The free day is offered as a thank you to Tacoma voters, who in 1999 approved a $35 million bond issue to pay for Zoo improvements. The money has funded several new additions to the zoo over the past decade, including Kids’ Zone and Animal Avenue, the Asian Forest Sanctuary, Wild Wonders Outdoor Theater, animal hospital, new front gate, education center, gift shop and café. Proof of Tacoma residency is required.
Adults 18+ are required to provide proof of residency at a Tacoma address (not a P.O. box). If your photo ID does not have a physical Tacoma address, you will be required to provide an alternative method of documentation, such as a photo ID with a utility bill (or other legal document that lists a Tacoma address) that matches the name on the photo ID. Each adult living at that address must provide an alternative method of proof of residency if their ID does not have a Tacoma address. Children age 17 and younger do not require proof of residence.
