Pine Valley Road is a rural single-lane highway located in the Gabilan Range of southern Monterey County. The roadway originates at the former alignment of US Route 101 along Cattleman Road and extends nine miles north to California State Route 198 in Long Valley. Pine Valley Road appears to have been plotted after the Southern Pacific Railroad was extended through San Ardo during the late 1880s.

There are also two Pine Canyon Roads in Monterey County. They are 1) just southwest of King City (off of Jolon Road just south of the US 101 interchange) and 2) off River Road just south of the Las Palmas neighborhood (a few miles south of the CA 68 / River Road interchange).
Of course the Google car bailed right when the King City variant turned dirt. That likely is the most interesting part of that road.
