The Oldest Fairs in Colorado

The Colorado State Fair in Pueblo is the premier state fair of Colorado, held annually since 1869 at the Colorado State Fairgrounds — one of the longest-running state fairs in the American West. Dating to 1869, it is one of Colorado's oldest and most enduring agricultural fair traditions. This 11-day event each late August through Labor Day draws hundreds of thousands of visitors from across the Rocky Mountain region to celebrate Colorado agriculture, culture, and western heritage.

The Douglas County Fair in Castle Rock celebrates one of America's fastest-growing counties — the "Agate Capitol of America" and growing Denver south suburban corridor contains some of Colorado's finest horse ranches and equestrian communities alongside the rapidly expanding suburban development between Denver and Colorado Springs. First held in 1892, it has been a Colorado agricultural tradition for over a century.

The Denver County Fair celebrates Colorado's state capital and largest city — Denver is the Mile High City where the Rocky Mountain Front rises dramatically from the Great Plains, and the county's urban agriculture movement, rooftop farms, community gardens, and thriving farm-to-table food culture connect the city to the rich agricultural heritage of the surrounding Colorado plains and mountains. Launched in 2011, the fair continues to expand its programming and attendance.
