Boo at the Zoo returns to the San Francisco Zoo for some trick-or-treating fun with the animals! Come dressed up in you Halloween costume and enjoy the day roaming the Zoo for tasty treats to take home. Don't miss out on spectacular magic shows, take-home crafts and the amazing pumpking "chomp 'n stomp" where the animals get their own Halloween goodies!

Activities are free with paid Zoo admission and no registration is required for this event. The Zoo requests that trick-or-treaters not wear rubber masks as they may frighten the animals.
