Haenyeo, or 'sea women,' free-dive in frigid waters using only goggles and nets. They harvest seafood sustainably, holding breath for 2+ minutes at depths of 10-20m. This 17th-century tradition earned UNESCO Intangible Heritage status in 2016[6][7].

Once 30,000 strong, numbers dwindled to 4,450 by 2025 due to harsh conditions and youth disinterest. Training academies now revive the craft, blending tradition with modern safety gear[10].

Witness dives at Hado-ri or join cultural shows. Their resilience inspires global admiration[11].
