New Haven and Northampton Canal Greenway

The New Haven and Northampton Canal Greenway (NHNCG) is a proposed and partially completed, paved rail trail and non-motorized commuter route along the former right of way of the New Haven and Northampton Railroad. It currently has 63 miles (101 km) open, and when complete it will be 81.2 miles (130.7 km), running between Northampton, Massachusetts and New Haven, Connecticut. The NHNCG name is an effort to unify and promote a regional trail name for the individual trails that it comprises. The New Haven & Northampton Canal Greenway Alliance (NHNCGA) represents seven nonprofit trail groups that advocate for the individual trails. As of 2025, 15 of the 16 municipalities through which the trail runs have officially supported the unified NHNCG name. The NHNCG is a part of the greater New England Rail-Trail Network.
