California Adventure is Disney's newest theme park, located across from the entrance to Disneyland. The close proximity of the two parks makes it very easy for park hopping if you have a park hopper passport
Upon entering California Adventure you will be in the Sunshine Plaza, with sun sculpture and waterfall.
From here you can head to the Hollywood Pictures Backlot. In the Backlot is The Muppets 3D show, which is fun for all ages. I have seen it a number of times and keep going back. The Hyperion Theatre has a show "Steps in Time" about a teenager and his fairy godmother. The singing and dancing were very good but the voice of the fairy god mother kind of grated on my nerves, but otherwise it was okay.
My favorite part of this area was the Disney Animation Studio, where you learn about animation and also can take a computer quiz to find out which character you are most like. There is also an opportunity to sing/act a part in a film. I really like this area, but the line ups were always very long. With only about 6 machines, expect a long wait even when the park isn't too busy. The worst attraction in this area - Superstar Limo. Some people getting off of this ride really seemed to enjoy it but we found it dull, it is a car ride through Hollywood with cardboard cutouts of the streets of Hollywood.
The Golden State was a favorite area, with Soaring over California and the Grizzly River Rapids. The rapids were a lot of fun. You are warned you will get wet, but you will probably get soaked. Go late in the day so you aren't walking around in wet clothes all day. The Bugs Life 3D film was also a lot of fun, with surprises.
At the back of the park is Paradise Pier. The rides here are mainly for those with a strong stomach. California Screamin', a high speed roller coaster; Mailboomer, a high speed launch; and the Sun Wheel, a Ferris wheel with cars in the middle that slide back and forth.
Each area also has theme restaurants, snack bars and shops .
There is a daily parade, Eureka, which was very upbeat and colorful. It is a tribute to the different areas of California. For summer they are also adding the Electric Light Parade.
Overall I liked California Adventure, but did not feel it was worth the same admission as Disneyland. The park is not as large as Disneyland, there are not as many rides, and there were limited rides for families with children.
Perhaps in a few years with some expansion there will be a broadened range of rides and attractions.
On the plus side, the characters are very accessible in the Sunshine Plaza area, without the long waits that Disneyland has.
