We reserved a site at Thompson Flat well in advance last summer. The drive up and into the campground was absolutely exquisite-beautiful meadows with flowers, and tree-covered mountains. You can imagine our surprise when we pulled into the campground and found that the ENTIRE place was completely overrun by large crowds of people. The campsites were all full with multiple vehicles that were spilling out into the road, loud music was playing, and it was almost like a party had rented the entire campground. There were no campground hosts present, and we realized that there was no way that we were going to be able to get a decent night's sleep if we stayed(we were tent-camping). We actually pulled out and left--something that we have never had to do before. I don't know what was actually going on here, and perhaps it was a fluke, but this was so disappointing for a national forest campground. Definitely not the remote, quiet, family camping experience that we enjoy.
