Mt Lincoln is a 3.5 mile lightly trafficked loop trail located near Amherst, MA. The trail is rated as moderate and primarily used for hiking, walking, and trail running.
The 1,234 ft Summit to Mt. Lincoln includes a tower with panoramic views. The summit can be accessed by a network of trails, some of which are visible on alltrails.com maps. The Metacomet Monadnock trail (white blazes) comes through the summit but is presently being rerouted due to private landowner, so the the M-M blazes can be confusing. (At this time, you can use the indicated trailhead on Amherst Rd., but following the white blazes on the return trip does not lead to the same starting point, requiring some backtracking on the road, so keep your eye on the alltrails app with GPS.)
