Disney's California Adventure Park is a theme park in Anaheim, California, adjacent to Disneyland Park and part of the larger Disneyland Resort. It opened on February 8, 2001. The park is owned and operated by The Walt Disney Company.
This 55-acre (220,000 m2) theme park was constructed as part of a major expansion that transformed the Disneyland area and its hotels into the Disneyland Resort and consists of five areas: Sunshine Plaza, Hollywood Pictures Backlot, The Golden State, A Bug's Land and Paradise Pier. Each area is meant to resemble various aspects of California, its culture, landmarks and history. In 1991, Disney announced the plan to build a second gate in Anaheim, WestCOT, a west coast iteration of Epcot, in place of the existing Disneyland main parking lot, but due to various reasons the project was canceled in 1995, which led to the idea of Disney's California Adventure (DCA), a park to celebrate and pay tribute to California, providing a similar experience to stepping inside a California postcard.
DCA was part of the plan to expand the one park property and convert it into a greater, multi-day vacation resort destination which would be able to appeal to a greater audience - similar to Walt Disney World resort.
