Fall River Valley

The Fall River Valley is nestled between the Sierra Nevada and the Cascade mountain ranges in the far Northeast corner of Shasta County, California. The town is surrounded by mountains in all four cardinal directions with Mount Shasta and Mount Lassen visible from anywhere in the Fall River Valley. The valley is well known for its fertile farm land, and  Fall River;  a 21 mile Spring creek, designated a heritage wild trout fishery. McArthur is home to the Inter-Mountain Fair.
