Point Defiance Zoo & Aquarium

Point Defiance Zoo & Aquarium (PDZA) is the only combined zoo and aquarium in the Pacific Northwest. The 29-acre zoological park was established in 1905, and attracts about 700,000 visitors a year. It is nationally accredited by the Association of Zoos & Aquariums (AZA), which ensures rigorously high standards of animal welfare, veterinary care, conservation, education and more.

The Zoo sits within 700-acre Point Defiance Park, offering spectacular views of Mount Rainier, the Olympic Mountains and Puget Sound. PDZA is operated by Metro Parks Tacoma, the oldest independent park district in Washington.

The Zoo Society fosters the relationship between Point Defiance Zoo & Aquarium and our community by raising funds and generating community support.

The Zoo/Trek Authority was established in 2001 to oversee disbursement of sales tax revenue to Point Defiance Zoo & Aquarium and Northwest Trek Wildlife Park. In 2000, Pierce County voters approved a one-tenth-of-a-cent increase in the local sales tax rate to support the Zoo, Northwest Trek and parks.

One-half of these new local revenues go to Point Defiance Zoo and Northwest Trek. The other half is divided among park systems throughout Pierce County.

The ZTA is composed of seven elected officials appointed by city and county councils as follows:

  • Pierce County Council: 3 members
  • Tacoma City Council: 2 members
  • Other Pierce County cities/towns: 2 members

The ZTA is charged with approving the biennial operating budgets for Point Defiance Zoo & Aquarium and Northwest Trek prior to final adoption by the Metro Parks Tacoma Board of Commissioners.
