Mile Hi Rafting Rapids Classification

White Water Rapids with Mile Hi Rafting!

If you have never been white water rafting, or if you go frequently but have questions regarding the classification system, Mile Hi answers all your questions in this two part series on White Water Rafting! Every river is rated on a scale to help determine the size and technicality of the rapids. This helps rafters to know what to expect and how to prepare. The classification system is only a guide, however. It can also change by season, depending on the water level.   Clear Creek has a wide variety of class levels. Did you know Clear Creek offers more rapids per mile than most rafted rivers in the state? There’s something for everyone, rapids perfect for families and beginner rafters to extreme adrenaline junkies. Let’s take a look at the classification system of rapids and check out what is around the bend!

Classes of Whitewater


Class 1: Moving water with very few riffles and small waves. Few or no obstructions.

Class 2: Easy rapids with smaller waves, clear channels that are obvious without scouting. Waves up to three feet tall, which are easily seen. Some maneuvering is required during this little rock and roll.

Class 3: Waves up to four feet tall and narrow passages that send the boat shimmying and water typically spills over the side. Lots of excitement!

Class 4: Long, difficult rapids. Narrow passages, and turbulent water that requires precise maneuvering. These rapids send your heart racing!

Class 5: All of the above, in addition to large, complex, gushing rapids, twisting, and spinning water rapids. Extremely difficult, and very violent, long rapids with highly congested routes. There is a significant hazard to life in the event of a mishap. Raises blood pressure, delivers an adrenaline rush!

Class 6: The ultimate extreme, only the most expert should try this one. Commercial raft trips don’t attempt this. Nearly impossible and very dangerous, for teams of experts only. For the rest of us, try the other rapids!
