Founded in 1929, the Lake County Fair Association is a 501(c) (3) non-profit organization that manages year-round operations of the Lake County Fairgrounds and Event Center, a multi-purpose exposition, conference, festival and special event venue. Located on 160 acres in Grayslake, Illinois and featuring the largest Expo Hall between Milwaukee and Chicago, the Lake County Fairgrounds and Event Center hosts thousands of visitors every year. Our events -- which include the annual Lake County Fair, in addition to RV shows, boat shows, car shows, monthly antiques and collectibles shows, fun runs, corporate, social and fundraising events -- all contribute to the economic vitality and growth of Lake County. Each summer, the iconic Lake County Fair celebrates our agricultural traditions in a family-friendly community gathering.
