Trail Overview

This is a short but challenging dirt and gravel trail from San Francisquito Canyon Road to the remainder of the USFS roads in the vicinity of Grass Mountain. This trail is historic in nature as the south portal of the Los Angeles Aqueduct's Elizabeth Tunnel is sealed, but clearly visible from the south end of the trail. From the north end of the trail, views of the Tejon Ranch and the Tehachapi Mountains are visible. Access to the Pacific Crest Trail (hiking only) is easy as the intersection with the USFS roads is right there, and other attractions such as Grass Mountain are nearby.


This trail is not well maintained and may have deep ruts requiring the driver to straddle. A high-clearance 4x4 vehicle is recommended. Additionally, snow and/or ice may be present in winter months, so caution must be taken.
