Corkscrew is a roller coaster at Valleyfair in Shakopee, Minnesota featuring one vertical loop and two corkscrews. Built in 1980, Corkscrew was planned to reflect the design of its sister roller coaster Corkscrew at Cedar Point. It is notably one of the first roller coasters to feature a double corkscrew, as well as a vertical loop. The main differences that the Valleyfair model has is the addition of a finale helix and the omission of the camelback before the loop. Until the hypercoaster Wild Thing (the fifth highest and fastest roller coaster in the world at the time it opened in 1996), Corkscrew was the only outdoor all-steel roller coaster in Minnesota. Corkscrew is currently the only roller coaster at Valleyfair with inversions. The coaster's track was painted blue when it open in 1980 but was repainted orange and yellow in 2011.
