Freediving in South Korea
Including Munseom Island, Seopseom Island, and Ulleungdo Island. On the map.
The vibe
Breath-hold diving here is deeply tied to the historic coastal culture of free-diving women harvesting seafood by hand, giving the practice a profound local resonance. Summer and early autumn provide the calmest seas and tolerable water temperatures for extended sessions. It feels grassroots and tight-knit, blending traditional coastal life with modern independent practitioners.
