List of Colorado River rapids and features

The following is a list of major rapids and other notable features on the Colorado River, in order of their position downstream of Lees Ferry. Ratings are given for how difficult the rapid is to navigate by whitewater raft or other water craft. The Grand Canyon, like other big-water Western rivers, uses a scale of 1-10 for rapids, 10 being the most difficult. (The Class I-VI classification of rapids is more common elsewhere in the US and internationally.)
