Getting ThereTake I-10 east past Banning to the intersection with SR 62. Go north on SR 62 to Joshua Lane in Yucca Valley which is also the intersection with SR 247. Turn right on Joshua Lane and drive about 5 miles through the spread out desert neighborhood. You will come to a junction with a sign for Black Rock Campground. Turn right at the junction and head through the campground and park at the visitor center.
Continue south on a dirt road to a fork just before a water tank. Go left for 200', where a use trail goes right from the road. Follow this trail about 1/2 mile to the main Black Rock Canyon wash marked by a toppled sign post. Turn right and follow the wash as it heads southwest and then west to a saddle just south of the peak. Follow any signposts with arrow and "WP" (Warren Point) as they mark most of the junctions. Warren Point becomes visible to the northwest. Leaving the wash and take a steep trail up the ridge that leads to the summit.
The roundtrip is about 5 miles and with 1000 feet of gain.
