Easiest to get to from the sycamore loop trail head. But if some people are up for a longer hike, then yes, they can connect from the grubb ridge trail head (Patton cave), then hike east to axom loop, to the sycamore loop, which goes to terrill cemetery. No doubt though, that hike will definitely stretch the legs out.
If a group wants to do something like that, I'd be happy to meet them at a trail head. I've been hiking deam much of the summer.
