Seriously, if you go here, call the BLM for road closures and detailed instructions. And then prepare to get lost anyway. Add in very agressive log truck drivers on a fairly narrow road and like the brochure says, "the drive is the adventure". We did "find" a new way out that seemed straighter and involved less time on unpaved roads. It's not in any info I've seen on the place at all and this isn't the possible back way from near Drift Creek Falls. This brought us out near Fort Hoskins Historic Park by Kings Valley, totally avoiding Valsetz/Falls City and hitting Highway 223 about 15 miles south of Falls City. We knew at some point we were on the 'wrong' road but decided to follow it and see what happened. Go figure.. it actually worked 
Going on a weekend should eliminate the log truck issues. A lot of the road goes thru private property and gated roads. Once fire season starts, the gates/roads will be closed to the public.
