We're thrilled to invite you to our Family Fun Fest, a celebration of the simple joys of farm life. This special event was created to share the experiences we grew up with on the farm—outdoor adventures, hands-on fun, and plenty of memories in the making.Kids (and kids at heart) will love exploring our giant covered straw pile, racing down slides—including our Slide Barn and the thrilling 50' racing slide in the woods—pedaling tractors, pushing carts, and swinging on tire swings. Families can wander through the corn maze, dig into the sandbox, play in our farm-style buildings, or relax on a classic wagon ride.
