Sweetsir Farm Preserve, Yarmouth
This walk is not well-marked. There is a mostly obvious footpath that runs from the parking lot to the river. Avoid the trails that branch off to the left; they lead onto private property. Here’s a bit more info.
Directions: From the intersection of North Road and Ledge Road go north a tenth of a mile to Concord Circle and turn left; go through the subdivision half way around the circle to Old Field Road. Cross the railroad tracks and proceed to a small parking area at the end of the road. The trail extends straight into the woods, approximately 0.3 mile to the river.
