The 5.5 mile Goffstown Rail Trail follows the former Boston & Maine railroad right of way from the Piscataquog River near the Main Street bridge in Goffstown, New Hampshire to the Manchester city line near in Pinardville. Running parallel to Mast Road and the Piscataquog River, eventually the Goffstown trail will connect to Manchester’s Piscataquog Trail. Most of the trail is useable on foot or bicycle. The surface is rough or eroded in some places, so road bikes are not recommended.
