There is a herd path from the Henderson / Preston Ponds / Duck Hole side of McNaughton. It leaves from the trail at what he guidebook describes as the "reamins of Piche's lumber camp," 4.7 miles from Upper Works Parking. The site features a clearing where there is a large iron pulley on the ground, and the tril reaches a substantial brook which flows from McNaughton.
The herd path remains S of the brook, going first through level woods, and then climbing a ridge, with the brook in a deep ravine alongside. A long area of blowdown is encountered. The path basically bores straight through the blowdown, and it works pretty well. You'll waste a lot of time if you try to go around.
Eventually, the brook becomes quite small, and the path is in and out of the brook. There is an obvious point where the brook abruptly ends (disappears into the ground). Here, the path breaks left and then uphill. There was occasional orange flagging on this section a couple years ago. The path will bring you onto the ridge of McNaughton. Turn West for views and the highest point.
