The stretch of the Pacific Crest Trail that descends the western slope of the San Bernardino Mountains isn’t known for many popular day hikes, due to its lack of recognizable peaks or landmarks such as Deep Creek Hot Springs. However, for the curious day hiker or traveler wanting to stretch their legs on the drive to and from Vegas, the P.C.T. provides some nice eye candy in the miles immediately east of the Cajon Pass. The 7.4 mile round trip to and from Cleghorn Road as described here provides a good workout with varied scenery. Though there is an abundance of power lines and noise from the nearby roads, the hike is a worthwhile way to spend a morning or afternoon. Keep in mind that there is virtually no shade on the entire route.

0:14 – Leaving the canyon (times are approximate)

From the road, follow the signed P.C.T. as it makes its way through narrow Crowder Canyon, following the pleasant sounds of a seasonal stream.  After 0.6 miles, the trail leaves the canyon, climbs to a meadow and makes the first of four crossings with dirt service roads. After the fourth (1.5 miles), the trail begins to climb more steeply, reaching a saddle at 2 miles where you get a panoramic view to the east. You may notice orange and yellow Burlington Northern & Santa Fe trains on the tracks that parallel the freeway.

The trail follows a ridge, occasionally getting quite close to the edge. At 3 miles, you reach a large bowl where erosion has caused the slope to drop off, leaving behind pink and brown layers that resemble the Sinks of Limestone Canyon in Orange County. The trail then rises steeply around the upper end of the depression before dropping back to its east side. At 3.3 miles, you get arguably the most impressive view on the hike: the sinkhole dropping immediately in front of you with Mt. Baldy, Telegraph Peak and the eastern end of the San Gabriels in the distance. At this point you are above the majority of the power lines, so they don’t block your view as they do on the lower portion of the trail.

The next 0.4 miles don’t offer much new in the way of scenery, but for those who like seeing things through to the end, you can make your way through a meadow to meet Cleghorn Road. On the return, when the power lines don’t block the way, the views of the San Gabriels are quite impressive.
