If you've not been to Disneyland for a while, you'll hardly know the place.
Disneyland Park, the original Disney theme park and the only one that Walt Disney saw completed in his lifetime. Much more than the Magic Kingdom at Walt Disney World, Disneyland Park embodies the quiet, charming spirit of nostalgia that so characterized Walt himself. The park is vast yet intimate, steeped in the tradition of its creator yet continually changing.
Disneyland Park is a collection of adventures, rides, and shows symbolized by the Disney characters and Sleeping Beauty Castle. It's divided into eight subareas, or lands, arranged around a central hub. First encountered is Main Street, U.S.A., which connects the Disneyland entrance with the central hub. Moving clockwise around the hub, the other lands are Adventureland, New Orleans Square, Frontierland, Fantasyland, and Tomorrowland. Two major lands, Critter Country and New Orleans Square, are accessible via Adventureland and Frontierland but do not connect directly with the central hub. Another land, Mickey's Toontown, connects to Fantasyland.
The second and newest park, Disney California Adventure (or DCA to the initiated), celebrated its grand opening on February 8, 2001. DCA is an oddly shaped park built around a lagoon on one side and the Grand Californian Hotel on the other, with one of Disney’s trademark mountains, Grizzly Peak, plopped down in the middle. Buena Vista Street, an entranceway evoking 1920s Los Angeles, leads to seven “lands.” Inside the front gate and to the left is Hollywood Land (formerly Hollywood Pictures Backlot), a diminutive version of the Disney’s Hollywood Studios theme park at Walt Disney World. Then there are Condor Flats, Grizzly Peak, and Pacific Wharf, a trio of mini-lands (originally known collectively as Golden State) celebrating California’s industry, cuisine, and natural resources. Next is a bug’s land, with characters and attractions based on the Disney-Pixar film a bug’s life. Cars Land is dedicated to the desert town of Radiator Springs from Disney-Pixar’s Cars. Finally, Paradise Pier recalls the grand old seaside amusement parks of the early 20th century.
