Blackfoot is home to the Eastern Idaho State Fair, which is Idaho's largest fair and the premier agricultural celebration of the upper Snake River Plain, held each September in a region that grows more potatoes than any other county in the United States. Since its 1902 founding, it's endured as a century-plus Idaho agricultural tradition. Blackfoot proudly calls itself the Potato Capital of the World, and the fair honors that legacy while delivering a full-scale state-fair experience with top-tier entertainment.

Twin Falls's Twin Falls County Fair celebrates the Magic Valley's agricultural heart — the Snake River canyon's Shoshone Falls (higher than Niagara), Evel Knievel's attempted Snake River Canyon jump, and the sprawling irrigated farms that produce potatoes, dairy, trout, and hops define a county that is one of Idaho's most productive agricultural regions.

In Coeur d'Alene, the Kootenai County Fair celebrates northern Idaho's most rapidly growing county — the "Lake City" of Coeur d'Alene has become one of the Pacific Northwest's most desirable destinations for its extraordinary lake, mountain scenery, and recreation economy, and the county's agricultural communities, timber heritage, and Silver Valley mining legacy come together at a major Northern Idaho fair. First held in 1922, it's carried on as an Idaho agricultural tradition for well over a hundred years.
