This trail may have existed in the past, but it is all brush now.

This section of trail is marked as "private" on Alltrails maps. The connection to the conservation area exists, although it is missing on the Alltrails map.

This is approximately the actual path.

This segment does not exist.

Parking for 2-3 cars on shoulder.

Parking for one vehicle, per town. But you are half on the narrow road.

According to the Acton Conservation folks, the trails from Nagog Hill Road along the pond shore and up Nagog Hill are on water company property, and should not be used. As of August 21 2020, there was no signage on the trail junction with Conservation Land yellow trail, that indicated the status. The trail looks well-used, despite the restriction, likely because nobody knows about it..

Blazed yellow.

short east-west connector is blazed red.

There's another trail here, blue blazes, from the red trail NE to Tuttle Lane. See town map at
