The Monadnock-Sunapee Greenway (MSG) is a 50-mile (80 km) hiking trail that traverses the highlands of southern New Hampshire from Mount Monadnock in Jaffrey to Mount Sunapee in Newbury. Located approximately 27 miles (43 km) from the city of Concord, New Hampshire, the trail traverses a rural, heavily glaciated and metamorphic upland studded with lakes, heath barrens, the rocky summits of several monadnocks, and dense woodland of the northern hardwood forest type. The trail is maintained primarily through the efforts of the Monadnock-Sunapee Greenway Trail Club.[1][2]
Notable features along the route include the summit of Mount Monadnock; Eliza Adams Gorge; the classic New England town commons of Nelson and Washington; the New Hampshire Audubon Society's Nye Meadow Refuge; Otter Brook and Andorra Forest; the high heath barrens of Pitcher Mountain, Hubbard Hill, and Jackson Hill; Lovewell Mountain; 8 miles (13 km) of the Sunapee Ridge; and Lake Solitude, a mountaintop tarn near the summit of Mount Sunapee. A number of lakes, reservoirs, ponds, and other wetlands are also located along the route.[2]
