There are two Norris Dam campgrounds; the East (25 RV sites) and the West (50 RV sites). We visited the West Campground. If GPS’ing it to this campground, double check the actual address as the address listed on most of the info available is the address to the office and not the campground. The two are not collocated!
Being just off of Interstate 75, it was a short 15 minute drive to the West Campground. When I first entered the park, it was easy to tell it was part of the state park. Trees were everywhere with no apparent thinning for the RV park.
The park, for this visit, was lightly populated with very few sites occupied. If nature is what you like, with little else readily available, this west park fits the bill. The eastern park, which I did not visit, is located much closer to those extra amenities (pool, etc) according to the website.
The state website was a bit tougher to navigate in that it covers so much more in the state of Tennessee than just this particular park. But once you fish around in it a bit, there’s a wealth of information to be had.
Park reservations and “check-in” were handled via the phone with no face-to-face interaction at all. One call was shorter with a less knowledgeable person with the second being longer and much more engaging and informative.
