Jukdo
Jukdo
The premier dive area around Jukdo, the largest of Ulleungdo's satellite islets (about 4.8 km northeast of Jeodong Port). More than ten sites have been developed, from gentle slopes to 30–50 m walls, famed for its sea fan and black coral colonies and some of Korea's best visibility.
Walls and kelp beds
across a dozen sites
Around Jukdo, about 4.8 km northeast of Jeodong Port, more than ten sites such as No. 1–4 have been developed. Across varied terrain — gentle slopes (No. 1 and 4), a semi-cave and kelp beds (No. 2), coral and anemone colonies (No. 3), and 30–50 m walls — sea fan and black coral (baeksong) colonies and large migratory fish gather.
