I'd go about 200yrds from my front door.
(Sorry bout the rifle,,,, that's the only pic I could find.)
Ironically I have one of the best holes on the Clearwater right in my front yard but have no interest in Steelhead fishing.
As stated above, the Clearwater really is one of the premiere Steelhead fisheries.
If you're self contained there's a sweet little campground right on the river about three miles upriver or there's others with hook up's scattered along the river. I can put you in contact with some good guides or chase down any other info you need for the surrounding area. PM me for my phone# if I can help.
