The Northern Rail Trail follows a section of Boston & Maine’s abandoned railway heading southeast from Lebanon, New Hampshire that once went to Boston, stretching across the Mascoma Valley in central New Hampshire. The 23.8-miles between Lebanon and Grafton follow the Mascoma River and passes beside Mascoma Lake. The Merrimack County Section is now connected to this section, making the 46 mile trail the longest in New Hampshire. The unpaved trail has a mix of surfaces, including stone dust, wet areas and some coarse gravel. Cycling is now possible on most sections. Local snowmobile clubs have constructed bridges and use the trail heavily during the winter. Access the Lebanon trailhead near the Lebanon College campus at the intersection of Taylor and Spencer streets in Lebanon. The Grafton trailhead is across from the general store on State Route 4 east into town. There is additional parking off of Rt. 4 in Enfield and Canaan.
