava rock slabs, overlaid by fine white sand. This unique topography gives Gimnyeong Seongsegi its distinct aesthetic. Its formation aligns with Jeju’s volcanic heritage, and the surrounding area is part of a UNESCO Global Geopark.

Nearby, visitors can explore the Gimnyeong Geotrail (김녕 거트레일), which integrates the island’s geological features with local history and culture.

Activities and Attractions

With shallow waters and a calm current, Gimnyeong Seongsegi Beach is great for families with children. The soft sands and clear water make it a favorite spot for wading and beachcombing. Lifeguards and safety measures during peak season (July to August) ensure a safe experience.

Fishermen frequent the rocky shores for striped beakfish and spotty belly greenlings, using traditional rope fishing methods. Snorkeling and diving enthusiasts are drawn to the beach’s crystalline waters and marine biodiversity.

A short distance from the beach, visitors can cool off in Manjang Cave, Yongcheon Cave, or Dangcheomul Cave. These lava tubes maintain a steady temperature below 20°C year-round, making it a natural retreat from the summer heat.
