Lying partially in the Puente Hills Habitat Authority lands and partially in Los Angeles County’s Peter F. Schabarum Regional Park, this loop through Powder Canyon takes you through some beautiful woodland areas and into a canyon cutting through the Puente Hills before turning around and climbing back over the hills. More popular with equestrians (there are centers and corrals at either end of the canyon), this route appears to be more lightly traveled by hikers than others in the hills. At times, you may end up having the entire place to yourself.

Please note that hours of this trailhead have been reduced — this trailhead is currently open from 9AM-6PM from June 1-September 30th and 9AM-5PM the rest of the year. Be sure to check with the Puente Hills Habitat Preservation Authority for further updates.

This route begins from the Puente Hills Preserve land on the southern end of the hills. Park either at the small equestrian ring or the small spillover lot near the Nogales Trailhead. The trail begins on a gravel fire road just to the north of the equestrian ring. The gravel doesn’t last much beyond the ring, and the trail soon becomes a fairly even dirt road.
