The first Arapahoe County Fair was held in 1906, along the banks of the South Platte River within present day Littleton. The Fair is one of Arapahoe County's longest-standing community traditions. The County Fair has travelled to various locations including Deer Trail, Byers, Englewood and Littleton. The current location of the Arapahoe County Fairgrounds was commemorated in July of 2006, marking the 100th anniversary of the Fair.

The Fair continues to showcase the County's agricultural and western heritage through 4-H programming, traditional agricultural activities and entertainment. For the price of your admission you can also enjoy carnival rides, daily motor sports, canine entertainment, a petting farm and numerous other activities.
