Diamondback is a steel hyper roller coaster located at Kings Island in Mason, Ohio, USA. At a cost of $22 million, it was the park's largest investment until the construction of Orion in 2020. Built by Bolliger & Mabillard, Diamondback was the second roller coaster to use staggered seating with the first one being Behemoth at Canada's Wonderland, which opened in 2008.


Diamondback was unveiled in August 2008.[1] The roller coaster was topped out on January 26, 2009.[2] In February 2009, the ride began testing.[3] The attraction opened on April 18, 2009.[4]

The trains received new seat belts during the 2014 season.[5]

For the 2018 season, the original red seats were replaced with new black ones.[6]



The ride is an out and back featuring ten hills. Diamondback has a 74-degree drop at a height of 215 feet and a splashdown at the end of its course, before the final brake run.

Color scheme

Diamondback has red track with yellow and tan supports.


3 trains with 8 cars per train. In each car, riders are arranged 4 across in a single row, for a total of 32 riders per train. Riders are held in by lap bars.

Diamondback was given its name from the venomous snake, the Diamondback. The ride is also themed around the snake. Interestingly, the paint colors are not similar to the Crtalus Atrox.
