Alameda County Fairgrounds

Alameda County Fairgrounds is a 267-acre event destination in Pleasanton, California, positioned at the I-680/I-580 interchange in the heart of the East Bay. The grounds combine expansive open lawns, mature trees, and a collection of purpose-built event buildings that accommodate everything from intimate gatherings to large-scale festivals, trade shows, corporate events, and weddings. The venue offers more than a dozen distinct indoor and outdoor spaces spanning a wide range of guest counts. Smaller spaces like the Sky Lounge and The Farmhouse seat 125 to 175 guests in contemporary, fully equipped settings, while the four Court of Four Seasons buildings — Winter, Spring, Summer, and Autumn — each accommodate several hundred guests for banquets, meetings, and social events. For large-format programming, Building A delivers 32,500 square feet of column-free floor space, a banquet capacity of 1,520 and a reception capacity of 2,900, and the open-air Amphitheater welcomes up to 3,000 guests for concerts, graduations, and outdoor performances. In-house catering and beverage service is available across the property, and the fairgrounds also features a 9-hole golf center, full-service RV park, and equestrian center.
