Use the orange "Other dates..." button above to pick your date for Boo at the Zoo!

It’ll be all treats and no tricks for your little pirates and princesses at this year’s Boo at the Zoo, the region’s most unique Halloween event. Boo at the Zoo is a fun way for families to trick-or-treat and enjoy Halloween festivities, and all of our candy is made with sustainable palm oil to help protect wild orangutans and other species.

Choose your tickets based on the date and time you’d like to attend. Your ticketed time is the earliest time you can enter the Zoo. From the ticketed time, you have a half-hour window to enter the Zoo (for example, if your ticket is for 5 p.m., you need to be in line to enter the Zoo by 5:30 p.m.). Once you’re inside, you are welcome to stay in the Zoo until the event ends at 8:30 p.m.

Support the Zoo’s efforts to reduce waste by bringing your own trick-or-treat bag from home.

For the safety of all guests, costume masks and costume weapons may not be worn by guests 12 years of age or older.  Masks worn by guests 11 years of age and younger must have openings that allow the eyes to be seen and that do not obstruct peripheral vision.  Balloons are not allowed inside the Zoo (even as part of a costume) for the safety of our animals and wild animals.
