I stayed here on a lollipop backpacking loop I did in the Smokies. While I was there, it was raining fairly heavily for my entire trip, which obviously hampered my camping experience a little.
This campsite is slightly remote for the Smokies, and I had to do a bit of bushwhacking to get myself back there at the end of the trail. I was the only person there—did not see a single person on any of the trails around there for two days. So, if you're looking for seclusion in the most visited national park in the country, this is where you'll want to go.
All-in-all, the rain was a damper, but it's a nice stop overnight for a backpacker. Just don't plan on spending multiple days there.
