Castle Park, formerly Castle Amusement Park, is a 25-acre amusement park and family amusement center located in Riverside, California. The park utilizes a medieval "castle" theme and includes attractions such as a miniature golf course, arcade, and 27 amusement rides including three roller coasters such as "Merlin's Revenge", a junior rollercoaster, "Screamin' Demon" a spinning Wild Mouse rollercoaster, and "Little Dipper", a children's rollercoaster. The main "castle" themed building, houses the arcade as well as its only dark ride; "Ghost Blasters", an interactive attraction, designed by Sally Corporation, which can also be found at other amusement parks throughout North America. The park was designed, built and operated by Bud Hurlbut, who designed several rides at Knott's Berry Farm. Castle Park is currently owned and operated by Palace Entertainment.
The park opened in 1976 as a Family entertainment center, featuring a castle themed building housing a large two level video game arcade, and an outdoor miniature golf course. In 1985, the park expanded by adding an adjacent amusement ride area, featuring a collection of classic rides such as a Dentzel carousel built in 1905, a miniature railroad, and a log flume ride, thus becoming a legitimate amusement park.
In 1999, the park opened Ghost Blasters, an interactive dark ride designed by Sally Corporation. The ride feature's laser guns which riders use to shoot at targets to accumulate points. The attraction is the park's first and only dark ride, and occupies the entire second floor of the former arcade area inside the main castle building, reducing the arcade to only the first floor.
In 2008, the park opened "Dragon Flyer", a spinning flat ride, and "Sceamin' Demon", a spinning wild mouse rollercoaster.
