The Wildlife World Zoo & Aquarium traces its roots back to the early 1970s when Mickey Ollson started a breeding area for birds. Even though it was not open to the public initially, the zoo expanded in its first decade and opened to the public in 1984. The Zoo now covers 200 acres just to the west of Phoenix, Arizona. A large aquarium was added in 2008. In 2016, the Adventureland section opened. It contains three rides and one roller coaster.
