Serrano Valley – La Jolla Valley Scenic Loop

Lynn and Frank at the ranch in Serrano Valley.

This is one of my favorite medium length trail runs in the Santa Monica Mountains. It starts at the Ray Miller trailhead and explores the scenic grasslands of the Serrano and La Jolla Valleys. Along the way there are spectacular ocean and mountain vistas from the Ray Miller Trail and the summit of Mugu Peak.


Serrano Valley
Most of the route is on single track trail, and except for a short out & back segment to “The Ranch” in Serrano Valley, it is a complete loop of about 20 miles. Many variations are possible.

One of the better online maps I’ve found of the area is an Interagency Trail Management Map produced by the NPS Santa Monica Mountains National Recreation Area GIS Lab. It shows the status of trails and public lands in the Santa Monica Mountains and is broken into three parts: WestCentralEast. Additional NPS SMMNRA trail management plan maps include Proposed Backbone Trail Facilities and Trails and Proposed Regional Trails.

Here is a Cesium browser View of a GPS trace of our route from the Ray Miller trailhead and through Serrano and La Jolla Valleys.

More Afternoon Daylight!

If you live in the Los Angeles area and do your weekday trail runs in the afternoon, you have reason to cheer — today the sun will set a little later. You can run (slightly) longer before you start to stumble on those unseen rocks.

According to the Astronomical Applications Dept. of the U. S. Naval Observatory, yesterday in Los Angeles the sun set at 4:44 p.m., and today it will set at 4:45 p.m.

The more northerly your latitude, the later the date before the afternoon begins to lengthen. This year, in Miami it was back on December 4, and in Seattle it will be on December 17. In Anchorage it won’t be until December 19. Barrow, Alaska won’t see a sunset (or sunrise) until January 23!

Gradually at first, afternoons continue to lengthen until July 5, when once again the amount of afternoon daylight slowly begins to shorten.

The Hill Climbing Helper

Trail runners, do you suffer the embarrassment of continually being passed on hills? Legs aren’t what they used to be? You need the new Hill Climbing Helper®.

The Hill Climbing Helper’s portability is the key! The Hill Climbing Helper® may look heavy, and it is, but that’s part of the genius of its design.

  • Can be used on all your favorite trail runs!
  • Fits most hills!
  • More effective than elliptical or stair-climbing machines!
  • Increases safety. Eliminates fear of slipping or falling.

Includes 10 stairs and 2 hand rails. Constructed of the finest oil field steel – it will last for decades!

You’ll notice the HCH difference on your first run!

Sunset Shower

Sunset Shower

Some outstanding evening runs this week. Did a FiveFingers run out at Ahmanson on Tuesday, and as sometimes happens this time of year, didn’t make it back before dark. Was up on Lasky Mesa in the fading light, with endorphins at full flow. In a distant grove oaks I could hear a Great Horned Owl, and with each hoot-whoo it seemed the zeal of the day was turning to the tranquility of the night. The running was effortless and ethereal.

San Fernando Valley lights.This evening’s run was also superb. Over the course of the run, the skies had become increasingly gray and troubled, as a weak cold front approached the area. Climbing a long hill, the light was dank, and I had given up on the sun. But as I neared the crest of the hill, orange-red sunlight began to illuminate the clouds from below, highlighting a sunset shower. Large, cold rain drops began to patter around me, and I watched mesmerized, as the light, clouds, and rain played on the sky.

Mountain Solitude

Descending from Pallett Mountain on Pleasant View Ridge, in the San Gabriel Mountains.

It was a little eerie. There wasn’t so much as an animal track or old bootprint on the trail ahead. The path was perfectly smooth, and I felt a bit guilty as my running shoes left their patterned tracks under foot. Lynn, Frank, and I were working up the Pacific Crest Trail on the west side of Mt. Williamson in the San Gabriel Mountains, near Los Angeles. As we switchbacked up the trail, the mountain seemed to sigh, happy to have enjoyed at least a few days of solitude.


Angeles Crest Highway
Closed in early September by the Station Fire, this part of Angeles National Forest did not burn. It reopened in October, but is difficult to access because of the continuing closure of Angeles Crest Highway. To get to this point, we had run from the Antelope Valley side of the mountains. First up the South Fork Trail to Islip Saddle, and then along Angeles Crest Highway, through the tunnels, to the PCT near Kratka Ridge. A steep climb up the PCT put us where we were now — nearing the summit of the usually busy peak.

Of course that was part of the fun of trail running. By the time we reached the summit of Mt. Williamson, we would have gained about 3600′ of elevation, and would be a little more than half way through our 21 mile run. From Williamson’s summit we would head west along Pleasant View Ridge, and then descend the Burkhart Trail to Devil’s Punchbowl. The ups and downs along Pleasant View Ridge, and the “minor” climb out from Cruthers Creek, would add another 1500′ or so of elevation gain.


Big horn sheep track
The run up the rugged South Fork trail had been interesting. Low on the trail we had picked up the blocky hoof prints of what was probably a large bighorn sheep. Intent on the tracks, and telling stories of Tom Brown and the Pine Barrens, we almost didn’t notice two deer hunters hiking up the trail ahead of us. Another mile or two up the trail we heard something large moving through the brush, and were surprised to see  a sizable black bear bounding down a slope. I wondered if it might be the sire of the cubs we had seen on this trail earlier in the year. A little higher still, we found a beautifully colored California mountain kingsnake, warming itself in a patch of morning sun.

Those encounters had been a couple of hours before. Now we were just below Williamson’s summit ridge. Reaching the crest, we ran the few remaining yards to its eastern summit. The visibility was stunning. To the south, we could see the thin ribbons of Catalina Island and San Clemente Island, more than 75 miles distant. To the east, Mt. San Jacinto loomed above the shoulder of Mt. Islip. To the north an indistinct line of white floated above the horizon. Was it the Sierra?



The 3 mile traverse of Pleasant View Ridge between Mt. Williamson and Burkhart Saddle was strenuous, but spectacular. The path along the ridge was also untrodden, and it wasn’t until Pallett Mountain that we noticed the first footprints. From Pallett Mountain the route dropped more than 3000′ — much of it excellent running on the Burkhart Trail. It wasn’t until mile 20, when we turned off the High Desert National Recreation Trail and started the mile descent to the Devil’s Punchbowl parking lot, that we finally encountered another person — a runner, jogging up the hill.

Here’s a Cesium browser View of a GPS trace (yellow) of the point to point route, and an elevation profile generated by SportTracks. Using the High Desert Recreation Trail as a connector (red trace in the Google Earth view), the route could be extended to a loop.
