Warren Peak
What to Expect
Safety Advisory
The route is unmaintained with no signs past the backcountry board — losing the trail is common, especially on the descent when washes all start looking the same. A GPS device or phone app with offline maps is essential, not optional.
Rattlesnakes are active in the rocky terrain from April through October, particularly along the wash sections where they shelter under boulders. Watch where you place your hands when scrambling.

Pro Tips
Start from the Black Rock Canyon backcountry board and follow the wash northwest — the turnoff toward Warren Peak is easy to miss, so download the GPX track beforehand rather than relying on cairns alone.
This trail has zero shade above the initial juniper zone, and the exposed ridgeline radiates heat like a parking lot. Carry at least three liters and start before 7 AM from October through April to catch cooler temps and the best summit light.
The summit block has a use trail wrapping around the left (south) side that's far easier than the direct scramble up the front face — look for it when the route seems to dead-end at a rocky wall near the top.
