The Mason County Fair, held at the Mason County Fair Grounds in Point Pleasant, is the largest county fair in West Virginia (in terms of attendance). It is held every year during the first week of August. The high attendance is due to the large number of animals that are shown and sold there. There are feeder calf, goat, hog, lamb and steer categories. Also, there is a horse show on the first day of the fair. There is a chicken and rabbit house where people can look at and buy those animals. Another reason for the high number of attendance is the entertainment.
