Millennium Force is a steel roller coaster located at Cedar Point amusement park in Sandusky, Ohio. Manufactured by Intamin, it was the park's fourteenth roller coaster when it opened in 2000, dating back to the opening of Blue Streak in 1964. Upon completion, Millennium Force broke six world records and was the world's first giga coaster, a term coined by Intamin and Cedar Point to represent roller coasters that exceed 300 feet (91 m) in height and complete a full circuit. It was briefly the tallest and fastest in the world until Steel Dragon 2000 opened later the same year. The ride is also the third-longest roller coaster in North America following The Beast at Kings Island and Fury 325 at Carowinds.
Millennium Force features a 310-foot-tall (94 m) cable lift hill with a 300-foot (91 m) drop, two tunnels, three overbanked turns, and four hills. The coaster also has a top speed of 93 mph (150 km/h). Since its debut, Millennium Force has been voted the number one steel roller coaster ten times in Amusement Today's annual Golden Ticket Awards; as of 2019, it had never been ranked lower than second place. Although Millennium Force has been surpassed in height and speed, it remains one of the tallest and fastest in the world.
