A historic treat! Mount Vernon opens its doors for the first time to trick-or-treaters! Join the costumed cast of interpreters for a special opportunity to trick-or-treat in the historic area. A special scavenger hunt is available for our more adventurous guests. All trick-or-treaters are invited to join in the children’s costume parade around the Mansion at 6 p.m. Prizes will be awarded for the best “George” and “Martha” costumes! Participate in a Halloween craft activity in the greenhouse. Special trade demonstrations, like 18th-century wool spinning and laundry washing, will take place in the historic area. Listen to Halloween-themed stories in the straw bale amphitheater, enjoy colonial games and dancing demonstrations, and take a wagon ride. The Mansion and Donald W. Reynolds Museum will not be open for this event. Tickets are required for all adults and children to attend this event. The cost is $10 per adult and $5 per child. Doors open at 3:30 p.m. and close at 6 p.m. Tickets are available at 10 a.m. on August 8.
