Could not have gotten much closer without being IN Gatlinburg. The pictures don't really show it well, but the sites are pretty close together. Your picnic table is almost on top of the other person's sewer hose. In our site we put our table towards the back.
I will say that I was able to sit for a while on some of the bigger rocks by the creek with my dog and it was so extremely peaceful.
They had such a nice playground for all ages. The park was also decorated nicely for the holiday. The staff was out and active. I wish we had stayed here all week so we could have taken more advantage of the other amenities. Super dog friendly as well, with several poo stations set up - just be careful of random other campers who let their dogs potty on your site without cleaning it. It can be hard to see in the gravel.
