Participate in a special scavenger hunt, take a wagon ride on the 12-acre field, and create a boo-tiful Halloween craft during this unforgettable evening. Come and see wool carding, spinning, and fish net making in the historic area before greeting “Martha Washington” on the piazza of the mansion. In order to burn off all the extra excitement, try 18th-century dancing in the upper garden. Historic chocolate-making demonstrations and chocolate tastings will take place. A children’s costume parade around the mansion will begin at 5 p.m. and prizes will be awarded for most fang-tastic “George” and “Martha” costumes! Trick-or-Treating at Mount Vernon takes place rain or shine.
