The Boulder County Fair returns for 2024!

The Boulder County Fair is the oldest fair in Colorado celebrating its 154th 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 are proud to host an event that celebrates our rich agricultural culture, traditions and community. At the Boulder County Fair, there is something for everyone.
