The Boulder County Fair is the oldest fair in Colorado celebrating its 150th year. The Fair is a non-profit that rents the grounds and facilities from Boulder County who in turn is our main sponsor supporting the 4-H and open events during Fair.
The Fair is a "Free" fair meaning no charge for parking or gate admission so please come as often as you would like. We want you to enjoy the "free" musical entertainment and many of the other activities on the grounds. Don't forget to purchase a ticket to any one of our motorized sports, rodeos or special events because that is one of the ways we can continue each year. We hope you also support our on-site vendors or the many sponsors who help to keep the Fair.
