Easy to locate by following directions on the trail page.
Park on Rt 23, Mason Rd.- dirt lot on the left. It is a half mi to trailhead on Morse Rd. The orange barrier is about 100 yards in from the road on the left, so if the leaves have not yet fallen, it may be difficult to see, but it should be rather obvious that the trail is there. A very short section also goes further south towards Townsend.
10.4 miles to the Mason Village depot. Average grade 2.8% going northbound. Therefore, you are going up hill, but you hardly notice. The road surface of crushed gravel, as a base, is very flat. With each crossing of a motor vehicle roadway, there are barriers and signs to warn you.
The trail is in excellent shape with some water across the trail, probably collecting in depressions caused by ATVs. This occurs beyond Pratt Pond at the top of the hook, but not so difficult that one cannot get around them. It was probably more obvious due to severe rain over the past 48 hrs.
Nice vistas and scenery along the way. At approximately 4 miles from the trailhead, there is a granite quarry loop on the left. I did not take it, so can offer no report.
At the end of the trail (9 miles), you will encounter a barricade that marks the intersection with Rt. 31. You should walk down to the highway and then you can ride on Rt 31 (take a left) to reach Old Wilton Road on your right. There is a bridge to cross. It is one more mile to the old depot in the center of town. Be careful on Rt. 31. Large trucks go very fast.
This trail is historically significant in that Henry David Thoreau, on September 6, 1852, rode this line (Peterboro’ & Shirley Railroad) from Ayer (Groton Junction at the time) [after riding the Fitchburg line from Concord to Ayer]. Reaching Mason Village (Greenville), he walked to Peterborough, stayed the night and continued on to the summit of Grand Monadnock, on foot. Later in the day, he descended to Troy, NH, and returned the same day to Concord, via the Cheshire RR, and, at Fitchburg, the Fitchburg RR.
