If you are planning a trip to the Smoky Mountains, I can definitely recommend this RV resort. It is located just of of I-40, behind Smoky Mountain Knife Works. It's actually in Sevierville, and about a 15 minute drive on in to Pigeon Forge, but this is an outstanding place, that is kept immaculate. Blacktop drives, concrete pads, cable, and a very nice swimming pool. The 5th wheel sites are all river view, overlooking the French Broad River. They park Class A's in the river front sites, but all sites get a very nice view of the river. Very easy parking for big rigs. They people that run this place are super friendly, and will bend over backwards to make your stay very enjoyable. There are RV parks that are closer to Pigeon Forge, but none as nice as this one.
