Appalachian National Scenic Trail
The Appalachian National Scenic Trail is a 2,174-mile footpath along the ridgecrests and across the major valleys of the Appalachian Mountains from Katahdin in Maine to Springer Mountain in northern Georgia. The trail traverses Maine, New Hampshire, Vermont, Massachusetts, Connecticut, New York, New Jersey, Pennsylvania, Maryland, West Virginia, Virginia, Tennessee, North Carolina and Georgia.
The Appalachian Trail (A.T.) is used by day, weekend and other short-term hikers, section-hikers and thru-hikers. Thru-hikers hike the entire length of the Trail in one season. The A.T. began as a vision of forester Benton MacKaye and was developed by volunteers and opened as a continuous trail in 1937.
It was designated as the first National Scenic Trail by the National Trails System Act of 1968. The Trail is currently protected along more than 99 percent of its course by federal or state ownership of the land or by rights-of-way. Annually, more than 4,000 volunteers contribute more than 185,000 hours of effort on the Appalachian Trail.
Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
