Similar to three other coasters at Cedar Point, Gemini was at one point the tallest and fastest coaster on earth. Now that was way back in 1979, but it is still a very fun coaster. It is a steel racing coaster with a wooden structure, so it is often misperceived as a wooden coaster. It is not an extremely intense ride, but there some pops of airtime and it is always fun to have a race with the other train!
Because it usually has two trains running on each side (2x2=4) the line is never too long and it goes very quickly, so anytime during the day is a fine time to ride. Since it is in the back of the park, the line is a lot shorter in the mornings though.
The very front seat is my favorite spot on this ride because it gives the best airtime, and you can see the track and the other train in front of you which is always fun (unless you're winning, of course). It is hard to tell which side will win because the ride operators will also let one of the trains leave the station a little early, so it's all up to luck if you want to win!
The height requirement is only 48 inches, and this is definitely a coaster a child would enjoy. Oh, and don't forget to notice the very '80s looking logo!
