A long dirt road takes you winding up switchbacks into a beautiful mountain scenery. I managed to get through alright in a newer model Honda Civic Sport, but wouldn't suggest it if there was any snow on the ground.
In some of the pull offs into the designated sites you may or will need a 4x4 to access. I had no service (AT&T), there are no water sources that I saw and of course no bathrooms or electrical plug ins here.
This entire area is at a slope, so you'd be hard pressed to find somewhere flat to set up your tent if you have one. This area would probably be better for hammocks, and for that reason I am deducting one star because the area is quite beautiful.
