Another route is I-24 West from Nashville. Stay on I-24 until you get to the 1st Cadiz, KY exit, which is #65 I think. The hwy. # is 68. Turn left on 68 and stay on it. You are 20+ miles from Wranglers Campground.
Keep going on 68 across the loooong narrrrow bridge until you see a sign on the left for the Wranglers Campground. Turn on this gravel road and go until it stops; then turn left on paved road. The camp will be on your right, shortly. Stop at the gate and check in.
