Disneyland CA Adventure (DCA) is the second theme park built in Anaheim. It is located right across from the Disneyland Main Gates. It opened in 2001 and has improved a little each year since its opening.
This year a new thrill attraction is opening: the Tower of Terror. This attraction is already open in Disney World; however, I've never been on it.
DCA is inspired by the many features of the great Golden State of California. Different areas of the park are modeled after different areas or features of CA, the state. For example, Paradise Pier depicts a place like Santa Cruz Beach and Boardwalk complete with carnival style games and a roller coaster that is supposed to look like the old time white wooden roller coasters. Another area depicts Hollywood and here you can see a live show of Aladdin. It's like seeing a Broadway show in LA or SF. Then there's the animation studio where you can see how the animated movies come to life. You can visit the soundstage of Who Wants to Be a Millionaire? and play a mock game for prizes. There's an area that depicts CA's agriculture and this is where you can see the Bug's Life 3-D film. The park is really an amazing tribute to the state.
For a veteran Disneyland fan, it is hard to have the same feelings visiting this park. I have a long history of visiting Disneyland and you can feel that Disneyland has more of a special feel because it is the original park that Walt Disney envisioned. DCA earns a little more of my affection each time I visit and I know eventually it will start to have some of the same charm and character that Disneyland has.
If you're going to Anaheim for only a few days, get a park hopper pass and you will probably end up spending more time in Disneyland, but do take some time here in DCA and see some of its main attractions.
