We stayed at the Davis Pond Campground which is about a 15min drive back into the park. If you want to stay here you have to be there before dark as they close the gates at dark. It's basically like having your own small park in the middle of the mountains on a small bass pond. There was one other couple staying there and it was Memorial Day weekend so I would be surprised if you run into many people out there. There are also tons of places to backpack in and camp. We were on the last leg of 3 campgrounds in 3 days so we had our rooftop tent but want to try packing in to one of the many hike in sites. Caught 4 largemouth bass in about 15 minutes of fishing on the pond, largest being about a 1lb. You will deal with some ATV/Jeep traffic during the weekends which can cause some dust to deal with and the pit bathrooms are about as disgusting as I've ever seen. They really should just bulldoze them down and it would make it even better but outside of that this campground is absolutely amazing if you are looking for seclusion. Expect about an hour and a half drive from Knoxville.
