Drove up to the Santa Clara Divide, from there there are numerous forest service roads branching north from the top. Most of it is pretty easy 2WD stuff, but every now then there is a short spur off to the side that will climb up a steep hill side, definately 4wd needed.
Eventually, if heading east, the road becomes paved and runs into Angeles Forest Highway, but from there you can pick up another fun forest service road to Mt. Pacifico. Once again, easy stuff. But the scenery is beautiful and the views are amazing.
