A volcanic Korean island of haenyeo coasts: Munseom, Beomseom, Udo, and a 2016 UNESCO listing for women divers who work on one breath. Jeju is a volcanic island south of the Korean Peninsula, listed as a UNESCO World Heritage volcanic site in 2007.
Wow factor is high for a temperate-to-subtropical island, a step below the equatorial places in this atlas. Seasonality is high: winter winds and a short warm-water window. Accessibility is middling-high: domestic flights and a few shore snorkels, plus boat dives that wait on swell. Risk is moderate: current, cold, and boat traffic, not wreck-penetration scores.

This chapter is a place atlas, not a haenyeo costume, not a certifying agency, and not a live briefing. Jeju marine park rules, the day's wind and a working dive-ground override any sentence here. A small island east of Jeju (the name means cow) with beaches and shallows used for snorkelling, including Hagosudong-type sand. A ferry, not a liveaboard.
Jeju women who harvest on breath-hold, a living work culture listed by UNESCO in 2016. Tourists should not copy the work or treat a dive-ground as a playground. See freediving and Jeju's culture chapter.
