Penstock Ridge is a little peak that stands in the lower reaches of Lytle Creek in the eastern San Gabriel Mountains. A gentle fireroad ascends its crest providing great views of the eastern San Gabriels and western San Bernardinos. This is a good quick hike in cool weather. This could be a good peak to combine with trips to Chalk Peak, Lower Lytle Creek Ridge, San Sevaine Lookout, and Buck Point.
Take the I-15 to the Sierra Exit in Rialto. Turn west towards to the town of Lytle Creek. Drive 3.5 miles as the roads turns sharply to the right with a large turnout on the right side. Park here near the dirt road entrance. On the topo this turnout is just after Turk Point.
Round trip is 3 miles with around 700 feet of gain.
