About Butte County Fair
The Butte County Fair in Arco celebrates the first city in the world to be lit by nuclear power — Arco's claim to fame is being illuminated by electricity generated at the Idaho National Reactor Testing Station in 1955, and the county's Lost River Range's remarkable landscapes, cattle ranching in the upper Lost River valley, and the extraordinary Craters of the Moon lava fields define a county of unique geological and scientific significance.
What to Expect
Expect a small fair with livestock exhibits, 4-H competitions, local food vendors, and the authentic spirit of a remote Idaho high desert ranching county.
Visitor Tips
Craters of the Moon National Monument preserves the most recent volcanic landscape in the continental United States — an eerie world of lava flows, cinder cones, and lava tube caves. Arco's atomic energy heritage is celebrated at the EBR-I Atomic Museum, where the original experimental reactor is preserved.
