Cold Harbor Trail is a 4.3 mile moderately trafficked out and back trail located near Northborough, Massachusetts that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible year-round. Dogs are also able to use this trail.
This is an hike through woods and along streams and marsh. Part of the trail is also a road. Not much to see this time of year but I imagine a fair number of birds during the warmer seasons. There are recent signs of beaver activity in the area.
