From Wikipedia, the free encyclopedia
Sierra Sidewinder is a steel spinning roller coaster located in the Camp Snoopy section of Knott's Berry Farm. It is the first ever roller coaster to feature multiple free spinning cars on a train, rather than several individual spinning cars. The only other spinning train coaster is Euro-Mir at Europa-Park in Germany, however the spinning of the trains is controlled throughout the ride. Sierra Sidewinder features trains with four cars with two rows each, seating two per row back-to-back. It is also one of the first roller coasters to feature on-ride video recordings, as opposed to the traditional still on-ride photograph.
