Two things:  (1) You're in for quite a climb getting up to the campground; and (2) there is no cell service, at least for AT&T.  It was also difficult to find, as Google Maps directed us to a parking lot at a trail head that was a good distance away from the campground.

But we loved the campground.   We had a quick overnight touch-and-go, and really wish we could have stayed awhile.  Will definitely stop in when passing this way again.
