Cox Farm is located in Centerville, very close to Herndon, and is considered to be one of the best family farms in the area. Kids usually have the most fun getting to see the alpacas, rabbits, chickens, goats, and other animals up close. There are several other attractions like the Castle Slide, the Dino Slide and the Barn Slide in addition to resting stops and restaurants.
One could easily spend an entire day on the farm, but if you're on a time crunch, you can get the main attractions done in a few hours. Adults often enjoy the Festival Market the most, where they can sample apples, cider, pumpkins, and other seasonal foods.
