Upper Sacramento River – Class III

A challenging and dynamic run of action-packed fun


The Upper Sacramento River between Sims Flat Campground and Dog Creek Road is a challenging and dynamic run, having nearly 50 Class rapids of non-stop fun. Some rapids are long and continuous and some are pool and drop. Water seems to come from everywhere as numerous side streams tumble into this lush canyon. There is easy access from I-5 and views of nearby Mt. Shasta.
