Safe Harbor Park, through the remains of old Safe Harbor Village. (Mostly old foundation holes, though these were very square, deep, and distinct.) Also an old cemetery. Actually a bit longer distance than this, but I didn't count from my car to the trailhead since I wasn't sure I'd actually find it.
The trail map leaves a little to be desired:
I did find it, although it was difficult to follow at times, and kind of devolved into a bunch of logging roads and fresh logging area near the old farm section. The wiggly part after that no longer seems to exist. I followed markers on trees into the woods a bit, but there was no obvious trail and the markers dead ended in a bunch of thorns and deadfall. Instead followed the logging roads across back to the cemetery, then retraced my steps and took the blue shortcut trail to the rest of the foundations.

Big obvious old foundations lined this section at regular intervals:
