CLASS II: Easy rapids, waves up to three feet tall that are readily seen, and wide channels that can be discovered without scouting. Some maneuvering is required during this little rock and roll.
CLASS III: Waves up to four feet and narrow passages that send the boat shimmying and water gushing over it's sides. Plenty of excitement.
CLASS IV: Long, difficult rapids, narrow passages, turbulent water that requires precise manuevering and sends hearts racing.
CLASS V: All of the above and then some - large, complex, gushing rapids, twisting, and spinning to deliver the consummate adrenaline rush.
CLASS VI: The ultimate extreme, only the most expert should attempt this. Raft trips don't go here. There's too much other water to enjoy.
