Ninja is a roller coaster in Samurai Summit at Six Flags Magic Mountain. It's worth seeing on a time-permitting basis. The minimum height to ride is 42 inches.
A suspended coaster that flys over the tree's and hills. You twist and turn above Jet Stream(Arrowhead Splashdown), and end at the bottom of the hill. Don't be fooled by the second lift hill, it's not into another drop. Just into the station.
