30 000 Won Deogyusan National Park

Deogyusan was designated South Korea's ninth national park in 1975, protecting a massif in the Sobaek range whose highest peak, Hyangjeokbong, reaches 1,614 meters. This coin belongs to the Bank of Korea's ongoing national parks commemorative program, which has methodically worked through the country's protected areas since the series launched — each issue tied to a specific park rather than a thematic rotation, making gaps in the series geographically meaningful.
