The first few miles of it off the highway are paved, but it still turns into sand/ dirt. It is not too bad, but I will still refuse to take my toyhauler down it. It beats everything up too much. You could get through with a 2WD, but you may want 4WD if you are towing a big trailer.
I just took it over Labor Day weekend at Coral since I didnt have by hauler that weekend.
