Accessible Trails in Massachusetts State Parks and Forests This is a great website with short descriptions of the trails and links to the State Parks and Forests they are in.
Massachusetts has “two categories of trails, Accessible and Assessed. Accessible Trails are either paved or made from stonedust and are generally one-quarter to three-quarter miles in length. Assessed Trails are actual dirt hiking trails and offer a more rugged experience. Maps have been designed to provide information on grades, cross slopes, trail surfaces and obstacles. Assessed trails are one-half to 2 miles in length.”
