Its Pitch Black And YOu Free fall most of the time.... you get a bit of a jerk at the end. though
There are three curving body slides, Rudder Buster, Stern Burner and Jib Jammer.
Each slide gives you a different experience, and are some of the most fun slides I have ever been on. They arent the fastest, steepest, longest, but just plain fun. They have a very high re-ride capacity.
One word of warning though, you need to be pretty fit to keep riding these over and over, as the steps up to the top are long and winding.
