Celebrating more than 40 years, Cox Farms in Centreville has one of the largest fall festivals in the area, with family-friendly attractions and activities including spooky hayrides, rope swings, giant slides, farm animals, a cornfield maze, Kiddie Zone and Foamhenge. Best of all, everyone loves the free apple cider and apples. The festival is open daily through Nov. 5 from 10 a.m. to 6 p.m., and open until 5 p.m. in November.
