Rarely seem a human out on these trails, which makes it super nice. Beautiful wildflowers, white tailed deer, and porcupines! Some trap rock along the way. Follow the Metacomet/Monadnock (NET)/Robert Frost to Norwottuck summit, or even better, to the Notch visitors center and back will give you about 9-11 miles. If you decide to make a loop on some of the side trails, they are either wetlands or sporadically marked...or both. Some day I will add this route into my Seven Sisters hike.
