Me, my son, and friend Charles bacpacked along the Panther Creek Falls trail last Fall. We approached from above the falls on the East Cowpen. If you're interested in this trip check out this quick video I made.
A loop of Betty Gap -> C.R.T -> Panther Creek -> East Cowpen -> FS road back is one of my all-time favorites (even the FS road stretch has that Mountaintown view). Well done. I'll be up here this coming week.
