Boo at the Zoo

Please note: This event has already occurred.
Spooking the animals is usually frowned upon at the National Zoo, but for a few days each October, that changes slightly. That's when scores of children don their Halloween costumes and take to trick-or-treating there, with treat stations set up at points throughout the park. Also on tap are plenty of Halloween-themed animal events. Best for ages 4 to 12.
