Boo at the Zoo is a fun family event held every October 31st. 2021 is extra special since Boo falls on a Sunday! This year gates will open for Boo at 5:00 pm for families with children 6 and under and at 6pm for all ages. Last admission will be at 8:30 pm. Come in costume and trick-or-treat at different stations around the Sanctuary with your favorite animals. Bring a flashlight and see all the nocturnal residents and don’t forget to visit the new Boo Zone!
