It all depends on how close to your venue you wish to be. Smokemont campground in The National park is really nice. It is also the most popular so you may want to try and get a reservation. With traffic concerns and distance from park to Pigeon Forge it could take you upwards of 30 minutes to get to your venue. There are numerous private campgrounds in town, just do a search. They are well kept and will suit your needs but nowhere near the setting as the GSMNP will be. There are lots of things to do and see and loads of great restaurants here. enjoy your stay here.
