Sidewinder is a steel roller coaster located at Elitch Gardens in Denver, Colorado.

The train is launched down a hill, goes into the loop, then ascends a slope opposite of the station with a braking section.

Before being operated at Elitch Gardens this roller coaster was at the Magic Springs & Crystal Falls amusement park as the Roaring Tornado.

It is one of only three Arrow Dynamics launched loop coasters to be operating around the world, the others being Diamond Back at Frontier City, and the Revolution at Blackpool Pleasure Beach.

The ride has received new paint for the 2010 season, and is now more of a lime green than the darker shade it has been since being repainted from its original white.
