Disneyland is a theme park located in Anaheim, California, USA. It opened on July 17, 1955. The park is owned and operated by The Walt Disney Company. The park consists of various areas with separate themes: an early 20th century Midwest town, jungle adventures, the western frontier, fantasy, and the future. These areas are named, respectively, Main Street USA, Adventureland, Frontierland, Fantasyland, and Tomorrowland. Three additional areas were added to these original park areas later: New Orleans Square, Mickey's Toontown, and Critter Country. An elevated berm supports a three-foot (narrow) gauge railroad which circumnavigates the park. Disneyland features rides and attractions designed to appeal to all ages.
The park has been visited by more than 515 million guests since it opened to the public, including presidents, royalty, and other heads of state. Since 1998 Disneyland has been officially renamed Disneyland Park in order to distinguish it from the larger Disneyland Resort complex of which it is a part. In February 2001, Disney opened an adjoining yet separate amusement park called Disney's California Adventure.
