We found this by accident while traveling home from a nearby campground. There are a few sites very close to the river with wonderful views. There are no services - bring your own potable water and probably your own toilet paper. Also, on 9/2/13, there was a bald-faced hornet nest in the vault toilet building - you may want to bring a few cans of wasp killer.
I don't have an RV, but I'm guessing this area is too small for a trailer or any vehicle longer than 20'.
We stayed here in a Tent.
