I drove my 30' motor home towing my car in there with no problem. There is a loop at the end which is passable if there is no one blocking it as what happened to me. However, I got by, parked 100' from him and that evening he came back and left. Guess he didn't like company. There are only a few sites along it as I recall so I would walk in and check it out. It is less than 1000' feet to the back. I was there in November so I can't answer your September question but the traffic was lite and not noisy when I was there. It is a nice site behind a very low hill and hiking available to the west through cattle fences. Have fun.
