From the parking area within the park, follow an old road (still paved but obviously not used in many years) briefly into the hills. Where the road loses its pavement at some large boulders... this is your start.
Follow the road into the canyon. It will become dirt soon. This is an old road that has been bulldozed and turned into a hiking trail. As a result, the steepness is very gentle - the drawback is that you have to walk further to gain your elevation. In any case, about two miles of hiking up this road/trail brings you to a pass called Mundy's Pass. Here, the road is much more substantial and it does appear to see vehicles now and then, coming up from some place else. Bear right and drop about 100 feet, then simply stay the course and follow the road as it switchbacks to the summit. The summit has been graded flat and there are a couple of electronic gizmos on top, which presumably 'justifies' the need for the road you just walked up.
It's about 4 miles o/w, about 2,000 feet of gain. Despite the sometimes unattractive road cuts, the views in the range and over the deserts are outstanding.
Just good hiking boots, sun block, hat... the usual. No cross country hiking to worry about.
