Yes... Bear River Ridge out of Rio Dell. It is about 15 miles of dirt that takes you to the county paved "Lost Coast Road'.
Other back road access to Rio Dell is the 'Blue Slide' road, which leads to Ferndale.
The problem with Rio Dell is that 'south access' is via highway 101... for about 10 miles. (The Avenue of the Giants starts at that point.)
If you can do that much highway, you will be alright.
