Here I am, going to ruin it... no, really pretend you didn't read this... The main campground is nice, it has some great group spots, and some close sites, even a few semiprivate ones. After all it is a campground build on an old section on RTE 16.  The campground as others have mentioned is right on the river, and a wonderful river it is.

This is primitive camping, no water, no electrical, but it does have pit toilets and boat rentals and a day use area.

The hidden spots though are totally private and not at the main site but else ware on rte. 16, the ranger told me about them.  They are amazing (I didn't say that)

Access is easy for any vehicle, minimal cell coverage.

They are currently doing a dig and finding some amazing artifacts!
