No doubt about it: this is the  ultimate!

With a phenomenally steep gradient averaging 110 feet per mile, the Cherry  Creek/Upper Tuolumne run is the most challenging run in the U.S. and the standard by which  Class V runs are measured. This intense and demanding stretch of river in the Stanislaus National Forest comprises long, nearly continuous rapids and only short pools.



"The Creek's" unparalleled array of chutes, holes, ledges and falls, amidst gigantic boulders, include rapids such as Jawbone, Mushroom, Miracle Mile, Lewis' Leap and Flat Rock Falls. A training seminar and Class V paddler's test are  required for this thrill ride.
