Originally a Chumash Indian trail from the coast to the central valley. In 1824 it was the route that Pablo de la Portilla used to return the Mission Indians after their revolt. When Fort Tejon was established the trail was used, for a short time, as a dispatch route between the Fort and Santa Barbara. In 1898 the Pine Mountain and Zaca Lake Forest Reserve was created and this trail was one of the fast Forest Service trails to be mentioned in the 1904 report on trails in the new region. It was the main north south route across the back country of the forest until the 1930's when the VC; completed the Big Pine Buckhorn Road.
