Harley Quinn Crazy Coaster was a short-lived steel single rail powered coaster located at Six Flags Discovery Kingdom in Vallejo, California, USA.


Harley Quinn Crazy Coaster was announced on August 31, 2017.[1]

The ride vehicle was revealed at IAAPA 2017.[2]

Vertical construction began in April 2018.[3]

The ride was originally intended to open on June 17, 2018, but was then delayed by a week to June 24, 2018. The ride did not open on this date either. Harley Quinn Crazy Coaster eventually opened on August 3, 2018.

Harley Quinn Crazy Coaster suffered constant downtime and was criticized for being rough and uncomfortable. Riders were also complaining about the noise coming from the attraction.[4]

In a Facebook comment, the park subtly announced the removal of Harley Quinn Crazy Coaster in 2021.[5][6]



The track formed an "∞" (infinity) shape with two stations at ground level. Ride traversed through repetitive Immelmanns and dive loops. Riders would fly by one another, both forwards and backwards. The train had ten cars and sixteen rows seating two riders each.

The ride was the first Skywarp installation from Skyline Attractions.
