Idaho Festivals, Trade Shows, Home and Garden Shows, Holiday Celebrations 2026–2027.

Idaho is where you’ll find the exact Center of the Universe: a manhole cover in Wallace says so! The Gem State also birthed television, houses the world’s densest population of nesting eagles, hawks and falcons, has the deepest gorge in America and a waterfall taller than Niagara. Celebrate the out-of-the-ordinary to the out-of-doors at 184 annual events. All the extraordinary details on Idaho’s Festivals, Art Shows, Music Festivals and Craft Shows are here, including three of the largest: Western Idaho Fair, Boise Art Museum's Art in the Park and Emmett Cherry Festival.
