Come to Woodstock, Illinois to enjoy family friendly events hosted by McHenry County Fair Association. We reopened the fairgrounds in 1949 and have been entertaining the community ever since. The County Fair takes place for 5 days every year in the first week of August. If you have an event you would like to hold at our facilities, contact the office for rental information. We have four exhibition buildings, a pavilion, and four animal barns available.
