Hawaii exclusive design pin. Kona is a moku or district on the Big Island of Hawaiʻi in the State of Hawaii, known for its Kona coffee and the location of the Ironman World Championship Triathlon. In the current system of administration of Hawaiʻi County, the moku of Kona is divided into North Kona District (Kona ‘Akau) and South Kona District (Kona Hema). The term "Kona" is sometimes used inaccurately to refer to its largest town, Kailua-Kona.
