The story of Diamondback
Kings Island announced Diamondback on August 6, 2008, presenting a 5,282-foot steel hyper coaster for the Rivertown section of the park. At $22 million, it was described then as the largest investment in the park’s thirty-six-year history. fox19.com
Bolliger & Mabillard of Monthey, Switzerland, supplied the ride, giving Kings Island its first coaster from that firm. The design brought a 230-foot lift, a 215-foot first descent, and a splashdown finale that made the old waterside setting part of the spectacle. bolliger-mabillard.com· sixflags.com
Diamondback opened on April 18, 2009. By July 20 of that same summer, the new coaster had carried its one millionth rider, a swift public welcome for the great red run over Rivertown. newsplusnotes.blogspot.com
The ride has remained one of Kings Island’s principal steel coasters, still operating with its 80 mph course and splashdown finish. In 2022, an Indiana visitor became Diamondback’s twenty millionth rider. sixflags.com· wrtv.com
