Insane (Gröna Lund)

Insane is a roller coaster at Gröna Lund in Stockholm. Insane is an Intamin Zac-Spin roller coaster. It opened in 2009. The train cars contain 4 seats with 2 on each side. When navigating the course, the trains are free to spin and flip. In 2011, a similar roller coaster, Green Lantern: First Flight, opened at Six Flags Magic Mountain.

After the deadly incident on Inferno at Terra Mítica in Benidorm, Spain on 7 July 2014, and because the two rides share several similarities, Gröna Lund had ceased running Insane for several days before reopening the coaster.
