Twisted Colossus is a steel roller coaster located at Six Flags Magic Mountain in Valencia, California.

Colossus became well known after appearances in film and television, including the box-office hit National Lampoon's Vacation and the made-for-TV movie Kiss Meets the Phantom of the Park.

Rocky Mountain Construction renovated the ride converting its wooden track to steel, allowing for the addition of inversions and steep drops.

[2][3] A member of the design team traveled to Mexico City to study Montaña Rusa – the largest wooden roller coaster in the world at the time – in order to help plan for the project.

During the Halloween season, the coaster's web-like structure was accompanied by a giant black spider, and the height restriction became 54 inches (1,400 mm).

On August 29, 2013, Six Flags Magic Mountain announced that they would run Colossus backward for a limited time during the 2014 season.

[6] Its original configuration was noted for numerous and sustained air-time moments, which were eventually toned down or eliminated by reprofiling and/or braking.

After crossing under the blue track's zero-g roll, it then goes up a double up and turns left, where the train hits the final brake run.

This is different from a traditional Möbius Loop layout (such as Racer at Kennywood), which takes riders through only half of the ride's "complete" circuit before stopping and unloading at the other station.

Because of the unusual setup of a one-station Möbius Loop layout, to race, the operators on Twisted Colossus must properly time dispatches.

Colossus was nearing completion in May 1978 when it was used as a backdrop for fight scenes in the NBC TV movie Kiss Meets the Phantom of the Park.

[17][18] On July 7, 2022, an 8-year-old girl was wounded in the head when a mobile phone struck her while she was riding the roller coaster.

[19] Twisted Colossus ranked in the Amusement Today's Golden Ticket Awards for best new ride of 2015 with 13% of the vote, coming in third place.
