I took pictures of site #8 for someone last year....

I stayed at site #15 and will be doing the same again this year. Once I got used to the roar of the creek, I slept pretty good. The Lone Pine Creek trail runs past the site, so there is occasional foot traffic (children and fishermen), but I enjoyed watching the kids play and the fishermen fish. Site #16 might be better. It is on the opposite side of the creek from the trail, seemed to have more shade, and is slightly closer to the restrooms than site #15.
Sites #11 and #13 were pretty open, partly shaded under pine trees. My neighbors at #13 last year just layed their bags onthe ground and slept under the stars (mid-July). Across from #15 are sites #12 and #14. I remember them being surrounded by some good size granite boulders on three sides providing a little privacy, but I don't think they had much shade.
Don't think you will be disappointed with any of the sites. Best of luck and have fun.
Kind regards,
