We were just there (WP Franklin) at the beginning of December.
The short answer to your question is yes. If you take a right turn as you exit the campground access road on to RT 78, then travel a few hundred yards, there is a trail on the left just opposite the entrance to Riverwind Cove community on the right. I've forgotten the name of the trail, but there is a small parking area there in front of the trail head. If you look on Google Maps and turn on the satellite view, you can trace your way through there. There look to be a couple of routes through the trail system. I flew a drone over part of it while we were there and it looked decent enough.
This is the link to the location on Google maps so you can see what the parking area looks like. The area is definitely within walking distance to the campground, though.
If you're looking for information about the campground, my wife and I did a relatively short video about our trip there which you can see here:
