Hey there,
I went hiking up there last January. We drove from Temecula and made our way up a mountain and started the hike at a trailhead there. I don't remember the directions exactly, but I will ask my friend and get back at you with more information.
I do remember seeing a lot of no-entry signs, but we figured it was for the side roads that were there.
We hiked 9 miles up until we reached the Eagle Crag summit, then 9 miles back down. We even hid a geocache there, which you can find here (it's a premium member cache):

Here are some pictures of the trip:

We followed mountain lion tracks for a good 3-4 miles...it was very exciting.
I will let you know about the directions ASAP.
Take it easy.
