X2 | Six Flags Magic Mountain, Valencia, CA
First opening in January of 2002 as X, this one at Six Flags Magic Mountain in Valencia, California was the world’s first 4th Dimension coaster. It closed down in December 2007 to be turned into X2, reopening about five months later with special effects that include a sound system and a pair of flamethrowers.
If you’ve never ridden a 4D coaster, then you need to find one and make it happen. The seats are designed in a way that allows them to rotate forward or backward 360-degrees in a controlled spin while extending off the track. Riders pass under the flamethrowers right before entering the second raven loop, with a half twist finishing off the ride as it enters the final brake run.
All in all, this one, which takes just over two minutes to complete, should be ridden after dark to get the full experience from the special effects.
