Rock Creek Farm is one of the largest and most amazing Halloween attractions in northern Colorado and admission is always free. We really do have over 100 acres of U-Pick-Em pumpkin fields for you and your entire family to explore. Pumpkins aren't where the fun stops, try our hay bale maze or get lost in the winding paths of over six miles of Corn Mazes. We offer a variety of activities, caramel apples, and Halloween fun!
