Disney California Adventure Park, commonly referred to as Disney California Adventure, California Adventure, or DCA, is a theme park located in Anaheim, California. It is owned and operated by The Walt Disney Company through its Parks, Experiences and Consumer Products division. The 72-acre (29 ha) park is themed after the history and culture of California, which celebrates the fun and adventure of the state through the use of various Disney, Pixar, and Marvel properties. The park opened in 2001 as Disney's California Adventure Park, and it 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 the WestCOT project. Construction of the park began in 1998 and was completed by early 2001. Disney initially projected high attendance rates at the new park, however, a series of preview openings held in January 2001 led to negative reviews, 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 expansion of the park as well as a major overhaul of a significant portion of the park. Construction lasted for five years and was completed in stages, culminating with the opening of Buena Vista Street and Cars Land in June 2012.
According to the Themed Entertainment Association, the park hosted approximately 9.4 million guests in 2015, making it the 11th-most visited theme park in the world that year.
