It's a fairly easy ride and until you get to three way fork where Co rd 21 and Forest Road 770 intersect you can ride a 2 wheel drive vehicle.
Even after that the ride is not too difficult and a two wheel drive could probably make the journey though I wouldn't suggest it.
Anyway here's the trail, hope you like it...
