River Ratings - What They Mean

Class I	Relaxing - gentle floating - It is considered as flat water, little current and mild waves like a swimming pool.
Class II	Easy Does It  - Moderate waves, clear passages
Class III	Adventurous - waterslide-like waves, clear passages - This will gives you waves, swift current and narrow channels. Paddling is modestly physical.
Class IV	Thrilling - Powerful waves, big drops
Class V	Awesome - big waves, technical drops and steep grade  - This grade has powerful water, constricted channels, steep drops and the possibility of overturning a raft. Paddling is challenging and requires some previous river experience.
Class VI	Impossible to run – Something best attempted after your lover leaves you.

Commercially these are the rivers for rafting, kayaking and canoeing where your rafting trip will be accessible and carried out:
