Nashua River Rail Trail
The Nashua River Rail Trail is perfect for family-friendly outdoor activities including bicycling, skating, running, and scenic casual walks. Like other trail trails, it has a level 2% grade, rising at the Pepperell (north) end. The section of the rail trail in Groton passes ponds, wetlands, drumlins, and various types of forested areas. The trail is a wide paved surface, with plenty of room for traffic on both directions. There is a grass shoulder for equestrians. Along the rail trail you can access trailheads for JH Rich Forest, Shepley Hill, Longley, Keyes Woods and other GTN trail systems.
