Go north 24.5 miles on SR 99 to SR 58.
Go east 7.1 miles on SR 58 to Weedpatch Highway (SR 184).

Go 33.5 miles east on SR 178 to the intersection of SR 178 and SR 155. This road is scenic as it follows the Kern River, but is very winding.
Alternatively, you can reach the intersection of SR 178 and SR 155 from Walker Pass (please refer to your AAA map). This route is about 20 miles longer from Sylmar, but the road is not as winding and those traveling from the east might find it shorter.

Go uphill on SR 155 for 7.7 miles to Greenhorn Summit.
Turn right onto 24S15 (dirt). Note your odometer and go as follows:
At 1.2 miles, a fork to the right. Turn right on 25S16. (This is the turnoff for Sunday Peak.)
At 2.8 miles, a fork at a saddle. This is Black Mountain Saddle. This is the parking area for Black Mountain #5. Keep left. The gate at Black Mountain Saddle may be closed, adding 2 miles each way.
At 3.2 miles 2WD vehicles should park. High clearance vehicles can go another 2 miles, to an old road on the right, with a large parking area on the left, a remnant of a timber cutting operation.
