Penstock Ridge

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 ride in cool weather. It would be a good ride to combine with other fireroads in the Lytle Creek Area.

Trail Description

Penstock Topo

The fireroad ascends gently to a intersection, take the right fork towards a large concrete structure. Continue up the road as it ascends the rolling ridgeline. Keep straight at the next fork, or to the right. The roads tops out at the summit and then continues down a little further to a tower. Take in the views and return.

Round trip is 3 miles with around 700 feet of gain.

Getting There

Penstock Ridge

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.

When to Bike & External Links

Lytle Creek is closed to fire and flash flooding quite often throughout the year so check out weather and road reports. Due to the low elevation of the ridge I would ride this route on cool non-smoggy days.

You will need a Adventure Pass to park at the turnout. Adventure Passes are available at many gas stations and grocery stores along Lytle Creek Road at the Exit from the I-15.

Go to San Bernardino National Forest for current conditions.
