The Bear Gulch to Confluence with Middle Fork Feather WSR whitewater river run in California offers a range of class III and IV rapids over its 5.7-mile length. The ideal streamflow range for this section of the river is between 700 and 1,500 cfs, with higher flows providing more challenging rapids and lower flows resulting in technical maneuvers around rocks. The rapids on this run include "Gobbler's Knob," "Jaws," and "Staircase," which offer technical challenges and exhilarating drops.

One of the major obstacles on this run is the "Mamma Rapid," a Class IV drop with a steep gradient and multiple holes to navigate. The "S-Turn Rapid" also presents a challenging obstacle and requires precise maneuvering to avoid rocks and stay on course. The segment mileage for this run is 5.7 miles and typically takes 2-3 hours to complete.

There are specific regulations for this area, including a maximum group size of 15 people and a permit requirement for commercial outfitters. Personal flotation devices (PFDs) are mandatory for all participants, and the use of alcohol or drugs is prohibited. Visitors should also be aware of the sensitive ecological environment surrounding the river and take appropriate measures to minimize their impact on the area.
