A ark ride or darkride is an indoor amusement ride where riders in guided vehicles travel through specially-lit scenes that typically contain animation, sounds, music, and other special effects. The name can be misleading, since a dark ride does not have to be dark. (Disney's It's a Small World is an example of a brightly-lit dark ride.) Nevertheless, most use special lighting to achieve theatrical effects. Selective use of darkness is advantageous because it helps hide the mechanisms of the ride and because it can increase the visual drama of the experience.
