Corkscrew, Steel roller coaster in Athol, Idaho
Corkscrew is a steel roller coaster in Athol, Idaho that takes riders through two complete inversions along its steel track of loops and turns. The ride features multiple elements including camelbacks and sharp curves that flow throughout the entire circuit.
The coaster debuted in 1975 at Knott's Berry Farm in California, marking a turning point in steel roller coaster design. It was relocated to its present location in Idaho after being purchased and moved to Silverwood Theme Park.
The roller coaster design by Ron Toomer revolutionized theme park engineering as the first modern steel coaster to turn riders upside down.
Visitors experience a steep climb of about 72 feet followed by rapid descents and multiple turning points throughout the ride. Those sensitive to inversions should prepare themselves mentally, as the ride delivers intense moments from start to finish.
This was the first steel model of its kind to feature modern inversion design, inspiring ten identical copies built between 1975 and 1979. Those replicas spread across the globe and established new manufacturing standards for the coaster industry.
