This road is currently closed to vehicles between the Water company and Oak Hill St.

Trails are wrong here. There is a trail from Heald Street on west side of brook to this point, then it crosses an old dam to the east side. See town map at:
https://town.pepperell.ma.us/DocumentCenter/View/1055/Pepperell_TrailMap_85x11P_Map1?bidId=
West side of brook is not passable past this point.

Conscience Hill is owned by MIT and hiking is allowed. But intervening parcel between MIT land and Timberlake Conservation property is private.
Private land extends SSE roughly parallel to Timberlake parcel from town line, through this point, to Keyes road.

All main trails have yellow blazes

Trail has been rerouted from here SE toward brook, parallel to brook, then back west to rejoin existing trail. Old trail is impassable after about 40 yards. Not yet on official town map for this property. I have my gps track for this, available if anyone wants to update the map properly.

Called Swamp Trail , from Main path to Scott Road.

The town claims parking here, but it's one vehicle and you need to park on the trail. There is a spur that connects to the trails at the corner of the Ronchetti Area.

Trail crossing is a bit sketchy during wet seasons. Cross narrower portion 5 yards upstream.

Signage states private property, but walking the trail is allowed as long as you stay on the trail and have pets leashed. Warns of video surveillance.

Land north of boundary is not owned by Concord Conservation. Hiking is allowed per posted rules.
