Port Adventura, Tarragona, Spain

The only rollercoaster in Europe with eight inversions

With loops and turns bearing titles such as "cobra roll" and "diving loop," this rollercoaster whips riders around with all the fury and fight of an angry dragon. But for all of its action, Dragon Khan is a smooth ride that prompts many to laud creators Bolliger and Mabillard for the finesse and sleekness of its twists and turns.
