Some of the notable rapids and obstacles on this section of the river include the Staircase Rapid, which is a Class III rapid with a steep drop and large waves, and the Big Kahuna Rapid, which is a Class IV rapid with a large hydraulic feature that requires precise navigation.

It is important to note that the Whitewater River Run falls under the jurisdiction of the Bureau of Land Management and has specific regulations that visitors must follow.

Whitewater safety

Check the flow before you run
Use the linked-gauge card and Regional Flow panel above. Class ratings change with flow -- a Class III at low water can become Class IV+ at high water.
Know your skill ceiling
Pick runs comfortably below your ceiling. Cold-water and big-water runs raise the consequences of any mistake.
Wear the right gear
Helmet, PFD, drysuit / wetsuit when water is below 60°F. Throw bag, knife, and whistle on your person, not in the boat.
Scout, set safety, and run with a team
Scout new rapids on foot, set safety with throw bags above the consequence pool, and run with at least one other competent paddler.
Respect the river
Strainers, undercuts, low-head dams, and wood can kill at any class rating. When in doubt, portage.
