Planning Your Visit
Duncan is in the upper Gila River valley near the New Mexico border — Greenlee County is dominated by the Morenci copper mine, one of the largest open-pit copper mines in North America.
A Closer Look
Duncan's Greenlee County Fair is a four-day mid-September celebration in Arizona's smallest county by population, serving the copper mining and ranching communities of the upper Gila River canyon.
Fair Highlights
Expect livestock judging, 4-H competitions, rodeo events, carnival rides, and the close-knit community spirit of one of Arizona's most remote and genuinely frontier counties.
