Rode this trail yesterday with the wife and kids. The trail in in great condition and very well marked. My only complaint related to riding it with kids was there are several blind street crossings right in a row (bridges coming over the canal) where there is quite a bit of traffic. Its hard for motorists to see bike, and bikes to see motorists at these intersections.

The short road section is not too bad, though one of the streets looked a little sketchy alongside some old industrial building that is falling down.

This trail was really enjoyable. It has nice views of the canal, surrounding hills, forest, and a cute bridge over the Conn. River. At the start of the trail there is a nice park with a playground and at the end is a railroad transfer that my kids I know will enjoy!

Took the grandkids up to ride this short but nice trail in August. We started at McClelland Farm road just across the street from Guilford RR yard.(old B&M)
It starts on a build trail to pick up the Old NYNH&H R.R. branch and then crosses the Conn. river on what is reported to be the oldest RR bridge over the river. In a short distance is used a short section of small streets to get over to the start of the canal section. The ride along the feeder canal for the power plant has lots of wildlife to see. We saw ducks and geese and the other side where the road and the salmon fish research lab is and can be fished. After we passed where the R.R. spur line crossed over to the mills on the west side you get closer to the other side and can see the southworth mill and some others. At the underpass by the fish ladder(you can visit this in the spring when the salmon and others are heading upstream to spawn) you can make a right to visit the Great Falls Discovery Center which is housed within a complex of old mill buildings and includes open habitat exhibits and fish tanks. Admission is free. At the northern end is the Turners Falls dam and Barton's Cove and small park.
