If it’s wilderness then you don’t need a separate bike path because the road itself is nothing more than a one-lane dirt track. Basically, your knobby-tire cyclocross or mountain bike would only need to ‘share the “road”’ with high-clearance 4x4s plodding along at 15 mph or so.
You can have a bike path to the forest preserve going right alongside the road. Or a tram rail.
