Top 5 Most Extreme Rollercoasters

Kingda Ka: the world's tallest and fastest roller coaster

Arms down, head back and hold on. With only 28 seconds, the Kingda Ka may not be very long, but it's bound to leave you wide eyed and twitching. Located at Six Flags Great Adventure in New Jersey, USA, it's the tallest and fastest roller coaster in the world. The train is launched by a hydraulic launch mechanism to 128 miles per hour (206 km/h) in 3.5 seconds. At the end of the launch track, the train climbs the main top hat tower, reaching a height of 456 feet (139 meters)! At a cost of US$25 million, the Kingda Ka opened to the public on May 21, 2005, was closed several times for different technical problems and was also struck by lightning in early May 2009.

Dodonpa: the highest launch acceleration, 2.7 g

Steel Dragon 2000: the world's longest track length, 8,133ft

Built by Morgan Manufacturing, this gigacoaster at Nagashima Spa Land Amusement Park in Mie Prefecture, Japan, opened in 2000 — "The Year of the Dragon" in Asia. It debuted only months after Millennium Force and surpassed the Cedar Point coaster as the world's tallest complete-circuit coaster. You might be used to getting on a roller coaster and stepping off much sooner than you hoped - scream, scream and it's all over. Not on this ride - the Steel Dragon is quite the endurance coaster. It's so long that you might actually deplete your ability to scream by the end of the record breaking 8,133ft long track, the one record it still holds.

Thunder Dolphin: Tokyo's most terrifying ride

Known for its unique design around buildings in central Tokyo's Dome City Attractions amusement park, the Thunder Dolphin starts off with a dizzying 218 foot lunge at a steep 80 degree angle. You then race around the track at speeds in excess of 80 mph making this impressive 3,500-foot long, 26-story tall a mental joyride. The ride passes through both a hole in the LaQua building, as well as through the Big-O, the world's first hubless Ferris wheel. Thunder Dolphin's maximum speed is 130 km per hour, or 80 miles per hour.
