Join the tradition at Cox Farms, the largest seasonal festival in the D.C. area! Explore through the adventure trails, ride the many (and huge!) slides, listen to live music, participate in fun farm chores, enjoy toddler time at the Kiddie Zone and so much more. Since the farm was founded in 1972, it has been the most popular fall destination for families in the area and is a place the whole family is sure to love!
