The river rapids on this segment of the Whitewater River are exciting and challenging, with notable obstacles such as "Devil's Gorge," "S-Turn," and "Boulder Falls." It is important for kayakers and rafters to have experience with technical rapids and to use proper safety equipment, as the river can be unpredictable.

In terms of regulations, the Whitewater River is managed by the US Forest Service and requires a permit for overnight camping. The river is also subject to fishing regulations set by the Oregon Department of Fish and Wildlife. It is important to check for any current closures or restrictions before planning a trip to this area.
