I was going to give 5 stars but then I thought of a few things that brought it down 1 star.  Rangers / camp store is only open 9am - 5pm.  Period.  When you check in you're on your own.  Signage to sites was not the best - if you are trying to find it in the dark... good luck.  

BUT - Smoky Mountains!!!! It's pure magic, and if you go to Gatlinburg or Pigeon Forge you will be SO HAPPY to get back to your peaceful campsite.  

I will come back!!!!!
