This is a spectacular place if you are looking for private and semi-private dispersed campgrounds that you can drive up to. Great hiking around the area. 

The road to get into the primitive camp area is long, and just a little bumpy but we had no problem in a 4x4, also saw volvos and subarus do just fine.  Sprinter vans would be fine. Was pretty dry when we visited, could see the road getting a little sketch after big rain.  Definitely not gonna be fun for even small RV's. Tough turnarounds for large trailers or 5th wheels.
