A 17.7 mile trail in the Sespe Wilderness through impressive white rocks to a number of wilderness campsites. Designated a National Recreation Trail in the Los Padres Condor Range and River Protection Act. Named for Gene Marshall, a leading advocate of wilderness designation for the Sespe who played a key role in the development of the Los Padres Condor Range and River Protection Act. In the Ojai Ranger District the Gene Marshall-Piedra Blanca National Recreation Trail offers Wilderness access along an eight and seven tenth mile trail. First half easy, then very steep climb. Drive to Lion Campground at the end of Rose Valley Road. Cross the wide stream bed and take the trail to the left. After about half a mile turn right at the junction. This will bring you through the impressive white rocks and to Piedra Blanca Camp after 2.7 miles. Twin Fork Camp is a half mile further and has water most of the year. Trail to Pine Mountain Lodge Camp is another 3 miles, very steep in places, but well worth the visit. This camp is nestled in the conifers and has water close by. From the junction at Pine Mountain Lodge, the Piedra Blanca Trail continues northwest to Haddock and Reyes Creek Camps. The trail which goes east takes you to Fishbowls or Cedar Creek Camps on the Mt. Pinos Ranger District.
