The Fair

Held annually in Mountain Home, the Elmore County Fair sits at the edge of the Snake River Plain, where high desert scrub meets irrigated farmland and the Sawtooth foothills rise to the north. It is one of Idaho's earlier summer fairs, drawing families from across a county shaped by both agriculture and the nearby Mountain Home Air Force Base.

What You'll Find There

Expect livestock shows, 4-H competitions, rodeo events, carnival rides, and local food vendors celebrating the county's ranching and farming heritage.

Local Tips

Mountain Home is a convenient stop on I-84 between Boise and Twin Falls — pair the fair with a drive up into the Sawtooth National Forest for a full Idaho summer experience.
