North Fork San Jacinto, California Wild and Scenic River (Recreational) · Open Access
This 10.2 mile wild and scenic river system finds its source on the heights of San Jacinto Peak in the Mount San Jacinto State Game Preserve and Wilderness Area. The Pacific Crest National Scenic Trail crosses its upper reaches. Above the confluence of Fuller Mill Creek and the North San Jacinto River is a picnic area and fishing access location. Hike upstream from here to see lovely waterfalls.
This area supports habitat for many at-risk species, including mountain yellow-legged frogs, California spotted owls, the rubber boa, and the San Bernardino flying squirrel.
While there is no camping on the river, there are four campgrounds nearby.
