Watts Valley Road is an approximately 18.6-mile rural highway corridor in the Sierra Nevada foothills of Fresno County. The corridor begins at the eastern terminus of Ashlan Avenue and passes through the namesake Watts Valley where it terminates a Burrough Valley Road. Watts Valley is named after Texas miner Charles B. Watts who settled in the area during the 1850s. Modern Watts Valley Road can be seen on maps shortly after the Copper King Mine opened in 1900. The corridor has historically been known for wildflowers and was designated as part of the Fresno County Wildflower Trail in 1998.
