I would think you are heading for the town of Maupin. If so, there are many campgrounds up and down from town. They are primitive BLM sites, meaning outhouses and no running water. There is some 27 miles of road below town to explore and 10 or more upstream. Except for the area imediately surrounding Shearar's Falls, there is plenty of good water. This is also a popular time to be on the river. Don't be surprised to see cars parked before light and guide boats putting on in the dark to "reserve" their spots. By late Sept and through October, there will be plenty of competition and some who don't know or care about the "rules". I try and avoid the crowds the best I can, but each year it seems harder. When in doubt comunicate with your fellow anglers and remember, step in above and your fine!
