The list below does not include several private facilities that aren’t open to the public, but how many other zoos am I missing? There are several nature centers with very small animal collections but are they worth visiting? Are there some natural history museums with significant animal collections that could qualify as a "zoo"? I already posted a comprehensive list of Texas zoos and ended up with around 50 but California has approximately 60 zoos. 60 California Zoos: Applegate Park Zoo (Merced) Aquarium of the Bay (San Francisco)* Aquarium of the Pacific (Long Beach)* Big Bear Alpine Zoo (Big Bear Lake) Birch Aquarium (San Diego)* Bolsa Chica Interpretative Center (Huntington Beach) Cabrillo Marine Aquarium (San Pedro)* California Academy of Sciences (San Francisco)* California Raptor Center (Davis) California Science Center (Los Angeles)* California Living Museum (Bakersfield) Charles Paddock Zoo (Atascadero)* CuriOdyssey (San Mateo)* Doheny State Beach Interpretative Center & Aquarium (Dana Point) Emerald Forest Bird Gardens (Fallbrook) Feline Conservation Center (Rosamond) Folsom City Zoo Sanctuary (Folsom) Forever Wild Exotic Animal Sanctuary (Phelan) Fresno Chaffee Zoo (Fresno)* Gibbon Conservation Center (Santa Clarita) Happy Hollow Park & Zoo (San Jose)* Lindsay Wildlife Museum (Walnut Creek) Lions Tigers & Bears: A Big Cat & Exotic Animal Rescue (Alpine) Living Desert Zoo (Palm Desert)* Los Angeles Zoo (Los Angeles)* Marine Mammal Care Center (San Pedro) Marine Mammal Center (Sausalito) Micke Grove Zoo (Lodi) Monterey Bay Aquarium (Monterey)* Monterey Zoo (Salinas) Morro Bay Aquarium (Morro Bay) Oakland Zoo (Oakland)* Ocean Institute (Dana Point) Ocean World (Crescent City) Orange County Zoo (Orange) Pacific Marine Mammal Center (Laguna Beach) Palo Alto Junior Museum & Zoo (Palo Alto) Project Survival’s Cat Haven (Dunlap) Roundhouse Marine Studies Lab & Aquarium (Manhattan Beach) Sacramento Zoo (Sacramento)* Safari West Wildlife Preserve (Sonoma County)* San Diego Zoo (San Diego)* San Diego Zoo Safari Park (Escondido)* San Francisco Zoo (San Francisco)* Santa Ana Zoo (Santa Ana)* Santa Barbara Zoo (Santa Barbara)* Santa Monica Pier Aquarium (Santa Monica) Sea Life Carlsbad (Carlsbad) SeaWorld San Diego (San Diego)* Sequoia Park Zoo (Eureka)* Serpentarium (Lodi) Seymour Marine Discovery Center (Santa Cruz) Shambala Preserve (Acton) Six Flags Discovery Kingdom (Vallejo) Star Eco Station: Exotic Wildlife Rescue Facility (Culver City) Tucker Wildlife Sanctuary (Orange County) Turtle Bay Exploration Park (Redding) Ty Warner Sea Center (Santa Barbara) Wildlife Learning Center (Sylmar) Wolf Mountain Sanctuary (Lucerne Valley) * 23 zoos in California are AZA-accredited.
