Gemini is a steel racing hybrid roller coaster located at Cedar Point in Sandusky, Ohio, USA. When the ride opened in June 1978, it was one of the tallest, fastest, and steepest roller coaster in the world. It was manufactured by Arrow Development and constructed by Mosser Construction.


Gemini in 1984.

The construction of Gemini saw the park midway extended by 1,140 foot, completing a 3,000 foot midway expansion project which began with the construction of Corkscrew. Cedar Point claimed that Gemini was the world's tallest, fastest, and steepest roller coaster at 125 feet tall and reaching a maximum speed of 60 mph.[1] However, Giant Coaster, opened at Fuji-Q Highland in 1966, was reportedly taller at 131.3 feet. Harsh weather conditions delayed construction, as a result Gemini did not open at the start of the season.[2] The ride opened on June 17, 1978.


Gemini is a twin roller coaster.

Ride experience

The ride begins with both trains being dispatched from the station simultaneously, then making a 90° right turn, traveling through the maintenance bay. The ride then makes another 90° right turn and travels up the 125.3 foot chain lift. Once the trains crest the hill, they drop 118 feet at a 55° angle, reaching speeds of approximately 60 mph. The trains then coast back up a hill, where they slowly make a large U-turn to the left. The coaster then drops about half-way and goes into a camelback, followed by a U-turn to the right. The ride then drops, rolls through another camelback, and into the mid-course brake run. Following the mid-course brakes, the coaster makes another giant U-turn to the left, followed by two small bunny hills. The coaster's finale is a 360° upwards helix, wheres both trains travel in opposite directions.


4 trains with 5 cars per train. Riders are arranged 2 across in 3 rows for a total of 30 riders per train.
