When Bolliger & Mabillard designed and created the first inverted coaster, Batman: The Ride at Six Flags Great America, they hit the nail right on the head. Batman is a great ride, but with their second go at an inverted roller coaster in 1994, Raptor, they took another great leap forward. Out of the many inverted coasters I've been on, Raptor is still my favorite. It is the first coaster you see when you walk into the park, and at 137 feet tall with six inversions it certainly stands out.
Because of its location right at the front of the park, many guests immediately queue up for this at the beginning of the day. Though you may be tempted, if you can hold out riding it until late afternoon (after four) the line will be much shorter. Raptor's line is always fast moving as well, so even on the busiest of days, a long line can move very quickly.
Waiting for the front is only an extra five or 10 minutes, so I highly recommend waiting; it is well worth it! Otherwise every other seat is basically a similar great experience. The back is a bit more forceful and usually causes me to grey-out a bit on the pullout of the first loop into the second zero-g roll inversion.
The on-ride photo is taken during the final helix so make sure you're smiling! :) The height restriction is 54 inches, and it is also quite accomodating for larger guests.
This is a must ride! Do not leave the park without kicking the sky on Raptor!
