Trail maps are available at trailhead. Singletracks are found throughout off main fire road. Some sweet fast singletrack available. Hilly trail along power lines. Nothing too technical, just some fast singletrack and climbs.
From I-95 N take exit 16B toward Westwood. Merge onto MA-109 W/High St. Follow for about 4.4 miles, turn left onto North St. Adams Farm will be on your right a little over a mile down North St. Adams Farm is fronted by a white fence, turn onto the dirt road and park by the red barn.
