GB, the path leads straight to the Newman headstone. There are many separate paths within that cemetery. Take it from someone who's been going there for 15+ years, and Ghost who's been going for 40+ years... Even in the thickest overgrowth of summer, there are paths that are clearly marked.
Nobody tends the Grove enough to try and regrow the foliage. Attached are pictures from 2008, 2009, and 2010 that show the same path to the same stone. The 2010 picture is actually taken from behind the Newman stone, facing the cemetery entrance.
