Take I-77, exit 20. Turn south on U.S. 19. Wolf Creek Falls (US 19) is located on U.S. 19, 3.5 miles from I-77 Exit 20. Roadside at the intersection of CR 19/6. GPS will probably want you to take 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. A rope will be handy getting into this creek. I recommend a wet weather visit. Just be careful getting in the creek here. It would be easy to get hurt here.
