Looking for an adrenaline rush? While rafting on any river any time is a guaranteed good time, many paddlers are looking for the ultimate in excitement and challenge. If that's the case and you are ready for an extreme test, you'll want to try rafting a river with Class 4 or 5 rapids. We've outlined the Class 1-6 classification system of rapids in our Rafting 101 section. Class 4 and 5 rapids are generally the most challenging that a professional rafting company will run commercial rafting guests. You should be in good physical condition and be a strong swimmer in case you find yourself floating through one of the rapids on your own!Below is a list of popular Class 4 and 5 runs in North America, many of which are offered by Riversearch.com members. Please remember that Class ratings do vary with river levels and other factors. A Class 4 run may be a Class 5 river in high water or seem like a Class 3 river at low water. So ask the outfitters what river levels are likely to be like on the day you come rafting. Most will not be able to give you exact river flow information, but in general, they can tell you what the river is normally like during the time you are coming.
