Vortex, Steel roller coaster in Rocky View County, Canada.

Vortex is a steel roller coaster in Rocky View County that completes two full loops around its track. The green and purple structure features sharp turns and drops along its path.

The coaster opened as Turn of the Century, painted an earth-tone brown to sit against the surrounding landscape. It was renamed Corkscrew in 1986. In the 2004 off-season the track and supports were repainted green and the train pink, and the ride became The Vortex, debuting for the 2005 season to mark Alberta's centennial. In the 2019 off-season Baynum Painting gave the track a green and purple scheme.

The name Vortex replaced Corkscrew in the 2004 off-season, when the ride was rebranded with the slogan "Fun From The Bottom Of Your Stomach"; the change debuted for the 2005 season and was made for Alberta's centennial. The pink train kept its colour through the 2019 repaint.

Visitors must be at least 48 inches (122 centimeters) tall to ride, with operations following Calaway Park's seasonal schedule. It's worth checking the opening times in advance since they vary by season.

The coaster runs two laps per ride instead of one, a decision made because its track is short for a coaster of its size. Riders therefore go through the corkscrew twice on every cycle.
