What is the first giga coaster and where is it located?

The first giga coaster is Millennium Force, located at Cedar Point in Sandusky, Ohio. It opened in 2000 and is notable for its height of over 300 feet, which distinguished it as the first roller coaster to exceed that height, classifying it in the giga coaster category. This distinction was significant in the roller coaster industry, representing a new level of thrill and engineering achievement.

Additionally, Millennium Force set a benchmark that was followed by subsequent giga coasters, influencing the design and construction of future roller coasters. Its innovative elements, including steep drops and high-speed turns, have made it a cornerstone attraction at Cedar Point, often ranking among the top coasters in the world.

While the other options might refer to impressive roller coasters, they do not hold the title of the first giga coaster, which cements Millennium Force's place in roller coaster history.
