Solano County Fairgrounds and Event Center is a premier venue in Vallejo, California, hosting the iconic Solano County Fair each summer. With versatile indoor and outdoor spaces, the fairgrounds accommodate a wide range of events—from community festivals to corporate gatherings, weddings, and concerts. The venue features modern amenities, dedicated event support, and easy access to major highways. Visitors appreciate the large open spaces, ample parking, and safety and security provided by the staff. The fairgrounds host regular events like dog shows, with RV and overnight parking available. While the facilities and restrooms may be dated, they are still functional and clean. The main hall and McCormick hall are spacious, with high ceilings to accommodate vendors and displays. However, the McCormick hall can get stuffy during the summer. The fair itself has seen a decline in attendance over the years, but still offers a family-friendly experience with food, music, and opportunities to interact with farm animals. Whether attending the annual fair or hosting a private event, the Solano County Fairgrounds offers a memorable experience in the heart of Solano County.
We had a blast watching the Roller Derby teams do their thing! The entrance was confusing though...the main gates were locked with no signage pointing us to the Sage St gate. It was our first time going to we almost turned around and went home.

I loved taking my grandkids to the fair at this location. It is a smaller venue with visible security, and there is something for everyone.

It was nice. Clearly, it was much smaller than the state fair, but nice. However, the exposition buildings are in much need of paint, repair, and upkeep. It was kind of embarrassing as these facilities represent our community.
