From Del Valle, after crossing over Discovery stayed on the road on the ridge all the way over to Challenger. Went cross country from Challenger to Lake at Hamilton Flat, then cross country up Mt. Lewis. Would not advise using this route, better to avoid lake and descend ranch road around lake, then cross country. 23 miles and 6,000 elev gain on the day, 8:49 car to car. TR is HERE.
Came up from Del Valle, went over Discovery Peak and followed the road going south. Within 15 minutes a guy in a red jeep came up and told us that we were on private land and had to turn around. He then followed us in his jeep until we were back on Discovery. Wound up doing Rose Peak as a consolation. Cannot figure out how we were caught so easily, cameras on Discovery Peak maybe?

Came in via Del Valle, exiting the park before Williams Gulch and re-entering at the Eastern Most part of Ohlone before exiting again to visit Lewis. Came back a different route, hitting Discovery Peak in the process, making it as much as a loop as possible. 26 miles RT. Also visited the Lewis Benchmark, which is not at the summit. Fun!
Long trail run/walk from Del Valle via Discovery Peak. 22 miles, 7 hours.
With Bob, Steve, and Ben. Cool, obscure peak. Also hit up Discover and Pt. 3841 on this hike.
No easy way to get this one, though it's all on trail or ranch road. Trip Report.
Del Valle through Ohlone Wilderness then East to Arroyo Valle after reaching Mount Lewis. 25 Miles. Photos from this hike
