{{main|Whitewater kayaking}}
One of the most common uses of kayaks for hobbyists is whitewater kayaking. Whitewater kayaking is when a kayaker traverses down a series of rapids. The difficulty of these rapid ranges from Class I to Class VI. The difficulty of rapids often changes with water level and debris in the river. Debris that inhibits a kayaker's path are often called "strainers" as they "strain" out the kayakers like a colander. There are often training camps as well as man-made structures to help train kayakers.<ref>{{cite web|title= U.S National White Water Center|url=http://usnwc.org/}}</ref>
