First you will needs some decent maps. The DNR public lands Quadrangle are a decent choice. These can be ordered on line from DNR. You will want the Forks and Mt. Olympus maps. Take some time and look at Google earth, the county Maps sites. You can also down load ArcGIS explorer (free) that has some good orthos and maps. With this you can down load layers from various sources and build you own maps.
Good man has okay to fair access and good elk numbers. You can start with DNR lands and work in from their. The clearwater has great access and decent elk numbers. But, it is rugged! The info above pretty much sums up the camping access. Just about pick your spot.
I also sent you a pm with contact info for someone very familiar with the area.
If you are hunting the clearwater and see a green Jeep stop and say hello.
