The Metacomet Trail is a 62.7-mile (100.9 km) Blue-Blazed hiking trail that traverses the Metacomet Ridge of central Connecticut and is a part of the newly designated New England National Scenic Trail. Despite being easily accessible and close to large population centers, the trail is considered remarkably rugged and scenic. The route includes many areas of unique ecologic, historic, and geologic interest. Notable features include waterfalls, dramatic cliff faces, woodlands, swamps, lakes, river flood plain, farmland, significant historic sites, and the summits of Talcott Mountain and the Hanging Hills. The Metacomet Trail is maintained largely through the efforts of the Connecticut Forest and Park Association.
