Good facility and lots of fun for our family. No water there but that was the only inconvenience.

The only issue we had was that the reserved sign was not put out and people were trying to take our spot. We called in and was told no one could do it because of being understaffed. But yet a Forest Service person was there 5 different times, once within a couple of hours after we were told no one could come. Things were well kept, bathrooms were fairly cleaned and maintained. We will stay there again.

Camping at Thompson's Flats is a great experience after you chase other campers out of your reserved camp sites. Every time we have a family reunion in Loop A we show up to set up camp and there are other campers already in our spots and we have to tell them to leave. There is no camp host, ranger, or after hours phone number to call to get to help. How the sites are marked reserved are a joke and something different needs to be done so there is no confusion or misunderstanding.
