Disney California Adventure Park, commonly referred to as California Adventure or by its acronym DCA, is a theme park located at the Disneyland Resort in Anaheim, California. It is owned and operated by The Walt Disney Company through its Parks, Experiences and Products division. The 72-acre (29 ha) park is themed after Disney's interpretation of California, which is manifested through the use of various Disney, Pixar and Marvel Studios properties. The park opened on February 8, 2001 as Disney's California Adventure Park and is the second of two theme parks built at the Disneyland Resort complex, after Disneyland Park. The concept of a theme park dedicated to California arose from a meeting of Disney executives in 1995, following the cancellation of WestCOT, a planned West Coast version of Walt Disney World's utopian EPCOT Center. Construction of the park began in June 1998 and was completed by early 2001. Disney initially projected high attendance rates at the new park; a series of preview openings held in January 2001 led to negative reviews, however, and after the park officially opened to the public on February 8, 2001, the company's attendance projections were never met. Disney spent the next several years incrementally adding new rides, shows, and attractions, and implementing other promotions aimed at boosting attendance. In 2007, Disney announced a major overhaul of the park consisting of new expansion as well as re-construction of existing areas of the park. Construction lasted for five years and was completed in stages, culminating with the opening of Buena Vista Street and Cars Land along with the re-dedication of the park in June 2012. The most recent addition to the park was the completion of Avengers Campus when the Disneyland Resort reopened in mid-2021, after being closed for over a year due to the COVID-19 pandemic. According to the Themed Entertainment Association, the park hosted approximately 9.9 million guests in 2018, making it the 12th-most visited theme park in the world that year.
