Take I-77, exit 20. Turn south on U.S. 19. Wolf Creek Falls is located on U.S. 19 (Beckley Rd) approximately 3.5 miles from the exit ramp of I-77. The falls is roadside at the intersection of CR 19/6. Your GPS will probably want you to take this route (CR 19/6) , and you can, I did just for fun, but it's a pretty gnarly dirt road. It finishes at U.S. 19, just at the falls. There's a pretty good place to pull off on U.S. 19. Take a rope to get down into the creek, or maybe not if you are hard core and a thrill seeker. I recommend one.
This seems to be a wet weather fall. I've only been there once and it was pretty dry, as you can see below. I've seen photos with full flow and it looks impressive, so I recommend a wet weather visit. Just be careful getting in the creek here. It would be easy to fall and get hurt.
