The Western Idaho Fair is a longstanding summer tradition in the Treasure Valley, bringing together families, exhibitors, performers, local organisations and visitors for a large regional fair. Its programme combines entertainment, exhibits, competitions and community traditions, offering activities for visitors of different ages and interests. The fair’s 2027 format is expanding to cover three weekends, giving visitors more flexibility to attend.

The organisers have also announced that the fair will be closed on Mondays and Tuesdays under the new format. Entertainment and activities are expected to be announced through the official fair programme as the event approaches. The fair provides a platform for local exhibitors and community groups while continuing its role as a major annual gathering for the region.
