Roller coaster enthusiasts cheered as this iconic dueling wood coaster returned as the new Twisted Colossus, one of the longest and most innovative I-Box coasters in the world! Still in its landmark location along the perimeter of Six Flags Magic Mountain, Twisted Colossus remains the racing coaster monument most recognizable to millions of people who pass by the park each year. Twisted Colossus is RMC’s only Mobius loop coaster, where a train completes both ride cycles before returning to the station.
