Canalside Trail begins at McClelland Farm Road and heads north on the former NYNH&H Railroad, crossing the Connecticut River near its confluence with Deerfield River. Approximately a half mile north of the bridge, the trail leaves the old railroad right-of-way and travels on side streets to cut over to the Connecticut River Power Canal. The northernmost mile of the trail travels on the abandoned rail bed along the Connecticut River Power Canal. It passes the fish ladder and Great Falls Discovery Center and ends at Unity Park in the Village of Turners Falls in Montague.
Parking is available at the north end of the trail adjacent to the Montague Town Hall (1 Avenue A).
