As if the usual dinosaur skeletons and other bones at this iconic museum weren't haunting enough, the halls of the American Museum of Natural History sport chilling decor for its annual Halloween party. Kids dressed in ghoulish garb can trick-or-treat, make arts and crafts and mingle with cartoon characters and stilt walkers. Special live shows include Gazillion Bubble Show appearance, the Big Apple Circus and more. Reservations recommended. All ages.
