When the sun goes down, Boo at the Zoo comes alive with three nights of Halloween fun for the whole family. Dress up for trick-or-treating and a costume contest, then enjoy a DJ and dance floor, animal encounters, bounce houses and inflatable slides, train rides, a photo booth, rock wall, kids’ hay maze, spooky stories and s’mores by the campfire, and more!
