Monadnock Recreational Rail Trail

Salem/Londonderry Rail Trail
Salem - Manchester
This Trail is a paved trail suitable all bikes. While many other maps cite the trail as starting at the state line, it is just a grassy shoulder on the side of Rt NH-28, so starting it at Main St by Tuscan Village makes more sense.
