OK
We camped here once because it was easy for part of our family to get to from NYC. Sites were a little too close together and one of the sites we reserved was filled with broken glass, we did call the park office and they promptly sent someone out to clean it up. Bathrooms were clean but there wasn't soap in any of the dispensers. If you're truly looking to get away from it all I would go elsewhere since the parkway runs through/over the park, you will be able to hear traffic noises. That said, this is probably a great place for those who have not camped before, it's easy to get to and close to civilization.
