Idaho's Lochsa River, the name of which literally means “rough water,” is one of the best spring whitewater rafting runs in North America. You can see what it takes in this video. A typical trip will have you raft along big, fast and technical big volumes of water. Section Two is known as among the most dangerous. Unending, explosive rapids are especially tough on the second section and when the water rises above six feet the rapids often run into one another, creating a continuous trail of rough water. Though commercial rafting companies run this river, it is dangerous and has taken several lives, according to American  Whiterwater.
