Bring your little ghosts, superheroes and princesses to enjoy trick-or treating at merchant shops, a costume parade, mini-train rides, balloon/facepaint artists, surprise costumed characters, and so much more. Prizes will be given for best costume and best group/family costume. The event is FREE and open to the public!
