Boulder Canyon to Dough Flat

This route traverses a large section of the Sespe Wilderness in Los Padres National Forest. It travels between Boulder Canyon Trailhead at Ozena Fire Station and Dough Flat Trailhead, utilizing a number of paths along the way: Boulder Canyon Trail, Reyes Peak Road, Reyes Peak Trail, Piedra Blanca Trail, Sespe River Trail, and Alder Creek Trail. These trails are well-developed for the most part, thanks to the hard work of Los Padres Forest Association. The trail does become hard to find at times at water crossings just after Haddock Camp as well as at some crossings of the Sespe. This is a moderately difficult route and just be attempted by experienced backpackers. 

From the trailhead at Ozena Fire Station (just off Highway 33), Boulder Canyon Trail is a steep, exposed climb up to join Reyes Peak Road. The route follows the dirt road for about two miles to Reyes Peak Trailhead. From here Reyes Peak is just under a mile, and our route continues on to follow the singletrack along the ridge to Haddock Mountain. Note that the weather up on this ridge can be much different than the weather down on Highway 33. There are excellent views in all directions from the mountain summits. We descend from Haddock Mountain to Haddock Camp. As of this writing (Fall of 2025), there is a brief, but tough patch of buckthorn to push through on this descent. From Haddock Camp, follow the trail (which can seem to disappear at creek crossings) to the edge of the massif, near Pine Mountain Lodge Camp where we begin a more sharp descent. The Piedra Blanca Trail drops from here, following the North Fork of Piedra Blanca Creek. There is a nice view of the Topatopa Mountains straight ahead along this descent. We join the Sespe River Trail around mile 23, which we follow as it winds along Sespe Canyon. The trail follows the canyon until diverging from the canyon by climbing up to Sespe Saddle, and soon after joining Alder Creek. The route follows Alder Creek Trail, passing the fascinating rock formations at Stone Corral, on its way to the trailhead at Dough Flat.
