Driving Directions
Take I-15 to the Hwy 138 exit below the Cajon pass. Take Hwy 138 EAST toward Silverwood Lake. Continue on 138 a few miles after the road straightens out. Make a left onto Hwy 173 toward Hesperia. Take 173 to the only major left turn at Arrowhead Lake Rd. (If you stay on 173 until it becomes dirt and starts winding up the mountain, turn around, go back a mile and make a right onto Arrowhead Lake Rd.) Take Arrowhead Lake Rd about 4-5 miles to Hesperia Lakes on your right. Park in the main lot by the store. This is probably the better way to go if you're coming from I-15 North.
From Hesperia Lakes, ride south on Arrowhead Lake Rd to Highway 173. Make a left. After one mile the road becomes unpaved for the next 5 miles. Continue about 3 miles more after the pavement resumes to a ranger station on your left. The water here has been turned off. Across the street from the ranger station is Pilot Rock Rd 2N33. Make a right here and ride about 3 miles to obvious Pilot Rock, walk up to the top. Continue down the other side and continue along the ridge top on Pilot Rock Rd. Most of it is downhill from here to the dam on Silverwood Lake. Stay on Pilot Rock Rd, the main, best quality road out there all the way to the paved road at the top of the Cedar Springs dam. Make a right here down to Hwy 173. Make a left and ride about 1.5 miles to Las Flores Road at a sharp bend in the highway. Take a powerline road to Las Flores Rd and continue on it into Hesperia. Make a right onto Ranchero back to Arrowhead Lake rd and make a right back to Hesperia Lakes.
Nice day, temp not above 60-something mostly. Poor air quality. They said Lake Arrowhead got about 10 inches of rain in the last week... you'd hardly know it, the roads were pretty dry. It was so dry up there it all just soaked up. Just a few puddles, but nothing big, couldn't get muddy if you tried (and I did try, I always do). The rains compacted some of the sandy portions, especially along Las Flores Rd, making almost everything rideable, whereas usually there's some walking to be done.
Trail Condition
Pilot rock road was in the worst shape I've ever seen it in... rocky and rutted. Usually it's a hands off the brakes fun downhill of 20-30 mph, today it was more like a jarring 15-20 mph.

I set some new personal record times up Hwy 173 today. Although my old times are from when it was 7 miles of dirt.
From base of Hwy 173 to grate near shooting range: approx 50 minutes, old time was 53 minutes.
From start to the grate at the top of the end of the old dirt road near the shooting range: 1:18:35
From start to ranger station: 1:23:30
From start to Pilot Rock: 1:52:00

There was a 3/4 ton truck that was going slow and steady up Hwy 173. They passed me early on. After a few miles, I caught up and passed them and stayed ahead of them to about 1/2 mile beyond the beginning of the pavement, that made my times faster than they would have been.
