12 of the World's Greatest Roller Coasters


Dueling Dragons

Located at Islands of Adventure in Orlando, Florida, Dueling Dragons is the world's first high-speed, dueling inverted roller coaster; inverted means that the cars travel under the track rather than on top of it. Dueling Dragons is actually two roller coasters, one representing fire and the other ice. Each has several throat-gulping inversions, including corkscrews, vertical loops, and a cobra roll. Top speed is 55 miles per hour with a maximum height of 125 feet. Riders on each track zoom within inches of each other in three near-miss experiences that elicit plenty of screaming.
