There's a guy who reviewed and thought the paid sites were part of the dispersed camping - he missed the fork in the road where the easily accessible 2wd maintained and fee campground is. If he turned down the other fork, he'd have found the dispersed camping. The road is pretty rough, but our honda CRV handled it just fine.

And the gal who didn't see signs on 4wd recommended... might need to get their vision checked soon. But dirt roads themselves are not 4wd lol. After the paid campground it gets rough.
