The Clarks Fork is a beautiful river that offers a great challenge for only the most advanced and physically capable paddlers. The river offers challenging rapids, multiple falls and pools, lots of portaging, and careful navigation. There are other access sites along the route allowing paddlers to run only certain sections of the river. This section of the river commonly starts at the W-296 Bridge with some immediate class IV and V rapids through a steep canyon requiring a few portages. Paddlers then continue on through another two-mile stretch of some tough rapids and a six-mile section of calm waters before entering The Box. The Box is a very difficult canyon to paddle. The run is full of boulders fields, holes, portages, and sections that require technical climbing skills. The entire trip requires two days and is very physically demanding. Scouting some sections of the river can be done from trails that follow the river but much of the river is in a gorge without good visibility of the river.
