Q: What is a Gigacoaster?
A: Also spelled hyphenated as giga-coaster, a Gigacoaster is a complete-circuit roller coaster with a height of between 300 feet (91 meters)and 399 feet (122 meters). What does that mean? It's very big! Giga!!!
There are only two gigacoasters in the world: Millenium Force at Cedar Point (Sandusky, Ohio, USA) and Steel Dragon 2000 at Nagashima Spa Land (Mie Prefecture, Japan).
The term Gigacoaster was coined in 2000 by Cedar Point to describe Millennium Force, the first roller coaster to break the 300-foot (90-meter) threshold.
