The Whitewater River run is a 1.5-mile stretch of river located downstream from Big Spring in California. The ideal streamflow range for this section of river is between 200-400 cfs, making it a great destination for intermediate paddlers. The segment mileage is relatively short, but it packs in plenty of excitement with a Class III rating. Rapids and obstacles to watch out for include the "Crunch" rapid, which features a large boulder in the middle of the river, and "Vortex," which can be tricky to navigate due to its strong eddies.

It's important for paddlers to be aware of specific regulations in the area. The Whitewater River run is located within the San Gorgonio Wilderness, and therefore, no motorized vehicles are allowed in the area. Additionally, visitors must obtain a permit to enter the wilderness, which can be obtained from the ranger station in Whitewater. Finally, visitors should also be aware of the Leave No Trace principles and follow them to ensure the preservation of this beautiful natural area.
