What makes it special
Saekki Islet off Munseom is one of Jeju's most celebrated dive destinations, adored by beginners and experienced divers alike. Gentle rocky slopes descend from 10 to 25 meters, densely blanketed with dazzling pink and purple soft corals (Dendronephthya).
Thousands of native damselfish and sweepers form shimmering clouds over the coral gardens. When sunlight filters through the clear water, the vivid colors create an unforgettable underwater spectacle that epitomizes Jeju diving.
