Gangneung Airport (K-18) — Gangneung, South Korea

Gangneung Airport, also known by its military designation K-18, is located near the city of Gangneung on South Korea's east coast in Gangwon Province. KAG has historically functioned as both a Republic of Korea Air Force base and a civilian airport, though commercial passenger service has been intermittent over the years, sometimes suspended and later reinstated depending on demand and competition from high-speed rail links to Seoul. Gangneung itself gained international attention as a coastal cluster host city for the 2018 PyeongChang Winter Olympics, boosting regional infrastructure and transport links. KAG's civilian terminal is comparatively small, reflecting its secondary role behind the dominant military function of the airfield. The surrounding area is known for beaches, coffee culture, and proximity to the Taebaek mountain range.
