How long will you be staying? The closest state park which will be the best rate by far is Panther Creek State Park outside of Morristown, TN. It has been remodeled and they have some full hookup sites now. Also you can make reservations on line for up to a year in advance. Another nice state park is Day Crockett Brithplace State Park outside of Greeneville, TN, again full hookups and an online reservation system. Did you want TN or NC?
