About Bonneville County Fair
The Bonneville County Fair in Idaho Falls celebrates the Snake River Plain's most significant regional center — Idaho Falls' nuclear energy heritage at the Idaho National Laboratory (where the first nuclear power plant generated electricity in 1951), the Snake River's volcanic basalt canyon, and the productive potato and grain farms of the upper Snake River valley define a city of national significance.
What to Expect
Expect livestock shows, 4-H and FFA competitions, potato and grain exhibits, carnival rides, live entertainment, local food vendors, and a well-organized fair drawing from the greater Idaho Falls metropolitan area.
Visitor Tips
Idaho Falls's waterfall on the Snake River and the beautifully landscaped River Walk define a city whose agricultural and nuclear energy economies coexist. The Museum of Idaho, the Idaho National Laboratory Visitor Center, and the Teton Valley's proximity to Grand Teton National Park make the county a major destination.
