It was clear and cool when I started up Calabasas Peak fire road from the trailhead on Stunt Road.

Several good trail runs and hikes start here; among them are out and backs to Calabasas Peak and Saddle Peak and an adventurous loop up Topanga Lookout Ridge to Topanga Lookout and Saddle Peak. This morning’s trail run was also going to be a loop, and it was a loop that I hadn’t done before.

Two-thirds of a mile of uphill on the dirt road brought me to a bench and the top of Red Rock Canyon. This is also where the use trail up Topanga Lookout Ridge begins. This time, instead of starting up the ridge, I turned right onto the fire road and began the winding descent into Red Rock Canyon.

In the canyon, there are Sespe Formation sandstone rock outcrops with a variety of intriguing shapes and colors. About a mile from Calabasas Peak Mtwy is the parking area for Red Rock Canyon Park. From here, the road continues a little less than a mile to Old Topanga Canyon Road.

Running 1.5 miles on a narrow canyon road with little or no shoulder can be hazardous to your health. Doing the run early on a Sunday morning helped. There were about the same number of cyclists as cars, and there weren’t that many of either. The diciest part was a section of road with no shoulder on a blind curve. I was glad to get past that and to the Hondo Canyon Trailhead.

Hondo Canyon is one of the many memorable sections of the Backbone Trail. From Old Topanga, the trail climbs through oaks, grassland, chaparral, and California bay for about four miles to the Fossil Ridge Trail. The trail hides the 1600′ elevation gain well, and long sections of the trail are runnable.

Just below Saddle Peak Road, the Backbone Trail turns right and follows along Fossil Ridge three-quarters of a mile to the service road used to access Topanga Lookout. A left turn leads to the intersection of Saddle Peak Road, Schueren Road, and Stunt Road at the Lois Ewen Scenic Overlook.

The remainder of the loop follows the same route as the Topanga Lookout Ridge – Saddle Peak loop. Initially, it follows the Backbone Trail west, past a large water tank to a spur trail that goes to the twin summits of Saddle Peak. The West summit, with all the electronics, is slightly higher, but is now closed. The flat East summit is about a quarter-mile from the Backbone Trail.

Returning to The Backbone Trail and continuing west, it’s about 1.25 miles down to the Stunt High Trail junction. From there, it’s another 2.6 miles on the Stunt High Trail down to the Calabasas Peak/Stunt High trailhead and the end of the 14.3 mile loop.

Here is an interactive, 3D terrain view of the Red Rock Canyon – Hondo Canyon – Saddle Peak loop. The Topanga Lookout Ridge route is also shown. The map can be zoomed, tilted, rotated, and panned using the navigation control on the right. Track and placename locations are approximate and subject to errors. Poor weather and other conditions may make this route unsuitable for this activity.
