OC Fair in Costa Mesa
The OC Fair takes over the Orange County Fairgrounds in Costa Mesa for 23 days each July and August, blending a working agricultural fair with a full-scale carnival. Visitors browse junior livestock and 4-H exhibits, floral and produce competitions, and craft displays while free concerts, monster truck shows, and a midway of rides and novelty food stands draw well over a million guests across the run.
It is a large public fair with a distinct Southern California visitor draw.
