Dig up your zombies and grab your ghouls! Show off your boo-tiful costumes at Reid Park Zoo for a delightful, not too frightful, family friendly evening at Boo at the Zoo, presented by One AZ Federal Credit Union. You’ll have an enchanting time with the whole family at this Tucson Halloween tradition. Proceeds benefit Zoo animal care, operations, and education programs. Timed entry only: To make sure everyone has enough room to spread their bat wings, tickets to Boo at the Zoo will be sold with entry times this year and must be purchased in advance.
